Digital Manometer Differential Pressure Gauge

Digital Manometer Differential gauges are professional instrument for measuring gauge & differential pressure in the ranges of ±13.79 kPa / ±2 psi / ±55.4 H2O. Gauge pressure is the pressure values zero-referenced against ambient air pressure while differential pressure is the difference in pressure between two points. It has dual input ports for measuring differential pressure. A differential pressure gauge is a pressure measuring instrument that measures the difference in pressure at two different points. In addition to measuring differential pressure, it is often used in conjunction with throttling devices (such as orifice plates, Venturi tubes, etc.) to measure fluid flow, and can also be used to measure liquid levels (such as differential pressure level gauges) and pipelines, tower equipment, etc. resistance (i.e. pressure drop between two points), etc.
