Installation Instructions
Sensor
Using dimensions from calibration software, cut PVC pipe to specified length, this will serve
as the wave guide
Glue the sonic reflector retainer to the end of the tube, using PVC cement
Insert sonic reflector in wave guide
Insert wave guide into the sensor housing and tighten the allen screws fastening the wave
guide to the sensor housing
Caution do not over-tighten these screws, this could distort the wave guide and prevent the
free travel of the sonic reflector within the guide
The sensor is now ready for installation in the appropriate tank
Water Tanks
Select a location which will allow the wave guide to terminate at the deepest point of the tank.
*Avoid termination in sump*
Avoid locations where the tank fill stream would hit the wave guide
At the selected location cut a 2.312” hole to accommodate a 2” NPT thread, if you are
using a flange to mount sensor you will require a 2.375 opening
Caution use a sensor with the W tank designation
Install sensor in tank
On threaded installations use Teflon thread tape on the male thread
On flange installations use supplied gasket
The control cable should be orientated towards the display module
Caution on threaded installations be sure the wrench used to tighten the connection is used
only on the octagon flange at the bottom of the housing
