When not to choose a turbine flow meter?

Abstract: When is a turbine flow meter not selected? The information is provided to you by the excellent manufacturers of flowmeters and flowmeters. Turbine flowmeter has the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, convenient installation and maintenance, etc. It is the main type of the new generation of velocity flowmeters. When the measured fluid flows through the turbine flowmeter sensor, it is flowing. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. Under what circumstances do not choose turbine flowmeters? Article details. Turbine flowmeter has the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, convenient installation and maintenance, etc. It is the main type of the new generation of velocity flowmeters. When the measured fluid flows through the turbine flowmeter sensor, under the action of the fluid, the impeller is forced to rotate, and its rotational speed is proportional to the average flow velocity of the pipeline. According to the principle of electromagnetic induction, a pulsating potential signal, that is, an electric pulse signal, will be induced in the coil. The frequency of this electric pulsation signal is proportional to the flow rate of the fluid being measured. The turbine flow sensor is matched with the display instrument. The sensor has the characteristics of high precision, good repeatability, long life and simple operation. It can be widely used in petroleum, chemical, metallurgy, papermaking and other industries to measure the instantaneous volume flow and total volume of liquids. Turbine flowmeters also have some situations that cannot be applied on site: fluids with many impurities: such as circulating cooling water, river water, sewage, fuel oil, etc.; places with rapid flow changes, such as boiler water supply systems, air supply systems with air hammers, etc. ; When measuring liquid, the pipeline pressure is not high and the flow rate is large, the pressure on the downstream side of the instrument may be close to the saturated vapor pressure, and there is a danger of cavitation. If liquid ammonia can flow freely from the high-level tank, it is not suitable for the discharge Installation; places where there is serious electromagnetic field interference near electric welding machines, motors, relays with contacts, etc.; the length of the upstream and downstream straight pipe sections is seriously insufficient, such as in the engine room of ships; boiler automatic water supply system such as frequent pump start and stop , which will impact the impeller and cause the turbine flowmeter sensor to be damaged quickly; care should be taken when selecting corrosive or abrasive media. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'When not to choose a turbine flow meter? 》
