Abstract: the application of mass flow meter scale for measuring the limestone slurry density is introduced information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: because of the desulfurization system of serous corrosion resistance and abrasion resistance, and has high solid content, Up to 30%) To the conventional test method of measuring the density and the density meter selection is very limited. This article mainly introduced the domestic serous desulfurization system. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the application of mass flow meter scale for measuring the limestone slurry density introduction for details. Because of the desulfurization system of serous corrosion resistance and abrasion resistance, and has high solid content, Up to 30%) To the conventional test method of measuring the density and the density meter selection is very limited. This article mainly introduced the domestic desulfurization system three measuring methods of slurry density. Differential pressure method, & gamma; Ray radiation absorption measurement, and the method of coriolis force mass flowmeter. For readers' reference. Because of the desulfurization system of serous corrosion resistance and abrasion resistance, and has high solid content, Up to 30%) To the conventional test method of measuring the density and the density meter selection is very limited. At present, the domestic desulfurization system there are three kinds of slurry density measurement method mainly, namely the differential method, & gamma; Ray radiation absorption measurement, and the method of coriolis force mass flowmeter. Coriolis force mass flowmeter measurement desulfurization system limestone slurry density is due to the structure of the flow meter and the structure of vibration tube densimeter affinity. Measuring tube continuously at a resonant frequency vibration, due to the resonance frequency is a function of fluid density, when different density of fluid filled pipe vibration, the vibration frequency of the vibration pipe will also change. Therefore measure the frequency of the vibration tube change completes the measurement of the density. This method, it is current mainstream slurry density measurement method. The way to measure precise and reliable, to adapt to the wide range of slurry density. Can satisfy completely the requirements of field use. To make better use of this product must pay attention to the following several aspects. 1: should be measured when installed vertical or horizontal pipe up, protect the measuring tube from the solid residue accumulation sounding pipe caused by the accumulation of frequency change, affecting the accuracy of the density measurement. 2: the factory when the density of coriolis force mass flowmeter is used to measure the flow velocity is ignored or flow the effects on the mass flowmeter. Through the mass flowmeter medium flow to a density meter measuring accuracy does not directly influence, but high-speed flow of limestone slurry wear for quality meter measuring tube is very big, so as to affect its service life. So try to make through the quality of traffic not too high in order to improve the service life of the lower costs. Specific measure is that if the main line traffic quality meter can be installed when the bypass, through the size of the valves control the flow. 3: don't directly installed in a vertical vent pipe exports, should be on the pressure side of the pump ( To prevent the low voltage) 。 4: after using for a long time due to material, wear and corrosion cause changes in the measuring tube mechanical structure, the resonance frequency has been affected by these factors resulting in density measurement precision reduce must adjust the site to check. 5: for a long time before the outage application water pipe to prevent limestone adhere to the wall even pipeline caused by the measurement accuracy of falling even unable to measure. The differential method for indirect measurement method, namely through the differential pressure transmitter measuring pressure difference between high serum, according to & rho; = P/gH to calculate the density of slurry, including & rho; As the slurry density, P for differential pressure transmitter to measure pressure, H for a fixed distance, g is constant. Its main advantage is cheap, don't need to separate measurement piping system. But measuring probe easily blocked, caused serious instrument data unchanged, losing monitoring function. The other measurement precision is low. Due to the density of the slurry is not in every point is uniform, resulting in the deviation. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
