This Series 770 differential pressure gauge is especially suited for economic and rugged measurement and control of the pressure drop across filters, valves and equipment and for flow measurement and control. Differential pressure is measured in a solid high pressure housing by a free floating precision piston. The piston carries a magnet that is magnetically coupled to a magnet on the gauge pointer outside the pressure housing and indicates differential pressure on a calibrated dial scale.
