Install Pressure Sensor
The pressure sensor is mounted on one of the tank sides approximately 2 inches
from the bottom. If the tank has a vertical height greater than 10 feet contact FRC, a
different sensor may be required.
Pressure sensors are interchangeable. It is recommended that the calibration
procedure be performed if the pressure sensor is changed.
Note: When mounting the pressure sensor on a tank with thin walls, less
than 3/8", it is recommended that the tank wall be reinforced at the sensor
mounting location.
Pressure Sensor Installation
Note: Do not mount the sensor in the bottom of the tank. Sediment may collect in the port
and cause sensor failure.
1. Measure and mark mounting location for sensor. (Mounting hole should be
approximately 2" from bottom of tank.) Make sure there is clearance for sensor
and cable before drilling hole. Refer to Figure 3 for dimensions.
2. Drill and tap a 1/4 NPT hole.
3. Apply sealant around base and threads of pressure sensor.
4. Screw sensor into hole.
5. Connect sensor cable. (Refer to Wiring Section.)
Thin Wall Adapter Installation
The thin wall adapter kit includes the adapter, two 10-24 x 5/8" screws, 5 minute
epoxy, and a mixing stick.
1. Measure and mark mounting location for adapter. Make sure there is clearance for
adapter, sensor, and cable before drilling hole. Refer to Figure 3 for dimensions.
2. Drill and tap a 1/2 NPS hole.
3. Screw the adapter into the hole.
4. Use the adapter as a template and drill and tap two 10-24 holes for two screws.
5. Back adapter out of hole and apply 5 minute epoxy to back of flange, on threads,
and in two 10-32 through holes.
6. Screw adapter into hole and secure with two screws.
7. Allow the epoxy time to set.
8. Apply sealant around base and threads of pressure sensor and screw into adapter.
9. Connect sensor cable. (Refer to Wiring Section.)
