REPAIR & PARTS
Signal
The flow sensor has only one moving part, the rotor. If this
is turning properly and there is no signal, the Hall-effect sen-
sor is not operating properly. To check the signal, apply 12
Vdc regulated* power to the red (+) and black (-) leads. Set
a multimeter to voltage reading. Put the positive multimeter
lead on the red wire and the negative lead on the white wire.
Slowly turn the rotor. Voltage reading should swing between
+12 Volts and 0 Volts as the rotor turns. If it does not, the Hall
effect sensor is not working properly. Checking for continuity
is not a useful test of these sensors.
*NOTE: An unregulated power supply can exceed max voltage of
micro powered sensor (gray cable) and damage sensor.
All Seametrics flow sensors are repairable, and can be
returned to the factory or distributor for repair after a Return
Material Authorization (RMA) number has been issued. IP110/210 Parts
