Endress+Hauser Levelflex FMP54

Levelflex M micropulse level transmitter for general measurement of overflow and interfacial level of liquid products. Stable and reliable in the case of unstable product surfaces and the presence of foam, as well as in the case of products with changing properties. Built-in memory module for data storage.

For high temperature and high pressure applications in the oil & gas, chemical and power industry.
