Aalborg Instruments’ DPM Flow Meter Features Multi-Gas Functionality

Aalborg Instruments’ intelligent digital DPM precision multi-parameter gas flow meter measures mass flow rates, pressure and the temperature of clean, non-corrosive process gases. The unit’s user-defined mixture functionality allows the user to create and store up to 20 custom gas mixes with up to five 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.

DPM design features include:

  • Flow accuracy (inc. linearity) ± (0.5% RD+0.2% FS) at calibration temperature and pressure
  • 200 to 1 turndown ratio
  • Quick (10ms) response time
  • Two programmable mass flow rate totalizers
  • Free, easy-to-use configuration and calibration software
  • Optional local high contrast OLED graphic display with joystick control
  • Two user-selectable digital communication interfaces (RS-232 and RS-485) are standard
  • The ability to create and store custom gas mixes with up to five different gases
  • Maximum measurable flow range 133% FS
  • No mounting sensitivity
