Thermal mass flow meter FT2A from FOX THERMAL INSTRUMENTS

The Fox Model FT2A, winner of both the 2014 Flow Control Innovation Award and the Processing Breakthrough Product Award, is the most widely versatile Thermal Gas Mass Flow Meter on the market today.

The Model FT2A has a large selection of communication protocol options available intrinsically (without any other equipment). Options include: BACnet MS/TP, RS485 Modbus RTU, Profibus-DP, DeviceNet, or Ethernet Modbus TCP.

The Model FT2A measures gas flow rate in standard units (SCFM, NM³/hr, LBS/HR, KG/HR & many more) without the need for temperature and pressure compensation. See the Features/Benefits section below to explore all that the FT2A can offer your application.

A free software tool – FT2A View™ - is available for the Model FT2A that allows the user to connect to and configure the FT2A using a PC or laptop.
