Shanghai BeiFei Automation Instrument Co., Ltd is a modern economic entity which sets development, design, manufacture and sales together. We have a lot of professional technical personnel who had worked in electromagnetic flowmeters development of new technology, design, and application for many decades. At the same time, we have a lot of experiences in producing electromagnetic flowmeter and had been furnished with the most advanced water flow calibration device which is the most accurately in China now( for large caliber it use normative volume method, for small caliber it use exact weighting method ). The technics and the equipment are so advanced and we can provide any specialized uses electromagnetic flowmeters according to user’s requirements, for example, high pressure model, slurry model, loaded folder model, sanitation model electromagnetic flowmeters and so on. With reliable product qualities, reasonable prices, honest credit standing, perfect after-sale service, we will give our warmest welcome to all of you at home or abroad for inquiring and patronizing us.

Our products are widely applied to water supply and drainage, chemical industries, medical industries, metallurgy, textiles, paper making, vintage, electricity, sugar industries, pesticide and exterminals to overseas markets.

We have developed Teflon (PFA) lining material, using one-off molding technology, enhanced the combination of the lining and metal pipe, overcame the shortcoming of the thermal expansion coefficient of the lining and overcame the damage of the thermal expansion and negative pressure of the high temperature to the lining. We have patented the measuring pipe from the State Intellectual Property Office, which the catheter and the lining can be closely integrated with electromagnetic flowmeters. The patent number is ZL 200320108404.X.

We know that the large caliber electromagnetic flowmeters which is used for the serious polluted adhesive medium，for running long time, the surface of the electrode will be covered with a layer of non-conductive dirt, then it will be affected the output of the signal, in order to solve this problem, we have developed a new product which named scraper electromagnetic flowmeters, it can rid the dirt itself when the flowmeters have not taken down. At the same time, we have patented the technology of this product from the State Intellectual Property Office, too， and this product has gained Shanghai Hi-tech conversion projects. The patent number is ZL 200320108404.4.

Conductive rubber lining technologies is another new technology of our company, when the caliber of the rubber lining transducer is larger than 125, it can use conductive electrode in the lining, because it can ensure the grounding of the medium well and then saved the grounding ring, so it avoided the leak of using more electrodes grounded, assured the safety and economy of the flowmeters. The patent number is ZL 200620108602.4.

The water flow calibration device of our company has gained the certification of the Identification sector of China National Laboratory (CNAL), the uncertainty of it is better than 0.005% (K=2) and the high level stability devices containers of this system has patented from the State Intellectual Property Office. The patent number is ZL 200420082402.2.
