Fox PowerPro Sensor™ and DDC-Sensor™ Explained

PowerPro SensorPowerPro Sensor™

Used in Fox Models FT2A and FT3, the Fox PowerPro™ Sensor, operates at a higher power level than other competitive thermal technologies, providing better response time and wider turndown. Compared to a typical Differential Pressure type flowmeter, as shown to the right, the PowerPro™ sensor offers better low flow or low end sensitivity. The PowerPro™ sensor also provides exceptional accuracy at high velocities - up to 50,000 SFPM air.




The Fox DDC-Sensor™ is a new state of the art sensor technology used in the Fox Model FT1 Thermal Gas Flow Meter. The DDC-Sensor™, a Direct Digitally Controlled sensor that is interfaced directly to the FT1 microprocessor for more speed and programmability. Like the PowerPro™ Sensor, the DDC-Sensor™ accurately responds to changes in process variables (gas flow rate, pressure, and temperature) which are used by the microprocessor to determine mass flow rate, totalized flow, and temperature.

In addition to measuring flow, the DDC-Sensor™ provides a technology platform for calculating accurate gas correlations. The FT1 correlation algorithms allow the meter to be calibrated on a single gas in the factory while providing the user the ability to select other gases in the Gas-SelectX® gas menu. Fox’s Model FT1 with its DDC-Sensor™ and state-of-the-art correlation algorithms provide an accurate, multi-gas-capable thermal gas flow meter.
