2920 Float & Tape Transmitter
The 2920 Float & Tape Transmitter (FTT) provides data from the tank side to the control room for use in inventory management applications. It accurately converts mechanical level measurement from the connected tank gauge, integrates temperature and HART devices, and provides digital inputs and digital outputs for the indication of alarms or drive relays.

A digital display with capacitive touch control interface provides inventory information at the tank side and configuration of the transmitter for all connected devices. Each parameter, such as communications, baud rate, unit address, etc., is easily configured using the touch screen display.
Absolute Accuracy and Reliability
The 2920 FTT utilizes an absolute capacitance encoder and precision direct-drive gearing to accurately convert the mechanical level measurement from the connected tank gauge – the most accurate encoder technology on the market today. Furthermore, the encoder requires no service, no battery back-up and contains no parts that can wear out over time.
On Your Tank
The 2920 FTT is easy to install. It mounts directly to most mechanical tank gauges, (Varec, GSI, L&J, Sakura) and integrates into existing tank gauging communication loops (MODBUS®, Biphase Mark, Mark/ Space and Tankway).
Complete Tank Gauging System
The 2920 FTT integrates ancillary equipment, and sensors, and provides the first steps to automation and control. It supports up to 4 HART devices and provides an on‐board 3‐wire RTD temperature input. It can activate alarms or relays using analog and digital inputs/outputs, SPDT cam-operated outputs and software-driven contact outputs.
Training and Support
The 2920 FTT is available to ship today. Every transmitter is supplied with detailed user instructions, but sometimes you need to see how it’s done. That’s why we also have a YouTube channel with basic how-to-videos. If you need direct support, we offer standard training and service programs that we tailor to your staff, and your facility.
