Electromagnetic Water Flow Meter, seawater magnetic flow transmitter, heat meter
Description
The electromagnetic heat meter utilizes the relationship between flow rate and cooling effect for direct measurement of mass flow. With no moving parts and minimal invasiveness, thermal flow meters provide a highly repeatable, accurate, low cost, easy to install solution for flow measurements and calculating energy consumption. We provide flow meters suitable for applications in pipes and ducts, from DN10 to DN2000.
Our magnetic heat meter works on Law of Faraday's electromagnetic induction. We've owned our own patents: ZL2010 20145263.9 and ZL2011301682. It consists of: flow measurement, heat integrating unit and temperature sensor. The magnetic meter is designed to improve the accuracy and reliability of trade settlement in HVAC, centra air conditioning system
Measure theory
The electromagnetic flowmeters, can detect flow by using Faraday's Law of induction. Inside a magnetic flow meter, there is an electromagnetic coil, that generates a magnetic field, and the electrodes that capture electromotive force (voltage).

How to use the magnetic flow meter
The ElectroMagnetic flowmeters measure the velocity of conductive liquids in pipes, such as water, acids, caustic, and slurries. Magnetic flowmeters can measure properly when the electrical conductivity of the liquid is greater than approximately 5μS/cm. Be careful because using magnetic flowmeters on fluids with low conductivity, such as deionized water, boiler feed water, or hydrocarbons, can cause the flowmeter to turn off and measure zero flow.
