Recently, we received many consulting calls, mainly asking what kind of liquid level measuring instrument is better for the sewage tank. The following is some information collected for your reference.

First, let us look at the environment: Domestic sewage or industrial sewage.

Generally, manufacturers require non-contact measurement if industrial sewage contains heavy metals and so on. If there are not many impurities in domestic sewage, input type can be used. If there are too many impurities, non-contact type is better. Sewage treatment should also have a recycling process. For example, input type is generally used for organic water liquid level measurement which can be collected.

In short, pay attention to the following points:

1： There are many impurities settling , choose non-contact type

2： Highly corrosive, choose non-contact type

3： Foam ozone tank under environmental pressure, choose input type

Generally speaking, the non-contact type is ultrasonic technology, which can be selected according to the site.
