The TruFlo Delta-P series differential pressure gauge is an all-plastic corrosion resistant differential pressure gauge and relay switch. The LCD digital display is selectable between psi and bar. The Delta-P pressure gauge comes with an SST mounting kit. The rugged design has a NEMA 4X enclosure.

The Delta-P measures the differential pressure between the upstream port or (high) and downstream port (low) to provide indication and notification of a filter/strainer element (change, clean, or replace), pump,(choked flow), valve (cavitation) or tank (level). The pressure difference in turn acts on a piston/magnet assembly within the Truflo device activating the programmable latching relay switch which can be used for alarm notification, pump or valve shut-off.
