Truflo Delta-P Series is industry’s first all-plastic corrosion resistant differential pressure gauge and relay switch. The DPG 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.
