Product Details

1、 The LKJ type formaldehyde metal tube float flowmeter has the characteristics of simple structure, reliable operation, wide applicability, accurate measurement, and easy installation. There are two types of metal rotor flow meters with high temperature and high pressure resistance: ordinary and corrosion-resistant. The above two types are divided into on-site indication type and electric remote transmission type, ordinary flow sensor, instrument material (1Cr18Ni9Ti), and anti-corrosion type (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 the corresponding flowmeter.
