I. The operational principle of water flow sensor—A brief introduction Water flow sensor is a kind of instruments used for testing flow parameters of media like liquid and gas and to change them into other forms of signals for output. Water flow sensor has advantages of small size、light weight、audio—visual and clear reading、high reliability and zero pressure loss. As a result, it has been widely used in many areas such as environmental monitoring、safety protection、health care and trade settlement. However, it can not measure the flow that is non—conductive medium, which limits its development in a sense. II. The operational principle of water flow sensor—Classification Water flow sensor can be divided as water flow sensor、plug—in water flow sensor 、vane—typed air-water flow sensor、vortex water flow sensor、Karmen—vortex air-water flow sensor and hot—wire air-water flow sensor, etc., among which water flow sensor is mainly composed of copper valve body、flow rotor assembly、s

1.The points of installation (1) The mount point should choose the lowest place in the pipe after ensuring the flow direction of the measured material. The mount point should be selected at any time when the pile is full of fluid in case of the error caused by the indicator which is not in the zero position due to the vacancy of fluid in the pipe. (2) The straight length should be kept in the front of 5D and in the rear of 3D In order to acquire the measuring accuracy of the instrument, the flow development length of the upstream side in the sensor is not less than 5D, and the downstream side is not less than 3D ( D is the nominal diameter of the sensor). If there are two or more angel heads or other baffles in the upstream side, the front straight length should be larger than 10D. (3) The signal electrode is in the horizontal direction To make the electrode axis parallels the horizon when installing horizontally for the electrode at the bottom will be covered by precipi

Description of Electromagnetic Flowmeter Electromagnetic Flow Meter Price List Electromagnetic flowmeter is a kind of inductional instrument designed by Faraday’s law of electromagnetic induction to measure flow of conductive media in the tube. It adopts the technology of insertion of single chip to realize digital excitation and employs CAN local fieldbus. Magnetic inductive flow meter can realize local indication and output electrical current signal of 4-20mA which can be used to record, adjust and control.  Mag meter   is industrial flow meter; it can be used in environmental protection, metallurgy, pharmaceutical, paper making, water supply (magnetic water meter) etc. Besides measuring flow of general conductive liquid, magnet meter can measure flow of liquid-solid mixed fluid, high-viscosity fluid and salt, strong acid and strong alkali to be used as chemical flow meter, sanitary flow meter or sewage flow meter. We are supplier for full bore  electromagnetic flow mete
