Why calibrate a liquid flow meter?

Key elements in determining compliance with national and international standards are the validity and accuracy of inspection, measurement and test results. A liquid flow meter performance degrades over time, liquid flow calibration must be performed to provide the necessary level of confidence in the results of the tests being conducted.

There are several reasons why a liquid flow meter falls out of calibration: physical modifications may occur from corrosion or dirt within the process; internal parts degrade slowly and will eventually have an impact on meter performance or flow meter may receive mechanical or pneumatic impacts resulting from process variations, improper installation or initialization or procedure.


Coating and wear of the flow tube


Bearings affected by chemicals or dirt; bearing service affects calibration; rotors wear

Variable Area

Material build-up; clogging; tube abrasion


Liner damage; electrode coating

Positive Displacement

Dirty liquids, corrosion and abrasion change the volume; bearing wear degrades accuracy; gear service affects calibration; solids can cause plugging

Differential Pressure

Orifice plates, nozzles and venturis are subject to wear: orifices plate get knocked out of position. Pitot tubes become clogged


Changes in the sonic properties of the fluids; lack of contact between transducer and pipe wall


Flow meter mounted improperly in pipe; vibration; shedder wear
