Introduction
Magnetic flow meters can realize local indication and output electrical current signal of 4-20mA which can be used to record, adjust and control. Electromagnetic flow meters are widely used in industrial sectors such as chemical industry, environmental protection, metallurgy, pharmaceutical, paper making, water supply and removal etc.
Besides measuring flow of general conductive liquid electromagnetic flow meter can measure flow of liquid-solid mixed fluid, high-viscosity fluid and salt, strong acid and strong alkali.
Features
1. Simple structures, firm, no movable parts and long operation life.
2. No intercepting fluid parts, no pressure loss and fluid clogging.
3. No mechanical inertia, quick response and good stability, application in automatic examination, adjustment & controlling.
4. Measuring accuracy not influenced by physical parameters such as style, temperature, viscosity, density and pressure.
6. Supply many styles of flow meters such as inline type and insertion type, etc.Adopt EEPROM memory to measure operation data, safe and reliable protection of memory.
7. High pressure sensor with PFA liner is resistant to high pressure and negative pressure, and available to chemistry and corrosive solution.
8. It is applicable not only to general process, but also in tough applications such as mining, papermaking, pastry, etc.
