Back-Mounted Tri-Clamp Diaphragm Pressure Gauge

Rear connection and dial orientation

The process connection sits behind the dial rather than below its edge. This arrangement makes the relationship between the measuring port and the viewing direction an important part of the layout. The gauge provides a local visual indication of liquid pressure at a tank or pipe connection.

Choosing the clamp connection

The listed 1–2 inch sizes describe the connection selection. Compare the mating ferrule profile, flange outside diameter and gasket seating dimensions when choosing the assembly. Nominal size alone does not describe every mating dimension. Allow room behind the dial for the clamp and for access to its fastener.

Materials and measuring specification

SS304 and SS316L are listed material options for this gauge. Specify the required materials for the process-contact components as part of the instrument selection. The dial unit, measuring span and required calibration should be selected together for the intended pressure observation point.

Reading access and routine care

Position the dial where its pointer and scale remain visible during normal inspection. Consider nearby pipework and insulation when reserving space for removal. Routine instrument care includes checking the visible connection and dial condition, keeping the face readable and arranging calibration under the site instrument maintenance procedure.
