4. Flow Measurement
Introduction
Flow measurement is the quantification of bulk
fluid movement. Flow may be measured by
measuring the velocity of fluid over known area.
A flowmeter is an instrument used to measure
linear, nonlinear, mass or volumetric flow rate of a
liquid or a gas.

11. Introduction
Turbine flow meter (better described as an axial turbine)
translates the mechanical action of the turbine rotating
in the liquid or Gas flow around an axis into a
user-readable rate of flow (m3/h, gpm, lpm, etc.). The
turbine tends to have all the flow traveling around it.
Turbine flowmeters now constitute 7% of the world
market.
Turbine flow meters are used for the measurement of Air,
natural gas and liquid flow.
Turbine Flowmeter

12. Working principle…………………
Turbine flowmeters use the mechanical energy of the
fluid to rotate a “pinwheel” (rotor) in the flow stream.
Blades on the rotor are angled to transform energy from
the flow stream into rotational energy. The rotor shaft
spins on bearings. When the fluid moves faster, the rotor
spins proportionally faster.
Shaft rotation can be sensed mechanically or by
detecting the movement of the blades. Blade
movement is often detected magnetically, with each
blade or embedded piece of metal generating a pulse.
Turbine Flowmeter

13. Working principle
Turbine flowmeter sensors are typically located external to
the flowing stream to avoid material of construction
constraints that would result if wetted sensors were used.
When the fluid moves faster, more pulses are generated.
The transmitter processes the pulse signal to determine
the flow of the fluid. Transmitters and sensing systems are
available to sense flow in both the forward and reverse
flow directions.

14. Metal tube Rotameter
● Metal tube flowmeter adopts variable area measuring
theory, which is applicable for measuring liquid and
gases and steam, it is all-metal construction. it has
local indication, remotely transfer, anti-corrosion
type, high-pressure type, explosion-proof, etc.
● It has 0-20mA, 4-20mA standard analog signal
output and local indication, accumulation, digital
communication, field modification and measure
parameters, different power supply function.
● It is widely applicable in petrol, chemical, power
supply, pharmacy, food, water treatment industry
etc.

15. Vortex Flow Meter
● A vortex flow meter is a versatile flow measuring device
which covers a wide range of fluids like steam, liquid and
gas.
● Works on the principle of Kármán Effect, which states that
when flow passes by a bluff body,a repeating pattern of
Swirling vortices is generated.
● One reason they are widely used for steam flow
measurement is that they can tolerate the high
temperatures of steam, as steam is the most difficult to
measure.

20. Thermal Mass Flow Meter
● A thermal mass flow meter is a precision instrument that
measures gas mass flow and is used in various
industries with a wide range of applications.
● Thermal mass flow meters, also known as thermal dispersion
or immersible mass flow meters comprise a family of
instruments for the measurement of the total mass flow rate of
a fluid, primarily gases, flowing through closed conduits.
● Thermal gas mass flow meter is designed on the basis of
thermal dispersion, and adopts method of constant differential
temperature to measure gas flow.

21. Working principle
Thermal flow meters use the thermal properties of the
gases to measure the flow of a gas flowing in a pipe or
duct.
The flowmeter contains two platinum resistance
temperature sensors. The thermal flow meter operates
by monitoring the cooling effect of a gas stream as it
passes over a heated sensor.
Gas flowing through the sensing section passes over two
sensors one of which is used conventionally as a
temperature sensor, while other is used as a heater.
Thermal Mass Flowmeter

22. Working principle….
The temperature sensor monitors the actual process
values while the heater is maintained at a constant
differential temperature.
The greater the gas velocity, the greater the cooling
effect and power required to maintain the differential
temperature.

23. Working principle….
The measurement of heater power is therefore a
measurement of the gas mass flow rate.
m = Kq/(Cp(T2 – T1))
The mass flow (m) is calculated on the basis of the
measured temperature difference (T2 - T1), the meter
coefficient (K), the electric heat rate (q), and the
specific heat of the fluid (Cp),

26. Coriolis Mass Flow Meter
● Coriolis mass flow meter are the leading precision flow and
density measurement solution offering the most accurate
and repeatable mass flow measurement for liquids, slurry
and Gases. The coriolis flowmeters offer the most accurate
measurement available for virtually any process fluid, while
exhibiting exceptionally low pressure drop.
● Coriolis mass flowmeters measure the mass flow of liquids,
such as water, acids, caustic, chemicals, Oil and
Gases/Vapors.

27. Internal Structure and Major parts:
A) U - Tubed B) Straight Tubed C) Triangular Tubed

28. Working principle:
A Coriolis meter is based on the principles of motion
mechanics. When the process fluid enters the sensor, it is
split. During operation, a drive coil stimulates the tubes to
oscillate in opposition at the natural resonant frequency. As
the tubes oscillate, the voltage generated from each
pickoff creates a sine wave. This indicates the motion of
one tube relative to the other. The time delay between the
two sine waves is called Delta-T, which results to generate
differential voltage Delta-V which is directly proportional to
the mass flow rate.
