Small caliber (generally less than DN50) has fast response and small flow measurement scene; medium caliber (DN50-DN200) has wide measurement range and is used in urban water supply and other fields; large caliber (greater than DN200) is used for large flow measurement and is used in large pipelines.
It can be installed horizontally, vertically or obliquely to adapt to different pipeline layout and installation requirements.The installation process is relatively simple and does not require complex modifications to the piping.
Electromagnetic flowmeters can provide a variety of output signals, such as analog signals (4-20mA, 0-10 V, etc.), digital signals (RS485, HART, etc.), for easy connection and integration.

Electromagnetic flowmeters are based on Faraday's law of electromagnetic induction.When a conductive liquid flows in a magnetic field, it cuts the magnetic lines of force, thus generating an induced electromotive force in the liquid.The magnitude of this induced electromotive force is proportional to the flow rate of the liquid.
Electromagnetic flowmeter determines the flow rate of liquid by measuring the induced electromotive force, and then calculates the flow rate.
Specifically, the electromagnetic flowmeter is composed of a sensor and a transmitter.The sensor comprises an excitation coil for generating a magnetic field and an electrode for measuring the induced electromotive force.When the liquid flows through the sensor, the magnetic field generated by the excitation coil acts on the liquid, so that the charged particles in the liquid move in the magnetic field to generate induced electromotive force.The electrode detects this induced EMF and transmits it to the transmitter.

Electromagnetic flowmeters are essential in paper mills.It measures the flow of wood pulp and chemicals in the pulping process to ensure the quality and efficiency of pulping.In the papermaking process, the flow of pulp and additives is controlled to ensure the uniform and stable quality of paper.At the same time, in the white water circulation and sewage treatment, the flow can be accurately monitored and measured to help resource recycling and environmental protection standards.
Electromagnetic flowmeters play a key role in food plants.In the process of raw material transportation, it measures the flow of various liquid raw materials such as milk and fruit juice to ensure the accuracy of ingredients and the consistency of product quality.In the production process, it can monitor the flow of various process fluids on the production line in real time, help optimize the production process and improve production efficiency.
Electromagnetic flowmeter plays a significant role in textile mills.It measures the flow of dyes, auxiliaries and other liquids in the printing and dyeing process to ensure accurate dyeing formula and uniform and stable textile color.In the sewage treatment system of textile mills, the sewage flow is accurately monitored to provide the basis for the adjustment of the treatment process and help to meet the discharge standards.And is efficiently utilized in the process of recycling the production water.
