LMF® – LaminarMasterFlow®

High-precision flow measurement of gas and air

The EP LMF® – LaminarMasterFlow® is a complete system for high precision flow measurement of gas and air (volume and mass flow). The LMF® system consists of a flow processor, a Laminar Flow Element (LFE) as measuring section, a cable set and a sensor set.

Different types of flow processors, diverse measurement accuracies, a big range of Laminar Flow Elements in different sizes and some options can be selected application specific and allow a variable system configuration.
