The electromagentic KMU-20 flowmeters are suitable for liquid measuraments of any kind: dirt, abrasive, corrosive, with solid in suspension on condition that are conductibles (3microSiemens minimum).
The functioning is based on the well known Farady law and are almost insensible to the chemical-physic nature of the product (working temperature, viscosity, pressure) they don't have any part in motion and are hugely used wether for continuos type of measurement or for "batch dosing".
