DM serial high frequency electromagnetic flowmeters are mainly used in high viscosity uniform medium such as detecting paper pulp, mud, cement slurry (containing fine particles), mortar, liquid that produces noise due to the physical reaction or electrochemical reaction or the medium affected by magnetic field around.
Characteristics
1) The measurement is not affected by the fluid density, viscosity, temperature and pressure change.
2) There are no components stopping flowing in the pipe; the pressure loss is small; no maintenance is needed.
3) The sensor adopts advanced machining process, which makes the meter have good ability against negative pressure.
4) It has double flow direction measurement and double direction quantum accumulating function.
