Gas turbine meter scale selection

Abstract: how gas turbine meter scale selection information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Shanghai entreated, instrument and meter the flow of gas turbine flowmeter is a kind of common measuring instruments, with stable performance, flexible use, high reliability and convenient maintenance, etc. Users in the choose and buy gas turbine flow timing need to be aware of more problems, more detailed introduction. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how gas turbine meter scale selection article details. Shanghai entreated, instrument and meter the flow of gas turbine flowmeter is a kind of common measuring instruments, with stable performance, flexible use, high reliability and convenient maintenance, etc. Users in the choose and buy gas turbine flow timing need to be aware of more problems, more detailed introduction of gas turbine flowmeter selection method, hope you can help to you. *, precision grade. Turbine flow sensor precision grade are generally higher, usually the higher precision of the use of the environment is more sensitive. Economic benefits from the above, don't blindly pursue the high level of accuracy. For the big occasion of surface runoff, such as in the west to east gas pipeline project, be about to choose high precision sensors, while for the places of small throughput and measurement can choose ordinary turbine flow sensor. Second, the density of the gas. The stability of the gas density have much influence on accuracy of turbine flow sensor measurement, for frequent changes in density, also need to take correct way of processing on the discharge coefficient, especially for low flow area. Third, flow range. The choice of turbine flow sensor flow range directly affects its accuracy and use fixed number of year, it also determines the flow sensor size selection. Choose flow range is generally in accordance with the following principles: zui small flow rate should be greater than or equal to the zui small flow meter can measure, zui large flow rate should be less than or equal to zui large flow meter can measure; For uninterrupted work less than eight hours, the zui large flow rate shall be the actual zui large flow rate of 1. About three times; To work more than eight hours of uninterrupted occasions, the zui large flow rate shall be the actual zui large flow rate of 1. More than four times; Zui small flow rate shall be the actual zui small flow rate of 0. Eight times is preferred. Fourth, the pressure loss. The smaller the pressure loss, energy consumption in the process of gas flow in the smaller, so that we can save energy and reduce the transportation cost, improve the utilization rate. So when the choice, try to choose small pressure loss of turbine flow sensor. Generally, the use of half ellipsoid devices for a turbine flow sensor of than pyramidal diverter before turbine flow sensor smaller pressure loss. Fifth, the structure form. Structure identified by the above three methods: internal structure zui good choose the push type turbine flow sensor, because the structure within a certain range of traffic in a floating state, can make the impeller axis there is no contact point, endless surface friction and wear, can prolong the service life of bearing; For horizontal flow sensor installation structure, it and pipeline connection mode can be flange connection, threaded connection and clamp connection; For vertical structure installation flow sensor can only adopt thread connection. Correct selection of gas turbine flow sensor is not only related to the gas metering accuracy, can prolong the service life of the sensor, saving the maintenance cost. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
