Liquid Level

Benefits of Liquid Level and Remote Seals

Measuring the level of liquid is one of the more essential measurements in a process. Incorrect measurements can cause tanks to overflow creating potential safety or environmental problems; or, low levels can cause pump damage. Even wrong intermediate levels can result in an inferior quality product. Whether the application is for monitoring or control, the liquid level indicator needs to be accurate, reliable, and quick.

What is Liquid Level?

Liquid tank level is a basic measurement in process plants. In many industrial processes, it is vital to maintain precise liquid levels in tanks. Inaccurate measurements can lead to inventory control problems, cause a pump failure or vessel overflow. That can result in product loss, environmental contamination, or a safety hazard.
