Tips: How to debug the float liquid level switch?

The float liquid level switch only needs to recalibrate the water level before your install it, and itself cannot be adjusted. Then you need to use a multimeter to measure the state of the float switch. It will be on and off near the waterline along with the water level, which means it is normal. Make sure that the installation is consistent with the water level of the heating equipment. For example, the level switch is generally attached to the water level line on the wall of the cylinder. Soak the switch in the tank and let it slowly sink, so that the water is gradually close to the identification line. The sound of the micro switch action will be heard when it is closest to the line.

The low level alarm is connected to the normally closed (NC), and the high level alarm is connected to the normally open (NO). The liquid level switch itself has more than two pairs of micro switches, respectively output two pairs of normally open and two pairs of normally closed contacts. In the application, it is usually “on the alarm”.
