Split type sewage flowmeter

Split type sewage flowmeterIntroduction:

CS-LDE-1804Split type sewage flowmeterThe series electromagnetic flowmeter is an induction type instrument that measures the volumetric flow rate of the conductive medium inside the instrument based on Faraday's law of electromagnetic induction. It adopts embedded technology of single-chip microcomputer to achieve digital excitation, and uses CAN on-site president on the electromagnetic flowmeter. While meeting on-site display requirements, it can also output 4-20mA current signals for recording, regulation, and control purposes. It has been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, medicine, papermaking, and water supply and drainage. In addition to measuring the flow rate of general conductive liquids, it can also measure the volumetric flow rate of liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids.

Split type sewage flowmeterworking principle:

The working principle is based on Faraday's law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faraday's test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage is generated. The induced voltage generated by measuring the two electrodes inside the pipeline. The measuring pipeline achieves electromagnetic isolation from the fluid and measuring electrode through non-conductive lining (rubber, Teflon, etc.), as shown in the figure.

Split type sewage flowmeterAdvantages and unique selling points:

1. Optimize the design of the components required for the sensor - coils, and ensure the measurement accuracy of the product through rigorous real current testing

2. The signal electrode undergoes thorough electrostatic shielding treatment to ensure that small signals are not interfered by the coil and to guarantee measurement accuracy at low flow rates

3. The coil is isolated from the outside world to ensure its long-term insulation strength, which in turn guarantees the long-term measurement accuracy of the sensor

4. All welding processes of the sensor are carried out using argon arc welding technology. Although the cost is high, it can ensure the reliability of welding (welding is the main production process of the sensor), especially the welding process after installing the coil. Using argon arc welding technology can ensure that the installed coil is not damaged

5. Adopting a grounding electrode structure to form a balanced electrode plane ensures that the entire process of measuring the average speed is limited to the balanced electrode plane, which can effectively eliminate electrical noise interference and provide accurate measurement results
