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

Volumetric Flowmeter
‘Directly measure the total volume of the fluid passing
through the pipe’

Flow Measurement Technology

Positive Displacement
Flowmeter

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

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

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

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

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
