Presentation Overview
Flow meter technologyPositive Displacement - Principle of
operation.Ideal applicationsWhat's newIntroducing the new
generation MX series Flowmeters.
Flow Meter TechnologiesThere are 4 general groupings by which a
flow meter can be categorised, according to the technology adopted.
Velocity Inferential Mass Volumetric
Volumetric Flow MeterDirectly measure the total volume of the
fluid passing through the pipeOval GearRotaryNutating
DiscBi-RotorSpur GearOscillating Piston
Typical ApplicationsVolumetricBatchingDispensingDosingFuel
ConsumptionApplications requiring accurate totals
Positive DisplacementFlow Meter
Principle of OperationA precision engineered measuring chamber
houses a pair of oval rotors which rotate during flow
conditions
Principle of Operation
As the Rotors turn they sweep a measured volume of liquid
through the measuring chamber
Measured Volume
Principle of OperationEach 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 OperationOur Sensor Boards (PCB) incorporate two
types of switches. Reed Switch Mechanical Switch
Hall Effect SwitchSolid State
Calculating Flow RateThe 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
checksExample .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 mlAn Electronic device (Signal Conditioner) is used
to convert these pulse outputs to Flow Rate and Total Flow
