Aalborg Instruments' DPC series precision digital mass flow controllers provide accurate and stable control of mass flow rate for process gases. They incorporate multi-parameter, multi-gas functionality allowing 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 .

The DPC series supports an impressive 90 different gases and gas mixes, plus "User Defined Mixture" functionality that 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 less than 150 ms response time.

DPC flow controllers support various functions including user selectable local, analog, digital or program set point control, two programmable flow totalizers with batch processing mode, LOW, HIGH or RANGE flow alarms, 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.

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 cost of owning and installing multiple application-specific instruments is significantly reduced with this single device.
