Selection of Metal Rotor Flowmeter-EEWORLD

Collect

The metal rotor flowmeter has the characteristics of simple structure, reliable operation, wide application range, accurate measurement, easy installation, etc. It is resistant to high temperature and high pressure. SKLZ series metal rotor flowmeters are available in ordinary and anti-corrosion types. The above two types are divided into field indication type (SKLZZ-) and electrical remote transmission type (SKLZD-), ordinary flow sensor, instrument material is (1Cr18Ni9Ti), anti-corrosion type is (1Cr18Ni9Ti) lined with PTEF.

　　If the medium measured by the metal rotor flowmeter contains ferromagnetic particles, a magnetic filter should be installed at the inlet of the flowmeter. Its material should be the same as that of the corresponding flowmeter.
