2910 Float & Tape Transmitter
The 2910 Float & Tape Transmitter (FTT) provides data from the tank side to the control room for use in inventory management volumetric calculations. It is also able to integrate a single temperature sensor and provide inputs and outputs for basic automation and control.

Absolute Accuracy and Reliability
The 2910 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. What’s more, the encoder requires no service, no battery back-up and contains no parts that can wear out over time.
Automation and Control
The 2910 FTT provides the first steps to automation and control. It can activate alarms or relays using discrete inputs, SPDT cam-operated outputs and software-driven contact outputs.
On Your Tank
The 2910 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®, Mark/Space, Tankway).
Simplicity If Needed
If a simple level alarm system is needed the 2910 FTT can be ordered with only limit switches. This configuration does not require power at the unit.
Rated For Safety
The 2910 FTT is third-party approved for use in explosion hazardous areas, just as you would expect.
The 2910 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.
