Why Calibrate Ultrasonic & PD Flowmeters

Both ultrasonic and positive displacement flowmeters experience drift over time — each for different reasons:

Ultrasonic Flowmeter Drift Factors:

Sensor coupling degradation

Pipe wall buildup affecting signal path

Temperature changes influencing sound velocity

Aging electronics affecting timing accuracy

Flow profile or process condition changes

PD Flowmeter Drift Factors:

Mechanical wear on internal components

Increased friction or drag

Contamination or deposits affecting displacement accuracy

Changes in viscosity impacting meter behavior
