Model FT2 Thermal Mass Flow Meter

The Fox Model FT2 is a state-of-the-art thermal flow meter and temperature transmitter. It offers direct mass measurement of gases in Standard Cubic Feet per Minute (SCFM), Normal Cubic Meters per Hour (NM3H), Kilograms per Hour (Kg/Hr), and other mass units. With the Fox Model FT2 meter variation in process, pressure or temperature is not an issue. These mass flow meters are constructed with two isolated 4 to 20 mA outputs (one for flow and one for temperature) and one pulse output (for flow) are standard. Each are capable of measuring low velocity flow better than any other technology. This results in a wide measurement range and turndown: 100 to 1 typical; higher in many applications.

Insertion type meters substantially reduce installation cost and can be installed in pipe sizes from 1-1/2" and all the way up to large ducts. Other features include:

• The Fox Power Pro Sensor is operated at a higher power level than competitive models, resulting in improved response time and wider turndown.
• The sensor is all-welded and is constructed of grade 316 stainless steel or Hastelloy C276 as an option. There are no moving parts.
• The FT2 is field-programmable using the display and configuration panel or a Palm PDA.
• Communications options include RS232 for connecting a Palm Handheld or computer; RS 422/RS485-Modbus, Profibus-DP, DeviceNet and Ethernet.

Inline meters are available for 1/4" to 6" pipes and have built-in flow conditioners that reduce the requirement for long straight pipe upstream and down stream.
