The intelligent electromagnetic flowmeter developed by Changzhou Liangbang Instrument Design and Development is developed based on a standardized manufacturing system. Its advanced design concept ensures the high precision and high reliability of the product. Compared with the old-style electromagnetic flowmeter, it has the measurement High precision, reliability, good stability, complete functions, long service life and other advantages. The structure of the electromagnetic flowmeter is mainly composed of magnetic circuit systems, measuring conduits, electrodes, housings, linings, and converters. Below we will introduce in detail the specific functions and technical parameters of these components.

1. Shell: Made of ferromagnetic material, it is a cover for distributing excitation coils and isolates interference from external magnetic fields.
2, measuring catheter: Its role is to allow the measured conductive liquid through. In order to make the magnetic flux be diverted or short-circuited when the magnetic flux passes through the measuring catheter , the measuring catheter must be made of non-magnetic, low conductivity, low thermal conductivity, and a certain mechanical strength material. Non-magnetic stainless steel, fiberglass , and high strength can be used . Plastic, aluminum and so on.
3, magnetic circuit system: Its role is to produce a uniform DC or AC magnetic field. The DC magnetic circuit is realized by a permanent magnet. The advantage is that the structure is relatively simple and less disturbed by the AC magnetic field, but it is easy to polarize the electrolyte liquid in the measurement conduit so that the positive electrode is surrounded by negative ions and the negative electrode is positive ions. Enveloping, that is, the polarization phenomenon of the electrode, and the internal resistance of the two electrodes will increase, which will seriously affect the normal operation of the instrument. When the pipe diameter is larger, the permanent magnet is correspondingly large, heavy and uneconomical, so the electromagnetic flowmeter generally uses an alternating magnetic field, and is generated by 50HZ power frequency power supply excitation.
4. Electrodes: The effect is to elicit an induced potential signal that is proportional to the measured electrical potential. Electrodes are generally made of non-magnetic stainless steel and are required to be flush with the lining so that the fluid passes unimpeded. Its installation position should be in the vertical direction of the pipeline to prevent deposits from accumulating on it and affect the measurement accuracy.
5. Converter: The induced potential signal generated by the liquid flow is very weak, and is greatly affected by various interference factors. The role of the converter is to amplify and convert the induced potential signal into a unified standard signal and suppress the main interference signal. Its task is to amplify the induced potential signal Ex detected by the electrode into a uniform standard DC signal.
6. Lining: There is a complete electrical insulation lining on the inner side of the measuring conduit and the flange sealing surface. It is in direct contact with the liquid to be measured. Its role is to increase the corrosion resistance of the measuring tube and prevent the induced potential from being short-circuited by the metal measuring tube wall. Lining materials are mostly corrosion-resistant, high-temperature resistant, wear-resistant polytetrafluoroethylene plastics, ceramics, etc.
Electromagnetic flowmeter manufactured by Changzhou Liangbang Instrumentation . We are the domestic brand of high-end flowmeters . We can provide customized services to meet customer needs first, quality first and customers can rest assured. Changzhou Liangbang electromagnetic flowmeter's reputation in the industry and customer feedback are all satisfactory: high precision, durability, long service life, low failure rate, and good after-sales service. These are the customers' evaluations of us. The customers' recognition of Changzhou Chengfeng is the driving force for our progress. We are striving to develop new technologies, improve product performance, adopt high-quality materials, and meticulously adhere to the quality of our products, ensuring the passing rate of production testing is 100%.

Liangbang Instrument, only boutique, customer satisfaction is our driving force.

The electromagnetic flowmeters we research and develop have exquisite materials, superior quality and exquisite technology. The sampling rate of continuous sampling inspection is 100%. The service life of each high-precision electromagnetic flowmeter is 5-8 years, and the failure rate is extremely low. After a long period of use, maintenance can still be done after fault repairs. Maybe you will feel that this is a matter of righteousness and righteousness. Indeed, the people of Dacron are so understanding. Therefore, we strive to achieve the same quality as imported. These are all unmatched by some low-priced products in the current market. After an impetuous production and put into the market, they will be damaged for 1-2 years and cannot be repaired. From the perspective of environmental protection, it is undoubtedly a large amount of industrial waste. In terms of after-sales service, Changzhou Liangbang Instrument provides 24-hour gold medal service in the most user-friendly mode. It truly allows customers to buy with confidence. Changzhou Liangbang made the real domestic high-end electromagnetic flowmeter

  According to the temperature change of the working environment, the thermostat will have some physical deformations within the switch, resulting in some special effect. The thermostat will cause a series of automatic control element of turning off and turning on, which is also called temperature control switch, temperature controller, temperature protector, referred to the thermostat. Through thermal protector, the temperature protector will send the temperature to the thermostat and the thermostat will send the commands to control the operation of the device in order to achieve the desired temperature and the energy saving effect. Now the thermostat are widely used in thermostat application appliances, motors, cooling, heating and many other products.

  The working principle of the thermostat is automatically sampling, real-time monitoring through the temperature sensor. The control circuit starts when the ambient temperature is higher than the control set point. If the temperature still rise, when the temperature rose to over-limit alarm set point, the thermostat start limit alarm function. When temperature control can not be effectively controlled in order to prevent destruction of the device also can be stopped by the trip device features continue to run.

  According to the function of the working,the thermostat have different types:Intelligent Thermostat,Remote Controlled Thermostat,Programmable Thermostat,Wireless Room Thermostat.
