DPM Precision Multigas Flow Meter

May 3, 2018

An intelligent digital DPM precision multiparameter gas flow meter is designed to measure mass flow rates, pressure, and the temperature of clean, non-corrosive process gases. The unit's user-defined mixture functionality allows the creation and the storing of up to 20 custom gas mixes with up to 5 different gases each.


The DPM allows on-site selection of 30 different local gases via the optional OLED/joystick interface or remotely via the RS-232/RS-485 or optional Modbus RTU interface.
