transducers are installed firmly, etc.
5.2 Zero Set Calibration

If the zero set point is not at true zero flow, a measurement difference may occur. The smaller the physical
measurement capacity is, the larger the measurement difference from the zero point will exist. Only when zero

ed to a definite degree, as compared with the physical measurement capacity, can the measuring
difference from zero point be ignored.
For an ultrasonic Flowmeter, the measurement difference from zero point cannot be ignored at low flow. It is
necessary to perform a static
zero set calibration to improve low flow measurement accuracy.
Press Window M42 to set the Zero, press

that result from application on different pipes. The scale factor entered must be one that results from actual
calibration.
The scale factor can be input in Window M45.
