The Model FT3 was designed with our oil and gas customers in mind. This meter is Quad O (OOOO) compliant and is perfect for use in flare gas applications along with other fuel gas measurement.
Key Features:
Applications:
The free FT3 View™ software from Fox Thermal is a great way to access the meter settings directly by connecting the FT3 to a PC or laptop using a USB cable. View or change the meter settings with a simple click of the mouse. The FT3 software offers:
Note: For FT3 View™ software to function properly, please be sure to have a working version of Microsoft® Office installed on the PC before installing FT3 View™.
USB Driver and the Fox Thermal FT3 View™ Software
A USB driver is needed for FT3 View™ to run. If the USB drive does not install automatically, you will need to download it by following this link. Instructions are included on how to install it correctly.
The CAL-V™ and Zero CAL-CHECK® tests are used for Calibration Validation on the Model FT3. These tests do the following:
Use this test according to the manufacturer’s instructions in order to validate the calibration of the meter.
Flow meter accuracy is often dependent on achieving a uniform flow profile near the center of the pipe. Distortion and swirl are disturbances in flow that can be remedied either by extending the length of space between the cause of the disturbance and the sensing element (increasing straight pipe runs) or by adding a flow conditioner to correct the disturbance. Flow conditioners installed upstream of flow meters reduce the need for long, straight pipe runs. Common Features for Fox Thermal FC20 Flow Conditioner:
