■Measuring Principles
Measuring range of the LD smart electromagnetic flowmeter determined on the basis of Faraday Low of Electromagnetic Induction: If lines of magnetic induction are cut through in magnetic field by conductive liquid. Based on the law, we install a pair of electrodes on both sides inside a pipe that runs perpendicularly to both the measuring tube axes and magnetic line of force, electromotive E will be generated between the electrodes.
When flux needs measuring, conductive liquid is let go on velocity V through a magnetic field that is perpendicular to the flow direction. With the conductive liquid running through, a voltage that is proportional to average flowing velocity is to be induced. The voltage signal induced can be detected by two or more electrodes that contacts the liquid and then transmitted to converter for intellectual processing before being shown in LCD display outputting stand end signals of 4~20mA or 0-1kHz.

In order to enable a reliable flow meter, Pls note the following installation requirements:
1. As far as possible to avoid ferromagnetic objects and equipment with strong magnetic fields(big electric machine, big transformer) is protect of the magnetic field sensor.
2. lt should be installed in the ventilation in the dry, avoid moist and stagnant water.
3. lt should be avoided solarization and rain, To avoid environment temperature higher than 60℃ and humidity more than 95%
4. Flow meter should be enough space around for easy installation and Maintenance.
5. Flow meter must be installed at the outlet of the pump. valve should be installed at downstream of the flow meter.
