Figure 1.
The pump tubing is held in place in the sensor block by a hinged cover and two screws. To
remove the pump tubing from the sensor, first remove the two screws from the cover and then open the
cover up.
To install the pump tubing in the fluid sensor, first route the pump tubing through the fluid
sensor and then the pump body, so that 3” of tubing extends from the inlet (left) side of the fluid sensor.
(Note: Order part number MS889923 for a 22” piece of pump tubing, or MS566925B for bulk tubing if
replacing the pump tubing). Do not stretch tubing in fluid sensor. Then, run a test cycle with the intake
hose disconnected to make sure the pump tubing is properly seated in the pump body. Rotate the pump
tubing as required to seat it. (Note: the pump lid must be on in order for the pump to run) With the
pump tubing properly seated, close the hinged cover on the fluid sensor and secure it with the two
screws. Remove the quick disconnect fittings from the old pump tubing and inset them into the ends of
the newly installed tubing. Connect the discharge hose to the pump tubing.
Fluid Sensor Types.
Manning offers two different types of fluid sensors on its peristaltic samplers. The continuity fluid
sensor detects the presence of fluid by passing an electric signal between two probes in the sensor, using
the fluid as a conductive medium. The continuity fluid sensor works in a wide range of applications, as
