The document provides an overview of flow meter technologies, with a focus on positive displacement flow meters. It discusses the principles of operation for positive displacement meters, including how they directly measure volume by passing measured volumes of fluid through a measuring chamber. The document also outlines applications for positive displacement meters like batching and dispensing. It introduces the new MX series of positive displacement flow meters from Macnaught, highlighting features like increased temperature and pressure ratings, a new mounting system, and hazardous area approvals.

3. Flowmeter Technologies
There are 4 general groupings by which a flow meter can
be categorised, according to the technology adopted.
 Velocity
 Inferential
 Mass
 Volumetric

through the pipe’

Flowmeter

7. Principle of Operation
A precision engineered
measuring chamber
houses a pair of oval rotors
which rotate during flow
conditions
Meter Construction

8. Principle of Operation
As the Rotors turn they sweep a measured volume of
liquid through the measuring chamber
Measured Volume
Measuring Chamber

9. Principle of Operation
• Each of the Rotors are
fitted with magnets on the
top face.
• As the Rotor turns the
magnet activates a switch
which is fixed to a Printed
Circuit Board (PCB)
• This in turn generates a
Pulse Output

10. Principle of Operation
Our Sensor Boards (PCB)
incorporate two types of switches.
 Reed Switch
Mechanical Switch
 Hall Effect Switch
Solid State
Electronics – Printed Circuit Board

11. Calculating Flow Rate
• The K- Factor is … ‘The number of Sensor Pulses per Unit of
Measure’ (Litre or US gallon)
• Each meter is assigned an individual K-Factor calculated during
our calibration checks
Example ….
 A meter has an independent K-Factor 36 (= 36 pulses per
litre)
 Each pulse generated by the meter is the equivalent to
1 Ltr ÷ 36 = 27.8 ml
 An Electronic device (Signal Conditioner) is used to convert
these pulse outputs to Flow Rate and Total Flow
K-Factor

12. The Benefits associated
with a PD Meter

13. Technical Specifications
 Accuracy
• +/- 0.5%
(500ml in every 100 litres)
 Repeatability
• 0.03%
(30ml in every 100 litres)

 No pipe conditioning required
 Suitable for variations in medium
(e.g. viscosity, concentrations, etc. )
