The Fox Model FT2 ThermalGas Mass Flowmeter and Temperature Transmitter measures two important process variables in one rugged instrument. The Model FT2 measures gas flow rate in standard units without the need for temperature or pressure compensation. It provides isolated 4 to 20 mA and pulse outputs for flow rate, and a 4 to 20 mA output for process gas temperature. The pulseoutput is normally used for totalization.
An optional on-board 2 line x 16 character, backlit display is available to view flow rate, total, elapsed time, process gas temperature, andalarms. The display is also used in conjunction with the Configuration Panel to configure flowmeter settings, pulse output frequency scaling, pipe area, zero flow cutoff, flow filtering (damping), display configurations, diagnostics and high or low alarm limits.
The Model FT2 is available in both insertion and in-line models. The insertion meter is easily installed by drilling a ¾” hole in the pipe and welding on a ¾” NPT coupling. A Fox supplied compression fitting secures the probe in place. The inline model is available in ¼-inch to 6-inch sizes and includes built in flow conditioners that eliminate the need for long, straight pipe runs. The meter can be ordered with flange or NPT end connections.
Both models are supplied with 316 stainless steel wetted materials standardorHastelloy C-276 as an option. RS232 for connecting a Palm Handheld or computer is standard. Interfaceoptions include RS422/RS485-Modbus, Profibus-DP, DeviceNet or Ethernet Modbus TCP.
Fox has certified cleaning and bagging procedures for flowmeters to be used in oxygen applications.
