Aalborg DPM Multi-Parameter Thermal Mass Flowmeter

High Qiality Thermal Mass Flow Meters | Affordable Prices

General description

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 include multi-parameter multi-gas functionality that allows users to select up to 30 different gases locally via the optional OLED/Joystick interface on-site or remotely via the RS232/RS485 interface or optional Modbus RTU interface.

Design Features

  • Multi-Parameter Measurement Function: Mass Flow, Volumetric Flow, Gas Pressure and Temperature.
  • Multiple Gas Measurement Function: Support for 90 different gases and gas mixtures.
  • The "User Defined Mixture" function is a high precision product that allows you to create and measure up to 20 custom gas mixtures, each containing up to 5 different gases.
  • Fast response time (< 20ms)
  • Standard Precision ± (0.5% RD + 0.2% FS).
  • Wide Measurement Range Ratio as 200 : 1.
  • Two programmable mass flow rate collectors.
  • Preset Alarms for High, Low or Instantaneous Flow for Mass Flow, Temperature and Pressure.
  • Pulse for user-programmable mass flow (via SSR).
  • Comprehensive Self-status notification via status LED or OLED indicator.
  • All 3 user-selectable analog output interfaces are standard: 0-5Vdc, 0-10Vdc, 4-20mA.
  • Two user-selectable digital communication interfaces (RS-232 and RS-485) are standard.
  • Optional Modbus RTU communication interface with isolated RS485 transceiver.
  • User programmable solid state relay.
  • Universal 9-26 Vdc power supply
  • High-contrast OLED (optional) graphic display.
  • Free, easy-to-use configuration and calibration software (RS-232/RS-485).
