V cone flowmeter in scale advantage on water metering

Abstract: V cone flowmeter in scale in the water in the measurement of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1 groundwater resource metering installation environment and the requirements of table in the field of electrical shaft play more and more deep, because of drought and a large number of extraction of groundwater for irrigation, the underground aquifers deeper and deeper, means that the groundwater resource is more and more scarce. Irrigation water rising tensions. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a V cone flowmeter in the article details the advantages of scale on water metering. 1 groundwater resource metering installation environment and the requirements of table in the field of electrical shaft play more and more deep, because of drought and a large number of extraction of groundwater for irrigation, the underground aquifers deeper and deeper, means that the groundwater resource is more and more scarce. Irrigation water rising tensions, groundwater resources measurement issues should be referred to the agenda. Install metering with table can rational allocation and effective use of limited water resources, improve the efficiency of irrigation, eliminate unnecessary waste. Over the distribution of water, carries on the reasonable fee would be more effective to restrict and eliminate waste increasingly scarce water resources. General electric shaft in the wild, there are very few in the village. Because of cost of construction, the construction of the mouth of the well pump room, the space is very narrow, pipe fittings such as elbow, tee and valve is relatively concentrated, compact flow meter installed distance requirements, general straight pipe stretch. Additional centrifugal pump pump inlet pressure and pulsation of the larger, power grid voltage fluctuation and motor electromagnetic strength will have a certain influence on flow meter. And due to the direct extraction of groundwater, the water would float very fine sand, the wear and tear to flow meter; At the same time there will be gas, liquid and solid miscible flow, flow meter is not affected by the larger. Because it is a trade settlement with table, generally requires high accuracy ( See table 1) 。 Table 1 energy-using units energy metering accuracy grade of groundwater resources in flow of measurement instrument, instrument although has the pipe fittings such as elbow, tee and valve upstream is concentrated phenomenon, but the flow meter installed straight section of rectifying requirement for short as far as possible; Selected for pump inlet pressure is larger, the flow meter must have certain compressive strength; Pump inlet fluid pulsation is larger and the power grid voltage fluctuation and motor electromagnetic intensity, so the selection of flow meter to have certain resistance pump pulse and the voltage fluctuation and the intensity of electromagnetic ability; Due to the water floating sand, the wear and tear on the flow meter, so the selection of flow meter to have certain ability to resist wear and tear, zui good no moving parts and the sharp parts, the accuracy of sustained, and accuracy degree must also meet the requirements of table 1. Characteristics measurement in table 2 for groundwater resources more commonly used water metering meter include water meter, turbine, orifice plate, vortex street, ultrasonic, electromagnetic flowmeter and V cone flowmeter. The related characteristics of flow meter is shown in table 2. Table 2 several can be used in the measurement of groundwater resources in table comparing environmental requirements can be seen from table 2, due to the working principle of vortex street flowmeter, installed in the pump pulse is bad. Turbine, orifice plate, vortex street, ultrasonic, electromagnetic flowmeter requirements long straight pipe, general upstream ask 10 ~ 20 d, d downstream demand 5 ~ 10 d d. Turbine flowmeter has a high-speed rotating impeller, shaft and bearing is easy to water floating sand abrasion, ultrasonic and electromagnetic flowmeter cost is more expensive. Orifice meter orifice inlet edge sharp wear more easily, and the pressure loss is bigger. Water meter straight pipe don't need, but have a rotating impeller, non-metallic shaft and bearing is more likely to be the water floating sand abrasion. V cone flowmeter in short straight pipe requirements, general upstream request 0 d ~ 3 d, the downstream demand 0 ~ 1 d d, pulsating, volatility and electromagnetic is better, no rotating parts, good resistance to wear, so can prolong the service life and check cycle. From the aspects of table 2 of 5, 6 installation, 1, 2, 3, ripple, wave, and electromagnetic, and 4, 8 items of abrasion resistance, pressure loss and item 7 and 9 can extend the verification period. In the V cone flowmeter measurement has many advantages of groundwater resources. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
