How to Detect Leaks using a Differential Pressure Gauge?

Probably one of the least understood applications of differential pressure gauges involves detecting leaks in a system.

By comparing a reference vessel to a potentially leaking vessel, a differential pressure can be measured and leak can be detected.

As a result, a great deal of time is saved and the results are far more accurate than waiting hours for a drop on a standard pressure gauge.

Due to the fact that differential pressure gauges can measure down to 0.1″ H2O accurately, you will be waiting far less!


Furthermore, differential pressure gauges in leak detection applications can be:

  • Simple and inexpensive (starting around $50).
