Fox Thermal FT3 Mass Flow Meter & Temperature Transmitter

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.

CAL-V Performs Calibration Validation in your Pipe

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.

Zero CAL-CHECK Calibration Validation Feature

• Checks for build-up on sensor that could affect calibration
• Further validates the zero stability of the meter
• Checks thermal conductivity (heat transfer) repeatability of the sensor

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.
