Product Description
Product Description
Electromagnetic flowmeter working principle
Faraday's Laws of induction form the basis for the magnetic water flow meter which states that a voltage is generated in a conductor as it moves through a magnetic field.
This principle is applied to a conductive fluid which flows through the meter tube perpendicular to the direction of the magnetic field (see Schematic).
UE ~ B · D ·V
The voltage induced in the fluid is measured by two electrodes located diametrically opposite to each other.
This signal voltage UE is proportional to the magnetic induction B, the electrode spacing D and the average flow velocity v. Noting that the magnetic induction B and the electrode spacing D are constant values indicates that a proportionality exists between the signal voltage EU and the average flow velocity v. From the equation for calculating the volume flowrate* )UE ~ qv, it follows that the signal voltage is linear and proportional to the volumetric flowrate.
Product Parameters
Main Features
1). With simple structure ,the flow meter is of high reliability.
2). The wide range of the nominal bore is suitable for all the pipe size between DN6 and DN3000.
3). Measurement is independent of fluid density ,viscosity ,humidity ,temperature pressure and conductivity.
4). The sensor with advanced processing technology and liquid airproof is of long natural life and of nice resistance to shaking leakage.It guarantees the instrument good precision and stability .
