Electromagnetic flowmeter

Overview

Intelligent electromagnetic flow meter is a kind of flow meter with high accuracy and reliability. It is used to measure the volume flow of liquid and slurry in closed pipelines, and is widely used in power, petroleum, chemical, coal, metallurgy, minerals, paper making, water supply and drainage, food, medicine and other industries.

Scope of application

Chinese and English display intelligent converter adopts 16-bit embedded microprocessor. Full digital processing, with two-way flow measurement function, instantaneous flow and positive and reverse accumulation and difference accumulation, used to measure the volume of conductive medium such as fresh water, sewage, acid, alkali, salt solution or liquid-solid two-phase fluid flow.

Features

  • Flow measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.
  • There are no obstructing flow parts in the measuring tube, no pressure loss, and low requirements for the straight pipe section.
  • The converter adopts LCD backlight display, which can make the degree easier under direct sunlight or in a darkroom.
  • Set parameters by touching the infrared ray button, which can be safely set without opening the cover of the converter in harsh environments.
  • The flow meter is a two-way measurement system with three integrators: forward total, reverse total and difference total; it can display forward and reverse flow and has multiple outputs: current, pulse, digital Communication, HART.
  • The converter has self-diagnostic alarm output, no-load detection alarm output, flow upper and lower limit alarm output, batch processing control and other functions.
  • Not only can be used for general process detection, but also suitable for the measurement of ore pulp, paper pulp, and paste liquid.
  • The high-pressure electromagnetic flowmeter sensor adopts PFA meshing lining technology, which is resistant to high pressure and negative pressure, and is specially used in petrochemical and mineral industries.
  • Explosion-proof instruments can be used in corresponding explosion-proof places.
