High Accuracy Turbine Vortex Liquid Control Intelligent Electromagnetic Flow Meter
An electromagnetic flowmeter is an instrument commonly used to measure liquid fluids. It uses Faraday's law of electromagnetic induction to determine the flow rate of a fluid by measuring the conductivity in the liquid and the velocity of the conductive liquid flowing through the pipe.
Magnetic flowmeters consist of two main parts: a sensor and a converter. The sensor is usually mounted on the pipe and interacts with conductive substances in the liquid via a magnetic field. When the liquid flows through the pipe, the sensor generates a magnetic field and then measures the induced electromotive force in the conductive liquid. A converter is a device connected to a sensor that processes and interprets the signal generated by the sensor. It converts the induced electromotive force into a readable digital signal, and provides flow display, output interface and other functions such as alarm and control.

Communication and service platform
1. What data can the platform collect from the water meter?
Currently, our platform can collect cumulative flow, battery voltage, and upload time on the water meter.
2. How do you know that the water meter is faulty and there is no data to return?
First, we can check the alarm function on the platform to see if the water meter has no data returned, and then check the
installation environment to see if there is any obvious damage, and can actively trigger the water meter to turn on-line mode .
3. Is the platform free? Can I pay in advance?
It is free, and the administrator can charge the amount in advance
Set user information files for each user on the platform
