Installation
The jet spray cleaner eliminates routine, manual sensor
maintenance by cleaning the sensor with water or
compressed air. Flow through the cleaner can be
controlled by a solenoid valve.
Note: The jet spray cleaner can be used with
handrail mounting assembly (PN 11275-01, not
shown) or can be mounted through conduit as shown
below.

*The minimum inlet pressure is required to open a check valve, which
prevents the flow cell from draining if sample flow is lost. Removing
the check valve lowers the inlet pressure requirement to a few feet of
water head.
