Water flow instrument selection points

Abstract: water flow instrument selection points of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Water diversion project, water plant, sewage treatment plant water flow at the inlet and outlet of the measurement is the key measure in water sector, is a production enterprise statistics, production cost and leakage of pipe network, and the energy consumption of the main production run indexes such as the important basis, is essential to water industry. More flow meter manufacturers choose model price quote you are welcome to inquire, here is water flow instrument selection points article details. Water diversion project, water plant, sewage treatment plant water flow at the inlet and outlet of the measurement is the key measure in water sector, is a production enterprise statistics, production cost and leakage of pipe network, and the energy consumption of the main production run indexes such as the important basis, is an essential part of the water industry measurement. In and out, the critical water flow measurement instrument selection and how to correctly choose flow meter and improve the level of measurement test is an important work. Water diversion project, water plant, sewage treatment plant of import and export flow measurement using the flow meter compared with other areas has its special requirements. First, the calibre of the flowmeter is bigger, the scope of the general DN300mm - DN1000mm domestic zui large diameter electromagnetic flowmeter which have been successfully used to achieve DN3000mm; Shanghai Kent intelligent instruments this year shenzhen water supply reach DN3200mm zui large diameter. Second, the water flow metering is large, generally for thousands to tens of thousands of m3 / h. In addition, in order to ensure that meet the requirements of supply and drainage trade measurement, the selection of flow meter requires high accuracy; And installation location limitations so because of the large flow meter diameter of straight pipe request not too high. According to the characteristics of water flow at the inlet and outlet when we choose our flow meter will pay attention to the following aspects: 1. The process pipe diameter high requirement of the flow meter of pressure loss as small as possible. Generally do not use pipe local reducing method for improvement of the flow velocity. 2. New design and installation of piping, generally choose proper flow rate. Because of the low velocity of the fluid flow meter diameter is large, the corresponding instrument investment increased. Fluid flow velocity is too high, can cause dynamic pressure loss is large, rising operating costs, are not economic, but selection for future expansion when you left traffic allowance; 3. Due to the low velocity of the fluid, the fluid in the dirt, can appear after a long time to run the mud and scale deposit on pipe wall and electrode extremely easily, etc. In engineering design should be considered when the part in contact with the fluid cleaning instrument; Such as not washing and choose electromagnetic flow timing scraper type electrode can be used; 4. Instrument of measuring range specifications. Some water during the day and night, winter and summer flow difference, as many as several times, as a result, the water meter, requires a particularly large scale range degrees; 5. Meter high protection grade requirements. Most of large diameter pipeline buried in order to save investment and space, in the north, also is the need of antifreeze. So most separation flow sensor is installed in the instrument well. Because of the rain, pipe wall leakage and leakage reason often causes of borehole water level rise and submerged flow sensor, so the design should be estimated to this kind of situation, choose submersible type of flow sensor, such as IP68 protection grade. At the same time instrument Wells to waterproof engineering treatment. 6. Due to the big flow meter calibration often difficult disassembly, transport and install, and are not allowed to block and production process, hope to online dry calibration instrument. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
