Revision 3 Ultrasonic Fluid Sensor.
The Revision 3 of the ultrasonic fluid sensor uses updated electronics to improve reliability of
the sensor. Unlike the earlier versions, it is not necessary to apply grease to the sensor body.
The fluid sensor is located on the inlet side of the peristaltic pump, mounted to the right front
side of the sampler electronics enclosure. The pump tubing passes through the fluid sensor body. See
