Fox Thermal Instruments announced today the FM (U.S.), FMc (Canadian), ATEX (EU), and IECEx (Global) approvals of the Fox Model FT3 Thermal Mass Flow Meter & Temperature Transmitter.

The flow meter features many advanced features: CAL-V - an in situ calibration validation routine; infrared buttons - advanced programming buttons maintain integrity of enclosure; HART and RS485 Modbus - optional communication protocols; standard USB port - gain direct meter-to-PC connections; and FT3 View - software for configuring, graphing and logging data.

The FT3 was designed to be used in any pure or mixed gas application, in refineries, petrochemical plants, and natural gas gathering/processing plants. It is commonly used for flares, vent (flash) gas, and biogas applications. In addition, with its rugged-design, it is suited for heavy industrial applications in metals, paper, glass and ceramics.

Other FT3 features are dual 4 to 20mA outputs (one for flow and the second selectable for flow or temperature) and pulse output (pulses per unit/units per pulse). A basic insertion type uses the PowerPro Sensor to measure from 0.07 to 280 NMPS with a flow accuracy of ±1% of reading, ±0.4% of full scale. It can measure in over 25 selectable flow units and can be calibrated to continuously monitor the flow of air, compressed air, natural gas, biogas, mixed gases, and pure gases.

FT3 View allows easy adjustments to the meter configuration, evaluation of alarm conditions, collection of process data, and measurement viewing from your PC or control station. Moreover, this software can be used to initiate CAL-V -- and it automatically logs the results of each CAL-V test. If any regulatory submission is required, the software will generate a Calibration Validation Certificate for easy recordkeeping.

A USB connection port comes standard on the new Model FT3 which allows quick and easy access with a laptop. Communications options available are HART and RS485 Modbus.
