Structurally, the electromagnetic flowmeter consists of an electromagnetic flow sensor and a converter. The sensor is mounted on an industrial process pipe. Its function is to linearly convert the liquid volume flow value flowing into the pipe into an induced potential signal and send this signal to the converter through the transmission line. The converter is placed not far from the sensor, it amplifies the flow signal sent by the sensor and converts it into a standard electrical signal output proportional to the flow signal for display, accumulation and regulation control.

 

The principle of electromagnetic flowmeter measurement is based on Faraday's law of electromagnetic induction. The measuring tube of the flow meter is a non-magnetic alloy short tube lined with an insulating material. The two electrodes are fixed to the measuring tube through the tube wall in the tube diameter direction. The electrode tip is substantially flush with the inner surface of the liner.

 

There are many manufacturers of electromagnetic flowmeters in China. After decades of technological imitation and independent innovation, the quality of domestic electromagnetic flowmeters has been greatly improved. Through more than five years of research and development, we have introduced a high-quality and more user-friendly "modular electromagnetic flowmeter".

 

HHLD intelligent electromagnetic flowmeter is the first all-intelligent flowmeter with modular design, window replacement, online replacement core components and fault self-diagnosis. It has eight core patent technologies, which are quite large compared with analog electromagnetic flowmeters produced by other manufacturers. The difference, especially in measurement accuracy reliability, stability. It is also possible to modify the flowmeter range, which has been greatly improved in terms of function and service life. The electromagnetic flowmeter is designed with a Chinese liquid crystal display with wide backlight and wide temperature. It is complete in function, intuitive in display and convenient to operate and use.

 

Features of HHLD modular electromagnetic flowmeter: 1. Integral and split type optional; 2. Fluid state is visible, whether the medium in the flowmeter is full of tubes, visible through the window; 3. Free length adjustment, greatly adapt to the scene, It can directly replace any manufacturer's products at home and abroad, without changing the length of the pipeline at the site; 4. Online pressure can be removed, easy to maintain, the flowmeter electrode and other components can be replaced online, the faulty products do not need to be returned to the factory, and the production is not delayed; 5. Modular design Input the parameters of the replacement parts, the flowmeter CPU automatically debugs to the factory state; 6. Highly intelligent, the flowmeter with fault self-diagnosis, convenient for the user to intuitively determine the location of the fault and the cause of the fault.
