JC090 Compact Type Electromagnetic Flow Meter

Parameters of JC090 Compact Type Electromagnetic Flow Meter

Electromagnetic flowmeter is a kind of inductional instrument designed by Faraday’s law of electromagnetic induction to measure the flow of conductive media in the tube. It adopts the technology of insertion of a single chip to realize digital excitation and employs CAN local Fieldbus.

The electromagnetic flowmeter 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 the chemical industry, environmental protection, metallurgy, pharmaceutical, paper making, water supply, and removal, etc.

Besides measuring the flow of general conductive liquid electromagnetic flowmeter can measure the flow of liquid-solid mixed fluid, high-viscosity fluid and salt, strong acid, and strong alkali.

PERFORMANCES & FEATURES
  • Simple structures, firm, no movable parts, and long operation life
  • No intercepting fluid parts, no pressure loss, and fluid clogging
  • No mechanical inertia, quick response, and good stability apply in the automatic examination, adjustment, and control
  • Measuring accuracy not influenced by physical parameters such as style, temperature, viscosity, density, and pressure.
  • Employ Teflon or rubber liner and different combination of electrode material such as Hastelloy C,Hastelloy B, 316L,
  • Titanium and adapt the need of different mediums.
  • Supply many styles of flowmeters such as inline type and insertion type, etc.
  • Adopt EEPROM memory to measure operation data, safe and reliable protection of memory.
  • Integral type flowmeters and remote type flowmeters.
  • LCD backlight display with high clearness
Flow velocity range during measurement When measuring a clean medium, the economical flow velocity is 1.5~3m/s. When measuring a crystalloid solution, should increase flow velocity properly to 3~4m/s, which can self-clean, avoid adhesion and deposition, etc. When measuring abrasive fluid such as ore pulp, should reduce flow velocity properly to 1.0~2m/s in order to reduce abrasion on the liner and electrode. Over 7m/s is very few in practical application, and more than 10m/s is even rare. Selection of Liner Sheet 3
