Abstract: the need to how to correctly choose and buy when buying a gas turbine meter scale items information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Gas turbine flowmeter flow sensor is advanced ultra low power single chip microcomputer technology of turbine flow sensor and display integrating the integration of the new intelligent instrumentation, adopts double row at the scene of the liquid crystal display, with compact bodies, intuitive and clear reading and. More flow meter manufacturers choose model price quote you are welcome to inquire, here is to how to correctly choose and buy when buying a gas turbine meter scale matters article details. Gas turbine flowmeter flow sensor is advanced ultra low power single chip microcomputer technology of turbine flow sensor and display the integration of integrating new intelligent instrument, adopts double row at the scene of the liquid crystal display, a compact bodies, intuitive and clear reading, high reliability, without external power supply interference, strong resistance to lightning strike, the whole machine function, low power consumption, superior performance, small pressure loss, the impeller has antiseptic function; There are standard signal simulation and digital pulse signal output, easy with the computer and digital systems, is a more advanced, the ideal flow meter. 1, the precision level: in general, selects the turbine flowmeter is mainly focuses on its high accuracy, but the higher the accuracy of flowmeter, more sensitive to the change of site conditions of use, therefore, the selection of precision instrument carefully, should from the economic point of view. Trade settlement instrument, for large diameter gas pipeline on the instrument investment is more economical, and on the occasion of medium accuracy with low throughput level. 2, flow range: same as above mentioned 3, the density of the gas, the gas turbine flowmeter, fluid property is mainly the influence of the gas density, its effect on the meter coefficient is larger, and mainly in the low flow area. If gas density change frequently, to meter the flow coefficient of correction measures. 4, the pressure loss: as far as possible choose small pressure loss of turbine flowmeter. Because the smaller the pressure loss of fluid through the turbine flowmeter, the fluid from input to output pipe the energy they consume less, that the total power will be reduced, thus can greatly save energy, reduce the transportation cost, improve the utilization rate. Someone did test, pressure loss of the influence of main component is a former director of turbine flowmeter, choose diverter before half ellipsoid compared with before choosing pyramidal flow diverter, the pressure loss of the turbine flowmeter can be greatly reduced. 5, structural type: ( 1) Internal structure appropriate chooses the type turbine flowmeter. Because the push structure within a certain range of traffic in a floating state, can make the impeller axial there is no contact point, endless surface friction and wear, can prolong the service life of bearing. ( 2) According to the pipeline connection mode selection, flowmeter has two ways of the horizontal and vertical installation, horizontal and pipeline connection flange connection, threaded connection and connection. Medium caliber choose flange connection; Small diameter and high pressure pipeline choose threaded connection; Clamp connection is only applicable to low small diameter; Vertical installation only threaded connections. ( 3) According to the environmental condition selection, considering the influence of temperature and humidity. Natural gas measurement to choose this type explosion-proof turbine flowmeter. 6, bearing, bearing of turbine flowmeter will typically have three classes of tungsten carbide, ptfe, carbon graphite material. Natural gas metering instrument bearing should choose tungsten carbide material. Above is a selection of main aspects to consider. Because of the turbine flowmeter type specification is various, especially the different factory product quality have difference, should try to collect the manufacturer and model selection of the products, the relevant technical standards such as data comparing repeatedly investigation before deciding. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
It is beyond doubt that benefits fork density meter manufacturer. Market sentiments are strong, especially in the light of growing v shape coriolis mass flow meter observed globally.
