Features

  • High Accuracy of +-2% of reading (or 0.05 SLPM)
  • Linearized Analog Output
  • Temperature Compensating
  • Microcontroller Design for Customization

Kelly Pneumatics, Inc. offers a Gas Flow Sensor for high volume flow rates of Air and Oxygen. The sensor automatically compensates for temperature changes in the measured gas and outputs accurate readings of mass flow and temperature via analog voltage.

The Gas Flow Sensor outputs flow for Air and Oxygen from 0-300 SLPM, with an accuracy of 2% of reading, and offers a flow sample response time of 2 milliseconds. An internal microprocessor measures signals from an internal thermistor and hot wire anemometer to linearize flow measurements, and allows for numerous settings for flow and temperature output readings. The compact, lightweight design is perfect for OEM applications, especially medical, semiconductor, and gas analyzer products.
