Fluid level monitoring
When the pools at a waste water treatment plant are filled to a constant level, this causes undefined states for the float switches (a “flutter state”).
The use of the timing relay with Function E (switch-on delay) delays the reading of the switch contact until the next usable measurement, and thereby prevents “flutter switching”.
– Minimisation of faulty triggering and maintenance costs
– Motor protection by reducing the number of unnecessary system starts
– Increased reliability
