7.2.14.1 Sensor constant C
Sensor constant C is the sensor calibration value for mass flow. This constant is defined when the flowmeter is
calibrated at the factory and can be found on the rating plate.
Sensor constant
+0150.00 kg/h
Caution:
Changing the sensor constant C to a value that differs from the value on the rating
plate of the sensor will result in incorrect mass-flow measurements.
Normally, the sensor constant is changed only when the device is calibrated, e.g. for a validation measurement
for a custody transfer operation.
Note:
The sensor constant must always be preceded by a plus or minus sign. The delivery
default setting is a plus sign. If inlet and outlet section are interchanged when the
device is installed (the flow direction is indicated by an arrow on the sensor), the
transmitter will display a “forward flow” negative measurement value. If the (plus or
minus) sign of the sensor constant is then changed without changing the actual value,
a plus sign will again be displayed. No changes need be made in the disposition of the
electrical connections (wires).
7.2.14.2 Sensor material
The Sensor material function allows the flow tube material code to be entered. This material code can be found
on the sensor rating plate. This setting is defined by the vendor when the device is first put into operation at the
factory.
