TLC-26
Pressure-based
Tank Level Controller


Uses Dynamic Pressure Stabilization^TM and Transient Pressure Integration^TM to monitor system pressure and control the pumps at a pump station. No equipment needed at the tank. Controls pumps by comparing system pressure with Pump-start / Pump-stop pressure settings. Alarm outputs may be connected to an optional automatic telephone dialer or telemetry system.

The following menu-selectable options are available from the display and keypad:

• Pressure transmitter range (5.0 PSI up to 500 PSI)


• Display either system pressure in PSI or tank level in feet


• Pump-start / Pump-stop pressure settings with time delays


• Dynamic pressure offsets for each pump


• Pump-start / Pump-stop control lockout time delay


• Pump alternation and Pump-start and Pump-stop sequencing in two pump systems


• Pump Failed-to-start alarm output


• High and Low discharge pressure shutdown and alarm output


• Low suction pressure shutdown and alarm output


• Phase-loss input with system shutdown and alarm output


• Easy-to-use, menu-driven setup screens -- no need for a setup computer
