4.4 1.25” BSP Thread installation
The sensor is supplied with both an O-ring and a Gasket. To use the supplied O-ring, the mounting hole
requires a chamfer to be machined around the upper edge. If a chamfer cannot be created, then the supplied
Gasket should be used. Ensure that sufficient space is allowed around the sensor flange for the cable to bend.
4.4.1 Using the O-ring
The recommended mounting hole and chamfer size for the O-ring is shown below.
Fit the O-ring above the male thread on the sensor. Ensure the O-ring is centred and sits within the chamfer;
tighten the sensor using a adjustable spanner until the sensor face is flush with the top of the tank and a
torque of 50 Nm is achieved.
