Electromagnetic Compatibility.
800 Series Metering Flow Switches have been Safety Certified by RWTUV as a low voltage, Class III
device.
Section 6 Installation
CAUTION!
It is generally undesirable to mount any plumbing connections directly over
electronic controls or instruments.
WARNING!
If the 800 Series flow sensor is mounted in a vertical pipeline, any leakage from the topmost
connection could enter the unit and cause permanent damage to the electronics.
For applications where there is condensation, moisture, dampness, or dripping water,
please contact Proteus Technical Support for other product recommendations.
Pipe or tubing mounting
If rigid piping or tubing is used, the 800 Series metering flow switch may be supported by direct
connection to the pipe or tubing.
Panel mounting
To mount the sensor behind a panel, two of the faceplate securing screws will need to be replaced with
longer screws to compensate for the thickness of the panel. Ensure that the screws are not so long that
they will touch the bottom of the tapped hole, or rip through the back of a plastic body if over-tightened.
Evenly space up to six holes for 8-32
screws on a 2.5” circle. Using the two holes
on the horizontal plane is usually sufficient
to support smaller flow sensors and all
plastic sensors. If you wish the rotor to be
visible, cut a 1¾” diameter hole with the
same center.
1. Remove screws holding the faceplate to
the sensor body.
2. Place the sensor behind the panel and
insert the longer screws you have
selected.
3. Secure the screws in the body with a
torque of ~ 10 in-lb. (Finger tight with a
flat-blade screwdriver.).
