Filtertechnik are proud to be an official distributor of US-made Differential Pressure Plus products. Differential Pressure Plus Inc. has been designing and manufacturing differential pressure switches, gauges and status indicators in Branford, CT, since 1991. The vast majority of applications involve water and fuel filtration, however, differential pressure gauges can also be used in applications such as:

Liquid levels in tanks.
Monitoring of flow rates.
Balancing valves.
Monitoring pump life and performance.
Monitoring scale/sediment buildup in heat exchangers and other critical equipment.
Leak detection.
Differential pressure is one of the most adaptable, yet underused tools in the industry and we want to change that.

The product range can be split into two groups, low cost differential indicators and precision differential gauges. The precision range of units can be supplied as a switch only, a gauge only or a gauge and switch combined.

Differential pressure measurement can be achieved by two different methods, diaphragm and piston. Below is a quick guide to the pros and cons of each method.
