Product Details
FLDC series 4-20mA electromagnetic flowmeter is a fully intelligent flowmeter developed by our company with the most advanced technology at home and abroad. It has high measurement accuracy, high reliability, good stability and long service life. In the process of designing product structure, material selection, manufacturing process, production assembly and factory test, we are very meticulous and strict. We have also designed a set of the most advanced production equipment and flow calibration device specially for electromagnetic flowmeter, so as to ensure both software and hardware. Long-term high quality of certificate products
Output signals
·4-20mA output:suitable for long-distance analog signal transmission; ·Frequency/pulse output:used for meter calibration and accumulative flow output;
·RS485 communication:It can support networking of multiple electromagnetic flowmeters and long-distance data transmission; Users need to select output signals according to actual conditions and supporting equipment.
Selection of grounding ring
· Grounding ring is used to ground the measured medium to improve the stability of the electromagnetic flowmeter measurement. Because the grounding ring needs to be in contact with the measured medium, there is a possibility of corrosion and wear of grounding ring, which needs to be replaced periodically.
· Instead of using grounding ring, FLDC series electromagnetic flowmeter has adopted grounding electrode to guarantee long-term stability of grounding and high accuracy. If the stray current is too large to guarantee the normal measurement of the electromagnetic flowmeter, such as the leakage current of the electrolytic cell along the electrolyte,a grounding ring would be recommended to be used.
· Some small-caliber electromagnetic flowmeters have only two electrodes, and users can choose double grounding rings according to site requirements.
· When installing the grounding ring, the grounding ring needs to be put on the right position to avoid affecting the flow field of the measured medium.
