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.
Key Features:
Industrial Applications:
The free FT2A View™ software from Fox Thermal is a great way to connect your PC or laptop to the FT2A in order to access the meter settings in a quick and easy way. This software offers:
Note: For FT2A View™ software to function properly, please be sure to have a working version of Microsoft® Office installed on the PC before installing FT2A View™.
USB Driver and the Fox Thermal FT2A View™ Software
A USB driver is needed for FT2A 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.
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:
