Monitor and data log tank farm inventory from your PC. Install one TFT32 Transmitter at each tank with your choice of sensors including ultrasonic, pressure or 4-20mA from existing sensors (including flow, pH or any process variable). Connect up to 32 TFT32 Transmitters in a network and run TFS Tank Farm Supervisor PC software to display levels, monitor relay status and log tank levels. The system is reliable - TFT32 Transmitters and additional control relays continue to operate even without PC connection.
