Why is my Endress+Hauser Liquiphant M FTL50 sporadically faulty switching?

Sporadic faulty switching of your Endress+Hauser Switch can occur due to several reasons. If there's thick, heavy foam, turbulent conditions, or foaming liquid, consider mounting the Liquiphant in a bypass. Extreme RFI (Radio-Frequency Interference) can be mitigated by using a shielded cable. For extreme vibration, try decoupling, damping, or turning the fork 90°. Water in the housing can cause issues, so ensure the cover and cable gland are tightly screwed. If you're using FEL52, an overloaded output could be the problem; reduce the load or cable capacitance.
