Functional analysis of LDCK-50 electromagnetic flowmeter

LDCK-50 electromagnetic flowmeter is a flow meter with high precision, high reliability and long service life. It can be used in every link of the process of product structure design, material selection, process formulation, production assembly and factory testing. Shanghai Automation Instrument No. 9 Factory They are very meticulous and have also designed a set of production equipment and flow control devices for electromagnetic flowmeters by themselves, so as to ensure the long-term high quality of the products in terms of software and hardware. The electromagnetic flowmeter is specially designed with a Chinese LCD display with backlight and wide temperature. It is fully functional and practical, with intuitive display and easy operation. It can reduce the inconvenience caused by the English menu of other electromagnetic flowmeters. In addition, we designed a 4-6 multi-electrode structure to further ensure the measurement accuracy and eliminate the need for a grounding ring at any time, reducing the instrument size and installation and maintenance troubles.

1. There are no moving parts and flow-blocking parts in the pipeline, and there is almost no additional pressure loss during measurement.

2. The measurement results have nothing to do with physical parameters such as flow velocity distribution, fluid pressure, temperature, density, and viscosity.

3. The range can be modified online according to the actual needs of the user on site.

An electromagnetic flowmeter that uses the principle of electromagnetic induction to measure the flow rate of medium fluid. It adds a magnetic field on both sides of the pipe. When the measured medium flows through the pipe, it cuts the magnetic field lines and generates an induced electric potential on the two detection electrodes. Its magnitude is proportional to the movement speed of the fluid. It can be used to measure the flow rate of various suspended matter, gasified vapor and viscous substances such as acid, alkali, salt solution, coal water slurry, mineral slurry, mortar, pulp, resin, rubber latex, synthetic fiber pulp and photosensitive latex. The electromagnetic flowmeter has good sealing performance and can also be used in tap water and underground sewer systems. Moreover, the measurement process does not come into contact with fluids, making it suitable for pharmaceutical, biochemical and food industries. This flow meter also detects blood flow. Its range ratio is about 100:1, and its accuracy is generally 1%. Since this sensor must maintain a certain proportional relationship between the resistance within the pipeline and the impedance of the measurement circuit, it is difficult to manufacture. Difficulties begin to arise when the conductivity of the measured medium is about 10 ohm·cm, and fundamental difficulties arise when the conductivity is lower. When the conductivity is 10 ohm·cm, the "demarcation line" between conductive media and dielectric media is reached, and the thermal noise level increases significantly with the increase in internal resistance.
