Aalborg DPM series digital multi-parameter mass flow meters provide accurate measurements of mass and volumetric flow rates, pressures and temperatures of process gases. DPM mass flow meters incorporate multi-parameter multi-gas functionality which allows users on site to select up to 30 different gases locally via optional OLED/Joystick interface, or remotely via RS232/RS485 interface, or optional Modbus RTU interface.

DPM flow meters support two programmable flow totalizers, low, high or range flow, temperature and pressure alarms, automatic zero adjustment (activated via local or communication interface), programmable SSR relay, programmable 0-5 Vdc, 0-10 Vdc or 4-20 mA analog outputs, user-programmable pulse output (via SSR), and extensive self-diagnostics.

The instruments feature multi-parameter/multi-gas functionality with support for 90 different gases and gas mixes. "User Defined Mixture" functionality allows creation and storage of up to 20 custom gas mixes with up to 5 different gases each. Standard accuracy is ± (0.5% RD + 0.2% FS) with 200:1 turndown ratio and 10-20 ms response time.

Used in a variety of industries including scientific and analytical applications, bioreactors and surface depositions, gas sampling, manufacturing and metrology activities. Significant savings are apparent comparing the cost of a single DPM meter embodying these features with that of acquiring and installing multiple, application-specific devices.
