Level Measurement and level monitoring – Liquid level switches

Liquid level switches

Contec liquid level switches - also known as level switches or level limit switches - signal a specific, fixed liquid level. If the switch detects a certain liquid level - i.e. if the level exceeds or falls below the specified value, it emits a signal, for example a warning message.

The liquid or medium to be measured, the environments in which the switch is used and the position in which it is mounted determine the switch type. Contec liquid level sensors are divided into:

Applications e.g. in

Custom designs

Contec liquid level switches can be configured in many areas according to the customer's application, e.g. with:


Contec liquid level switches stand for:

Practical examples of level measurement
