Liquid level switches | Choosing the right level switch
There are several types of technology used for level switches, and some of them are also used for level sensors. The different types of technology available are more or less suitable according to the type of product you want to measure the level for, whether it is a liquid, a pasty product or a solid in bulk. The main technologies used for level switches are: Float level switch: a float follows the movement of the surface of a liquid and triggers a switch. ...
