Fluid Components International CMB - Manual (Page 95)

Normally, the sensor constant is changed only when the device is calibrated, e.g. for a validation meas-
urement for a custody transfer operation.
Note:
The sensor constant must always be preceded by a plus or minus sign. The delivery de-
fault 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).
13.14.2 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.
