1. What is the working principle of Kent flowmeter remote transmission equipment? The working principle of Kent flowmeter remote transmission equipment is to measure the flow rate of conductive liquid through electromagnetic induction, and then remotely transmit the data to the control center through communication technology. The principle of electromagnetic flow measurement is based on Faradays law of electromagnetic induction, which generates induced electromotive force when a conductive liquid flows through a magnetic field. • Generate magnetic field: After the excitation coil inside the flowmeter sensor is energized, a stable and steady magnetic field is generated inside the pipeline. Cutting magnetic induction lines: When a conductive medium flows through a magnetic field area, it will cut the magnetic induction lines. • Generate potential difference: An induced electromotive force is generated on an electrode perpendicular to the magnetic field and flow direction, and its magnitude is proportional to the average flow velocity of the fluid. • Signal conversion: After amplification and filtering of weak electrical signals, the processor calculates the instantaneous flow rate and cumulative flow rate.
2. The flow data measured by remote data transmission is sent to the remote monitoring system through wired or wireless means. Wired transmission: Usually using 4-20mA analog signals or industrial fieldbus protocols such as RS485/MODBUS, directly connected to PLC or DCS systems. Wireless transmission: Data can be uploaded to cloud platforms or monitoring centers through wireless networks such as 4G/5G, NB IoT, or Wangkuanzhuang LoRa, enabling unmanned remote monitoring.
2. Do electromagnetic flow meters
Hebei Hongyes electromagnetic flowmeter is widely used for measuring the volumetric flow rate of conductive liquids and slurries in pipelines in industries such as chemical, mining and metallurgy, water supply and drainage, papermaking, medical waste medicine, food, petrochemical, power, light industry, agricultural irrigation, and water conservancy. The working environment is simple and suitable for on-site display and direct reading. For complex working conditions such as toxic gas and highly corrosive liquid measurement environments, it is necessary to configure a pulse output accumulator or connect a current output to a computer. Implement remote control. The flow meter can display instantaneous flow rate, flow velocity, flow percentage, cumulative positive and negative flow rate, and differential flow rate for easy reading. There is a three-level password setting function inside to prevent data from being changed arbitrarily. The electromagnetic flowmeter of Hebei Hongye
