A flow meter is a test device used to calculate the flow rate of process fluids and gases in industrial plants and facilities. The flow rate denotes to the speed at which a process fluid is moving through pipelines, orifices, or vessels at a given time.
Control and instrumentation engineers measure this value to screen and regulate the speed and efficacy of industrial flow processes and devices.
Ideally, test devices must be ‘reset’ from time to time to stop having inaccurate readings.
For example, a bathroom scale that indicates 10lbs when nobody is standing on it needs to be recalibrated to specify an initial zero value.
I n industrial settings, Liquid Flow Calibration is performed to ensure that measurements are accurate permitting operations to proceed in a safe and timely manner.
A sampling system is used to obtain a small product sample from a pipeline with the same proportions of oil, water, and contaminants as a running stream. OGSI supply sampling and analyzer skids that operate non-stop since fast loop sampling bypasses the main line. The sampling system is considered to be the most cost-effective solution in cases when analyzers are not required per project specifications. Check here to know more about sampling system.
The document discusses different methods for calibrating pipe provers used in flow metering systems, including the water draw method, gravimetric method, and master meter method. The master meter method directly uses the process liquid and allows calibration under actual field conditions. While not as commonly used as the water draw method, the master meter method has advantages such as avoiding the need to drain and clean the system when changing liquids, and providing a more accurate assessment of the metering system's performance under normal operating conditions. The document argues that the master meter method may be the most suitable calibration approach when the required measurement uncertainty is medium to high.

The document discusses calibration procedures for various non-analytical laboratory equipment. It states that laboratories must have documented calibration procedures for equipment that directly or indirectly affects test results. The procedures should include recording traceability to standards, verification of accuracy, recording calibration status, and preventing unauthorized adjustments. Equipment that requires calibration includes centrifuges, water baths, autoclaves, pipettes, storage chambers, and equipment that measures hemolysis, icterus and turbidity indices. Specific calibration procedures are described for these various pieces of equipment.
Calibration of the measuring instrument is the process in which the readings obtained from the instrument are compared with the sub-standards in the laboratory at several points along the scale of the instrument. As per the results obtained from the readings obtained of the instrument and the sub-standards, the curve is plotted. If the instrument is accurate there will be matching of the scales of the instrument and the sub-standard. If there is deviation of the measured value from the instrument against the standard value, the instrument is calibrated to give the correct values.
All the new instruments have to be calibrated against some standard in the very beginning. For the new instrument the scale is marked as per the sub-standards available in the laboratories, which are meant especially for this purpose. After continuous use of the instrument for long periods of time, sometimes it loses its calibration or the scale gets distorted, in such cases the instrument can be calibrated again if it is in good reusable condition.
Even if the instruments in the factory are working in the good condition, it is always advisable to calibrate them from time-to-time to avoid wrong readings of highly critical parameters. This is very important especially in the companies where very high precision jobs are manufactured with high accuracy.
All the measuring instruments for measurement of length, pressure, temperature etc should be calibrated against some standard scale at the regular intervals as specified by the manufacturer. There are different methods or techniques of calibration, which are applied depending on whether it is routine calibration or if it is for special purpose where highly accurate calibration of the instruments is desired. In many cases different methods of calibration are applied for all the individual instruments. No what type of calibrations is being done, all of them are done in the laboratory.
The calibration of the instrument is done in the laboratory against the sub-standard instruments, which are used very rarely for this sole purpose. These sub-standards are kept in highly controlled air-conditioned atmosphere so that there their scale does not change with the external atmospheric changes.
To maintain the accuracy of the sub-standards, they are checked periodically against some standard which is kept in the metrological laboratories under highly secured, safe, clean and air conditioned atmosphere. Finally, standards can be checked against the absolute measurements of the quantity, which the instruments are designed to measure.
Metering systems are used to accurately measure oil and gas volumes being sold along the supply chain. For small volumes, oil is directly measured in storage tanks, while large volumes use automated LACT units. Natural gas can be measured using orifice meters, which determine flow rates based on differential pressure. Fiscal metering, which is used for custody transfer, employs meters, analyzers, and prover loops to ensure measurements are accurate to within 0.3% for liquids and 1.0% for gases. The data is used to calculate invoices and payments between partners.

