The LFM is a pd flowmeter for all kinds of low-viscosity fluids, e.g. in batching and filling applications. It facilitates the measurement of extremely low flow rates from 5 cs/min upwards. The heart of the internal construction is a double ring piston. Thanks to the low mass of the piston and minimum frictional loss, the LFM will respond even to extremely low flow volumes.

In addition, the piston principle minimizes leakage and guarantees for a good linearity and repeatability.

The LFM 10 is compact and has a low weight of only 650g incl. pickup. Nevertheless, it is made from stainless steel like all KEM flowmeters. A filter is supplied with each LFM.
