3.3 PROCESS CONNECTIONS
Housing Rotation
Process connections on the transmitter flange are 1/4 - 18 NPT, with a centers distance of 54mm (2.13in) between the
connections. The process connections on the transmitter flange are on centers to allow direct mounting to a three-valve or five-
valve manifold.
Flange adapter unions with 1/2 - 14 NPT connections are available as an option. Rotate one or both of the flange adapters to
attain connection centers of 51mm (2.01in), 54mm (2.13in) or 57mm (2.24in).
To install adapters, perform the following procedure:
1. Position the adapters with the O-ring in place.
2. Bolt the adapters to the transmitter flange using the bolts supplied.
3. Tighten the bolts.
For model 264PS and 264VS it is only possible to have one adapter, with low pressure side flange without process connection
and drain/vent valve.
