Differential pressure type classification of venturi meter scale

Abstract: differential pressure type venturi meter scale classification information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. One, the differential pressure type characteristics of differential pressure type of venturi meter venturi meter to a differential pressure type flowmeter, is compared to the traditional flow measurement instrument. Accuracy of the measurement of safe sex, also can meet the demand, in the reservoir and a few of the tap water company. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a differential pressure type classification of venturi meter scale article details. One, the differential pressure type characteristics of differential pressure type of venturi meter venturi meter to a differential pressure type flowmeter, is compared to the traditional flow measurement instrument. Accuracy of the measurement of safe sex, also can meet the demand, in the reservoir and a few have must use tap water company. Venturi meter by a venturi tube ( Save) And form a complete set of differential pressure transmitter, after measurement through the save pieces before and after the differential pressure to calculate the flow. This flowmeter save almost did not improve to the point, has been to improve the contrast, and has completed the standardization, the classification of the venturi meter: venturi meter according to the different equipment method is divided into pipeline venturi meter and Pierce the venturi meter, pipeline can be divided into the specification venturi meter venturi meter ( General pipe) Venturi meter and rectangle, rectangle venturi meter is working 'venturi tube, the first is about industrial enterprises large diameter and low flow velocity, large flow rate of gas flow measurement, a common construction planning, and in the national key points of large wind tunnel lab for real flow calibration. Can be widely used in petroleum, chemical industry, metallurgy, electric power and other major diameter control and measurement of the fluid. Into type venturi meter first used in diameter is too large, short straight pipe or equipment location restricted and demand for flow measurement accuracy is not high field is applied, it has convenient equipment debugging, without having to cut section, capital low wait for a characteristic, current is often used to replace the rectangle venturi and wing wind equipment, for the wind flow measurement. According to the machining method for different divided into rough cast to shorten the period of the specification of the venturi meter, mechanical processing and shorten the period of the venturi meter, with thick soldering iron plate to shorten the period of the venturi meter. Three, the primary characteristics of venturi meter: 1, construct a brief, durable, stable function, it is not easy to block. 2, small pressure loss, saving power needed for the traffic transportation, can be used in two phase flow, mixed phase flow and low flow velocity, large pipe diameter, special-shaped tube mixed and disorderly flow measurement. 3, high precision, good repeatability, small pressure loss, the straight pipe is shorter. 3, the size of 50 - 1200 scale, without demand flow calibration. Can exceed the size, reference planning production. When demand is high precision, real flow calibration can be performed. 4, equipment of ontology, the big size of large diameter appearance, is not convenient to transport equipment, can use thinking standard orifice, or into double venturi meter. Four, the venturi meter principle: the venturi meter is also called the classic venturi tube, the classical venturi tube, habit called venturi tube, standardize the venturi tube. Is developed according to the venturi effect after saving type flow sensor, is a kind of save equipment specification. In the 50 - Within 1200 mm size without real flow calibration, because of its high precision, small pressure loss, not easy to wear and tear, often as a transaction settlement class flow appearance for steam, gas, oil, the accurate measurement of chemical medium. The planning, production is according to GB/T2624-93 or ISO5167 planning, according to the national standard JJG640-94 test. Used in the measurement of pipeline of single-phase steady fluid flow, is often used to measure air, gas, gas, water and other fluid flow. In specification save equipment, its demand on the straight pipe, indecent zui short, persistent pressure loss zui, function stability, protection facilities. Because of its calculation precision, small energy consumption, has been widely used in petroleum, chemical, electric power, metallurgy profession. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
