Context
Components and working principle: A liquid level detector is composed of the
conductor outer jacket, liquid level detector, switch, and card pole. A liquid level
detector rises or drops as the liquid level changes due to the magnetism of the
liquid level switch, causing the reed switch chip in the specified position inside the
sensor detection pipe to move and send the contact on/off conversion signal to
control the liquid level detector.
The liquid level detector can be maintained only from the front.
