Introduction

For low-viscosity fluids in dosing and filling systems

 

The LFM micro-flowmeter is suitable for low-viscosity fluids in dosing and filling applications of all kinds. Its measuring element is based on the principle of a double ring piston meter. Thanks to the low pendulum mass and minimal frictional losses, the LFM responds to even the smallest volume flows. Only high-grade stainless steel that even withstands corrosive media is used in the production of the micro-flowmeter. The high-precision measuring element and extremely tight production tolerances of the single components minimize leakage and thereby guarantee good linearity and reproducibility of the LFM.
