UMD-99 Series Static Pressure Level Transmitter

More Suitable for All Kinds of Water Level Measurement

Utilizing the principle that liquid static pressure is directly proportional to the liquid height for measuring liquid level. Equipped with a dry ceramic capacitor imported from the United States, featuring high stability and reliability, or a temperature-compensated and isolated diaphragm-type diffused silicon pressure sensor. Economical pricing, simple installation, and usage. Can be inserted from the top.

Model Introduction