This document discusses methods for measuring oil, gas, and water production from wells. It begins with an introduction to the importance of metering for accounting, performance analysis, and reservoir management. It then reviews conventional metering methods including turbine, positive displacement, orifice, coriolis, and ultrasonic meters. Alternative metering without separation is also discussed, including multiphase flowmeters using nuclear models. Permanent downhole flowmeters are introduced as well, with communication systems and data analysis described. Major companies involved in production metering are also mentioned.
Turbine flow meters measure volumetric flow by detecting the rotation of a rotor within a housing as fluid passes through. They provide accurate, repeatable measurements with a fast response time. To ensure high accuracy, turbine meters must be calibrated using a positive displacement calibrator that can achieve errors of 0.05% or less. Viscosity affects turbine performance, so meters should be calibrated at the operating viscosity or equipped with technology to correct for viscosity and density variations caused by temperature changes. With proper calibration and correction methods, turbine meters can accurately measure varying flows.
Fluke Corporation: Gas Custody Transfer CalibrationTranscat
This document discusses calibration considerations for orifice plate based gas flow computers used in custody transfer applications. Differential pressure meters are commonly used despite ultrasonic meters having advantages. Calibration is important due to the financial impact of errors in custody transfer measurements. Test equipment selection depends on the type of inputs to the flow computer. Procedures involve verifying and adjusting pressure, temperature, and current inputs through multiple measurement points. Safety, isolation, and proper setup are important to get accurate results and verify calibrations.
Calibration of air pollution monitoring instruments is important to ensure reliable measurements. Instruments can drift over time so they need to be calibrated regularly according to a schedule. Calibration involves comparing the instrument to absolute standards to check for any variation and ensure precise and accurate readings. Recognizing the need for reliable data, Envirotech has set up various reference and calibration facilities, including for flow, temperature, humidity, vacuum, time, and more. They calibrate their own instruments using these facilities to validate measurements at low cost according to customers' needs.

This presentation covers a SCADA automation project for a water distribution network. It will include operations analysis of the existing network, recommendations for zone isolation valves, flow meters, and leak detection. The network will be divided into 12 zones that can each be isolated by motorized valves from the SCADA system. Approximately 144 existing valves will be retrofitted with actuators. 22 flow meters will be installed on main transmission lines to monitor flows. Leak detection will utilize mass balance, real-time transient modeling, and single pressure point analysis methods within the SCADA system.
1. The performance of boilers decreases over time due to factors like poor combustion, fouling, and improper maintenance. Regular efficiency testing helps identify efficiency losses and issues in need of corrective action.
2. The purpose of a performance test is to determine the actual efficiency and evaporation ratio of a boiler and compare it to design specifications. It tracks variations in efficiency over time and the impact of energy efficiency improvements.
3. Boiler efficiency can be tested via the direct method, which compares energy output in steam to energy input in fuel burned, or the indirect method, which calculates efficiency as 100% minus the sum of measured heat loss factors. Both methods require measuring various operational parameters.
The document discusses some critical issues with air pollution monitoring that can affect the reliability of the data generated. It summarizes that both the monitoring equipment and personnel play a role in data quality. Specifically, it notes that monitoring instruments often are not calibrated frequently enough and personnel are often not adequately trained. It also discusses challenges with calibrating equipment in the field and suggestions for improving the calibration process, including developing portable calibration devices. Overall, it argues that unreliable data can result if conditions of both the monitoring equipment and personnel are not properly addressed.

