Differential Pressure Gauge
Differential Pressure Gauge has two bourdon tubes, it measures two different pressures and it indicates the differential pressure. They are used in heating systems (supply and return lines) and filter systems.

Pressure gauges mounted directly on piping should be assembled with reasonable care, always using the wrench grip provided on the pressure connection to secure it to the threaded fitting.
Do not use the gauge case as a means of tightening the connection.
In order to extend the service life and continued accuracy, the gauge should be protected as far as possible from effects of mechanical vibration. It is desirable to isolate it from severely vibrating machinery.
The gauge may be rigidly mounted to a non-vibrating surface and connected to the pressure source using flexible tubing.
Tip: we recommend the use of Needle Valves
