DPC07 Series - Differential Pressure Mass/Volumetric Flow Controllers

DPC mass flow controllers multi-parameter and multi-gas functionality operate locally via optional OLED/Joystick interface, remotely via RS232/RS485 interface or by the optional Modbus RTU interface. High accuracy and resolution are achieved with the differential pressure sensor measuring pressure drop across a laminar flow channel, which is linearly proportional to volumetric flow rate and converted to mass flow using absolute pressure and temperature sensors.

These differential pressure mass flow controllers feature two programmable flow totalizers with batch processing mode (0.5% RD + 0.2% FS) standard accuracy, 200:1 turn down ratio and less than 150 ms response time.

User selectable local, analog, digital or program set point control, automatic zero adjustment (activated via local or communication interface), programmable SSR relay, programmable 0-5Vdc, 0-10Vdc, or 4-20mA analog inputs and outputs, user-programmable pulse output (via SSR) and extensive self diagnostics functionalities make the DPC a cost saving option when compared to acquiring and installing multiple application specific devices.

  • Simultaneously displays Mass Flow, Volumetric Flow, Pressure and Temperature.
  • Multi-Gas functionality: support for 90 different gases and gas mixtures.
  • User Defined Mixture functionality allows creation and storage of 20 custom gas mixtures with up to 5 different gases each.
  • Standard accuracy ± (0.5% RD + 0.2% FS).
  • 200:1 turn-down ratio.
  • Two programmable mass flow rate totalizers.
  • User programmable mass flow rate Pulse Output (via SSR).
  • Low high or range flow, temperature and pressure alarms
  • Extensive Self Diagnostics with status LED or OLED indication.
  • Three user selectable analog input and output interfaces are standard: 0-5Vdc, 0-10Vdc, 4-20mA.
  • Two user selectable digital communication interfaces (RS-232 and RS-484) are standard.
  • Optional Modbus RTU network interface with isolated RS-485 transceiver.
  • User programmable solid state relay with latch option.
  • Universal 12-26Vdc power supply input for DPC07, DPC17, DPC37 and DPC47. 24-26Vdc for DPC57, DPC67 and DPC77
  • Local high contrast OLED (optional) graphic display with joystick control.
  • Free, easy-to-use configuration and calibration software (RS-232/RS-485).
