The HPM410-F flange cage liquid level transmitter is a fully sealed submersible device that utilizes a high-quality and highly stable pressure sensor as the sensing element. This product is designed with an oversized flat diaphragm pressure sensing structure and a robust flange cage protection structure, making it suitable for measuring liquid levels in environments with silt, mud, and sedimentation. Moreover, it effectively guards against solid floating objects and suspended solids, preventing clogging.

The outer casing of this product undergoes a fully welded process, ensuring reliable sealing at each connection point through multiple design features. The internal potting process guarantees a long operational lifespan. The upper section of the product is equipped with NPT threads, providing flexibility for secure attachment to pipes or conduits. Additionally, the entire device can be easily transported using the lifting ring.
