(A+E-81F) Water Intelligent Electromagnetic Flow Meter

(A+E-81F) water intelligent Electromagnetic Flow Meter
Magnetic flowmeters use Faraday's Law of Electromagnetic Induction to determine the
Flow of liquid in a pipe. In a electromagnetic flowmeter, a magnetic field is generated and
Channeled into the liquid flowing through the pipe. Following Faraday's Law, flow of a
Conductive liquid through the magnetic field will cause a voltage signal to be sensed by
Electrodes located on the flow tube walls. When the fluid moves faster, more voltage is
Generated. Faraday's Law states that the voltage generated is proportional to the movement
Of the flowing liquid. The electronic transmitter processes the voltage signal to determine
Liquid flow.
In contrast with many other flowmeter technologies, magnetic flowmeter technology produces
Signals that are linear with flow. As such, the turndown associated with magnetic flowmeters
Can approach 20: 1 or better without sacrificing accuracy.
Features:
1) The flow measurement will not be impacted by changes of the density, viscosity,
Temperature, pressure and conductivity of liquid, and the induced voltage signal of
Sensor has linear relationship with flow rate, so the measurement accuracy is very high.
2) There is no baffles within the measuring pipes, so there is no additional pressure loss
And there is no moveable parts within the measuring pipes, so the service life of the
Sensor is extremely long.
3) The only part of sensor that contacts the measured liquid is the lining and the electrode.
As long as you choose the proper electrode and lining material, the product can be
Anti-corrosion and wear-resistance.
4) This converter adopts the latest and most advanced single chip (MCU) and SMT internationally,
And it has the advantages of reliable performances, high accuracy, low power comsumption,
Stable components, and convenient parameter setting. Click on the LCD to indicate the
Accumulated flow rate, instantaneous flow rate, flow velocity and flow percentage etc.
5) Using the two-way measurement system, to measure the positive flow and the negative flow.
To make sure that the product performance can remain stable in a long period of time, the
Product adopts special production process and high-quality material.
This Electromagnetic Flowmeter can be used to measure the volume flow rate of conducting
Liquid and seriflux in closed pipes, such as pure water, sewage, all kinds of acid-alkali-salt
Solution, slurry, pulp, paper pulp and food liquids.
