The battery-powered electromagnetic flowmeter is specially designed for the water industry to meet the requirements of urban water supply and ensure accurate calculation of water charges. SCLDE DC batteries electromagnetic flowmeter and called the intelligent type electromagnetic flowmeter, low power consumption, power is supplied by batteries can be the scene display and output pulse equivalent, continue to work up to three years, and applied to the base station of wireless communication network system, build a communication base station in the center of the region, covering radius of 1000 meters, can be directly through the GPRS/CDMA mobile communications network for data communications.

Battery power electromagnetic flowmeter specially designed sensor excitation system and high-performance lithium battery power supply system, electromagnetic flow sensor is made use of Faraday's law of electromagnetic induction, when conducting liquid along the measuring tube in the alternating magnetic field in a direction perpendicular to the magnetic field lines, conducting liquid cutting lines of magnetic force induced potential, with the sounding pipe axis and the magnetic field lines are perpendicular to the pipe installed on a pair of electrodes, the electrode of the induction electric potential detection. The induced potential is proportional to the flow, and the measured induced potential leads to the flow through the sensor. This flow signal (induced potential) input converter is amplified into a digital signal proportional to the flow signal, thereby achieving flow measurement.
