For threaded process connections, screw sensor into the opening using a wrench on the NPT Fitting (bottom half for

swaged fittings). Do not overtighten the upper nut on swaged fittings. Use thread tape or suitable pipe compound on the

process connection threads. If flanged, bolt the sensor flange to the mating flange with the proper gasket. Complete the

following steps to mount the transmitter using the threaded flange method:

1. Remove the float retaining hardware, then remove the float.

2. Insert the tip of the sensor through the threaded vessel opening, or flange.

3. Before you completely insert the sensor tip to the bottom of the vessel, you must remount the float(s) and

retaining hardware through an access port, or on the bottom side of the mounting flange.

4. The sensor tip can now be lowered to the vessel bottom and the connection can be made from the threaded NPT

fitting to the vessel or mounting flange. In general, there should not be more than 12 inches of the Sensor

Assembly extending above the vessel.

Welded Flange Mounting

The transmitter can also be mounted to a vessel flange with a flange welded to the sensor. Be sure to use the

appropriate gasket between the flange faces.
