Foam and Water Tank Level Control System with Electroforce EFC39
1 piece EFC39-Full Control Unit and 2 pieces 250 mBar pressure sensors with 4-20 mA output are used in the system. The system is economical as the liquid level of 2 tanks can be controlled with a single controller.
LED Indicators
Liquid levels are shown with LED indicators connected to a total of 10 indicator outputs, 5 for each tank. All indicator outputs are driven proportionally with PWM, which allows the light intensity to be adjusted. By reducing the warming caused by the constant activation of the indicator lights, it also extends the life of the indicator LEDs.
Warnings and Calibration
Liquid level calibrations and calibration of proportional outputs can be done with digital inputs without the need for a computer.
- 2 digital outputs, 1 for each tank: active when the level drops below 10% or goes above 105%. An audible warning can be connected to these outputs.
- When the liquid level drops below 10%, the first level LED continuously flashes and alerts the user visually.
- When the liquid level rises above 105%, all level LEDs flash and notify the user visually of the overload.
- These checks are done separately for both tanks.
