DPM Precision Multigas Flow Meter


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.