Ch-4: Measurement systems and basic concepts of measurement methodsSuraj Shukla
This document provides an introduction and overview of measurement systems and concepts. It discusses:
- The basic components of a generalized measurement system, including sensing, conversion, manipulation, processing, transmission and presentation stages.
- Key definitions and concepts in measurement like accuracy, error, calibration, threshold, sensitivity and hysteresis.
- Classification schemes for transducers based on factors like the physical phenomenon, power type, output type and electrical phenomenon.
- Types of transducers like active vs passive, primary vs secondary, analog vs digital, and examples within resistive, capacitive, inductive and other categories.
The document discusses validation of critical utility systems used in pharmaceutical manufacturing facilities. It focuses on validation of HVAC, water, and steam systems. For HVAC validation, it provides details on DQ, IQ, OQ, and PQ protocols including objectives, responsibilities, tests performed. It discusses user requirements, specifications for HVAC control and monitoring. For water system validation, it discusses purification methods, grade of water, and protocols for IQ, OQ and PQ. It also discusses two types of steam systems - house steam and clean steam - and validation considerations for each.
This document discusses different types of flow measurements. It describes four main types: 1) Primary or quantity meters that directly measure flow rate through volumetric or gravimetric methods. 2) Positive displacement meters that count discrete volumes of fluid flow. 3) Secondary or rate meters that infer flow rate from other measured properties like pressure or velocity. Common examples are Venturi meters, orifice plates, and rotameters. 4) Linear resistance element meters that rely on pressure drop across a tube to determine flow rate, suitable for very small, viscous flows. Primary meters are the most accurate while positive displacement meters can handle a variety of fluids. Secondary meters have varying accuracy depending on the design.
Process control involves continuously monitoring key variables in an industrial process, such as temperature, pressure, or chemical content. Sensors measure these process variables and send the data to a controller for comparison to target setpoints. The controller then sends signals to actuators to adjust input variables, like flow rates or temperatures, in order to maintain consistent quality output that meets specifications. Effective process control requires sensors to measure process variables, actuators to change input variables based on controller signals, and controllers to compare measurements to setpoints and calculate necessary adjustments.
Supersonics are pleased to introduce their Automatic Concentration Monitoring System. This system shall replace the manual & often erroneous process of Titration to maintain concentration in liquid baths in Parts Washing Machines.
Going for a laboratory that is 17025 Certified means that the same has a set standard of testing and calibration services irrespective of its physical size. This standard is therefore used to develop their management system for getting quality and even technical support.
This document discusses consistency transmitters and consistency measurement. It describes the Satron VCT consistency transmitter, which uses LED technology to measure consistency 10 times per second across a wide consistency range for various pulp and paper applications. It emphasizes that proper sampling, laboratory analysis, and understanding how the process affects consistency are just as important as the measurement device itself for achieving accurate consistency control.
Control in process industries is important to precisely regulate all aspects of manufacturing processes. This involves controlling variables like temperature, pressure, flow and level. Process control technology helps manufacturers keep operations running safely and efficiently within specified limits to maximize quality and profitability. It works by measuring process variables, evaluating measurements against set points, and controlling variables through manipulated elements like valves. This ensures consistent products despite disturbances.
In the oil and gas industry, the flow of liquids and gases must be measured during every phase of exploration, production and transportation. Upstream operations span offshore and onshore activities, including well testing, enhanced oil recovery, fractionation, completion, and separation to recover and prepare crude oil and natural gas. These applications demand the highest flow meter accuracy and reliability, as well as long-term stability and a low cost-of-ownership.

2. Introduction
• Gas meter calibration system has become an essential nowadays.
Numerous methods are applied for performing gas meters’ calibration.
• Bell Prover: This is actually a calibrated vessel with well-known volume
characteristics. It is often used as a primary standard.
• The Bell Prover provides a certain volume to the gas meter under test
and thus a direct comparison between the meters' reading and the
volume’s value can be performed. This method is mainly used for
calibrating small domestic and diaphragm meters.
• Gravimetric method: A very precise weighing scale is used to define the
amount of gas that actually flows through the meter during the
calibration procedure. This method is measured to be very accurate.

Test Bench: It is a
comprehensive system
which uses master meters
as reference standards. The
same amount of volume
flows through the master
meter and the gas meter
under test, and the two
meter readings are
compared to each other.
This Gas meter Calibration
method is widely used by
many calibration
laboratories all over the
world. Depending on the
6. Before continuing with the analysis of the Test
Bench method of calibration, it is vital to give
some information about the metrological
characteristics of the most common types of gas
meters. The air enters through the filters and flows
through the master meter.
The flow is adjusted via the control valves and the
speed of the fan. The air passes through the
meter under test and returns to the room exiting
from the fan.
A temperature and a pressure sensor are placed
on each meter (master meter and meter under
test). The test bench must have the capability to
7. • Process Flow Calibration involves calibration of
a flow meter which is at present in use. Periodic
recalibration is needed as flow meter readings will
often go ‘out of phase’ over time due to variable
conditions involved in industrial processes.
• The main difference amid the two procedures is
that flow calibration is done before the meter is
sent out for use while recalibration is done after
the flow meter has been in operation for a while.
• Software tools can also be used to verify the
correctness of measurements after a flow meter
has been calibrated.
