Description low cost 4-20mA electromagnetic liquid diesel oil flow meter

Smart electromagnetic flowmeter LD series is oriented for conductive liquid with conductance higher than 5us/cm, it can be used to measure the volume flow of conductive fluid in a closed pipeline.lt is composed of sensor and converter and two versions are available : Compact version and separate version. It is widely applied in the flow measurement and control in the fields of chemical and petroleum industry, metallurgy industry, water and waste water, agriculture and irrigation, paper making, food and beverage industry and pharmaceutical industry.
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 elctrodes 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 outputing standend signals of 4~20mA or 0-1 kHz.
