Electromagnetic flowmeter is only applicable to measure the flow of conductive liquid, which is wide used in water supply, sewage water measuring, industry chemical measuring etc. The remote type is with high IP protection class and can be installed in different locations for the transmitter and converter. Output signal can pulse,4-20mA or with RS485 communication.
Features
Accuracy: ±0.5% (Flow speed > 1m/s)
Reliably: 0.15%
Theoretical value: Water: Min. 20μS/cm; Other liquid: Min. 5μS/cm
Recommended value: ＞30μS/cm
Mag meter works based on Faraday's law, and measure conductive medium with conductivity more than 5 μs/cm and flow range from 0.2 to 15 m/s. An Electromagnetic Flowmeter is a volumetric Flowmeter that measures the flow velocity of a liquid through a pipe.
The measurement principle of magnetic flow meters can be described as follows: when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v:
E=K×B×V×D
Where:
E－Induced electromotive force
K－Meter constant
B－Magnetic induction density
V－Average flow speed in cross-section of measuring tube
D－Inner diameter of measuring tube
Introduction
Noted: the product strictly prohibited to be used in explosion-proof occasions.
Application
Electromagnetic flowmeters have been used throughout industries for more than 60 years. These meters are applicable for all conductive liquids, such as: Domestic water, industrial water, raw water, ground water, urban sewage, industrial wastewater, the processed neutral pulp, pulp slurry, etc.
