Abstract: how to prevent liquid turbine flow meter scale appear all sorts of electrical interference phenomenon of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Liquid turbine flowmeter is adopted advanced ultra low power single chip microcomputer technology of turbine flow sensor and display integrating the integration of the new intelligent instrumentation, has a compact bodies, intuitive and clear reading, high reliability, without external power supply interference, anti lightning strike. More flow meter manufacturers choose model price quote you are welcome to inquire, here's how to prevent liquid turbine flow meter scale appear all sorts of electrical interference phenomenon, the article details. Liquid turbine flowmeter is adopted advanced ultra low power single chip microcomputer technology of turbine flow sensor and display the new intelligent instrument of integration of integrating with compact bodies, intuitive and clear reading, high reliability, without external power supply interference, lightning resistance, low cost, obvious advantages. Liquid turbine flowmeter in the process of measurement, when the measured medium by flow meter, can make the impeller rotation, through the corresponding structure, the impeller blades of periodic rotation process, the instrument of the magnetic resistance is cyclical change, which made the flow of the liquid turbine flow meter and instrument is directly proportional to voltage pulse signal, so that the flow rate and the signal after under the action of low power amplifier into signals to the measurement system of MCU, it passes through a series of calculation and revised, on a meter display shows the instantaneous flow and cumulative flow effectively. Liquid turbine flow meter is the main species in the speed meter, when the current sensor through the liquid turbine flow meter, the body under the action of fluid, force rotating impeller, its speed is proportional to the mean velocity of pipe, at the same time, the blade cutting electromagnet field lines, periodically change coil magnetic flux, according to the principle of electromagnetic induction, within the coil will sense the voltage signal of the pulse, the electric pulse signal, the electrical pulse signal is directly proportional to the frequency and the flow of traffic. As the liquid turbine flow meter in the measurement of the flow of viscous medium and get more and more widely used, both at home and abroad to & other; Liquid viscous medium of turbine flowmeter measurement & throughout; Research is also more and more will embody its important value and practical significance. Series liquid turbine flowmeter can be used to measure low viscosity liquid flow, such as water, gas, etc. Liquid turbine flow meter manufacturers generally measured liquid viscosity also rules shall not be greater than 5 mpas, otherwise will result in serious error. How to use the traditional turbine flow sensor measurement of liquid viscosity greater than 5 right mpas liquid flow, such as crude oil, machine oil flow, will cause our attention widely. Liquid turbine flowmeter pictures how to prevent the turbine flowmeter appear all sorts of electrical interference phenomenon: 1, liquid turbine flowmeter have higher request for the purity of the fluid, the flow meter must be installed before the filter to ensure that the cleaning fluid. Filter funnel type can be used, its cleanliness, measurable its differential pressure at the ends of the change. 2, in order to guarantee through the turbine flowmeter is single-phase fluid, namely cannot let air or steam into the flowmeter, turbine flowmeter upstream when necessary should install gets over. For easy vaporization of liquid, the turbine flowmeter downstream must ensure that the back pressure. The size of the back pressure desirable zui pressure drop under heavy traffic flow sensor twice and zui measured liquid under the high temperature steam pressure of 1. 2 times. 3, the flow rate distribution and the existence of the secondary flow is the important factors that affect liquid turbine flowmeter measurement accuracy. So, the turbine flowmeter is - for straight pipe upstream or downstream On request. For industrial measurement, generally requires the upstream 20 d, 5 d downstream straight pipe length. Is to eliminate the secondary flow, zui to upstream end with rectifier. There are about 20 d if the upstream end can guarantee the straight section, and adding rectifier, can make the measurement accuracy of turbine flowmeter calibration accuracy of grades. Liquid turbine flowmeter is a kind of precise flow measuring instrument, matched with the corresponding flow integrating instrument can be used to measure the rate of flow of liquid and the total amount. Liquid turbine flowmeter is widely used in petroleum, chemical industry, metallurgy, scientific research in the areas of measurement and control system. Equipped with joint health liquid turbine flowmeter can be used in the pharmaceutical industry. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
