Digital flow controller by Teledyne gives users fast response times

The HFC-D-302 digital flow controller by Teledyne

Teledyne Hastings Instruments partners with Durham Instruments to supply great industrial measurement devices in Canada, such as the Digital 300 Vue series of thermal mass flow meters and controllers. These units measure mass flow accurately, with no corrections or compensations for gas pressure and temperature. One example: the HFC-D-302A/B digital flow controller.

This unique instrument includes a precision solenoid proportional control valve that is configured and tested on the user’s flow rate, gas, and pressure conditions.

For leak testing and more

The HFC-D-302A/B is recommended for many industrial applications, such as leak testing, high-purity gas delivery, thin film deposition, gas blending, pharmaceuticals, fuel-cell research and development, environmental monitoring, and medical research. The Durham Instruments team deems this digital flow controller suitable for use in general manufacturing, aerospace, automation, education, food processing, the military, packaging, power, energy, and transportation.

All products in the Digital 300 Vue series have thermal-based mass flow sensors with exceptional linear response to changing flow rates. These sensors offer fast response times with precisely tuned electronics. The HFC-D-302B model has an optional touchscreen display that enables viewing and control of flow rates directly through the instrument. The main screen displays flow rate and set point, units of measure, valve mode, and change in flow over time and allows access to menus that enable quick configuration of the unit for varying requirements.

Among the other features and advantages of the HFC-D-302A/B digital flow controller: flow ranges from 0-5 sccm to 0-25 slm (N2 equivalent); accuracy of plus or minus (½ a per cent of reading plus 1/5 a per cent of full scale); all-metal seals; an HFC-D-302 valve with Kalrez seat; a USB port; 0-5 VDC, 0-10 VDC, 0-20 mA, or 4-20 mA I/O; RS232/RS485; typical settling time of one to two seconds; Status LEDs; totalizer; large-diameter sensor tube; operating pressure exceeding 500 pounds per square inch; NIST traceable calibration; high linearity; and digital extended range.
