|How does Sponsler calibrate the Precision Turbine Flowmeter?
Sponsler precision turbine flowmeters are placed in a flow line and
subjected to a gravimetric calibration or ballistic prover process, depending on the size
of the meter. A 10-point calibration is performed over its range at 10 different points to
ensure and document linearity and repeatability. The 10-point calibration is standard for
most Sponsler meters. A calibration sheet is furnished with each meter, showing actual
performance of the meter under calibration lab conditions. Additional calibration points
can be performed upon request at stated rates.
