Aalborg Instruments DPC series precision digital mass flow controllers

Aalborg Instruments’ DPC series precision digital mass flow controllers provide stable control of the mass flow rate of process gases. Inherent simultaneous displays of mass flow, volumetric flow, pressure and temperature parameters promote applications in a variety of industries such as scientific and analytical applications, bioreactors and surface depositions, gas sampling, manufacturing and metrology activities.

The precision digital mass flow controllers incorporate multigas functionalities allowing users on site to select up to 30 different gases locally via the optional OLED/joystick interface or remotely via the RS232/RS485 interface or optional Modbus RTU interface.

The flow controllers support various functions, including: user-selectable local, analog, digital or program set point control; two programmable flow totalisers; 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 inputs and outputs; user-programmable pulse output (via SSR); and extensive self-diagnostics functionality.
