The Fox Thermal FT3 mass flow meter and temperature transmitter measures two important process variables with a single instrument, providing isolated 4 to 20 mA and pulse outputs for flow rate, and a 4 to 20 mA pulse output for process gas temperature or a second flow rate output.
Direct mass flow measurement, exceptional low-flow sensitivity, fast response, and low maintenance requirements distinguish the Fox Model FT3. Virtually immune to changes in temperature and pressure, the flow meter delivers repeatable, accurate mass flow measurement under varying loads. It's rugged, no-moving-parts design is also ideal for high-vibration industrial environments, and enhanced EMI immunity makes it suitable for environments where electric motors, igniters or dirty power may affect instrument performance.
The Model FT3's CAL-V feature is an in-situ calibration routine that validates the flow meter's calibration accuracy by testing the functionality of the sensor and its associated signal processing circuitry. This innovative approach lets you validate instrument calibration in your pipe, at your process conditions, with just a push of a button. At the conclusion of the test, the meter will display a pass/fail message and the CAL-V data is saved in the meter for look-up at any time.
Unlike CAL-V, which may be performed in the pipe and at process conditions, Zero CAL-CHECK must be performed at zero flow to ensure a valid test result. Depending on the test selected (insitu or out of pipe), zero flow will either be compared to a customer-established field baseline or factory baseline.
View the FT3 calibration validation flyer for more information about the CAL-V and Zero CAL-CHECK features.

This product can be used in the following applications:
The Background: Our customer is a natural gas power plant seeking to replace the flow meters they use to measure the amount of natural gas used by the plant.
The Problem: The customer needs a highly accurate flow meter with hazardous area approvals. The don’t want to have to rework piping in order to install the new meter.
The Solution: We recommended the Fox Thermal FT3 mass flow meter which provides ±0.2% full scale accuracy and is available with a wide range of hazardous area approvals for use with natural gas. The FTY3 also includes built-in flow conditioners that eliminate the need for long, straight pipe runs making installation easy and reducing installation costs.
