FOX – FT1 Mass Thermal Flowmeter
Offering you the f lexibility to monitor multiple gas types at the push of a button, rotate the housing as needed for tight installations, and configure meter settings from advanced software, the FOX Model FT1 thermal mass f low meter and temperature transmitter can be used in a large variety of industrial and commercial gas f low measurement applications.
Fox Thermal Flow Meters use a constant temperature differential (constant T) technology to measure mass f low rate of air and gases. The thermal mass f low sensor consists of two Resistance Temperature Detectors ( RTD’s).
The Reference RTD measures the gas temperature. The instrument electronics heat the mass f low sensor, or heated element, to a constant temperature differential (constant T) above the gas temperature and measures the cooling effect of the gas f low. The electrical power required to maintain a constant temperature differential is directly proportional to the gas mass f low rate. The microprocessor linearises this signal to deliver a linear 4 to 20 mA signal.
