The characteristics of wedge meter scale and installation considerations

Abstract: the characteristics of wedge meter scale and installation note information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Wedge flowmeter is in the eighty s began to gradually move toward practical a new type of flowmeter, the test piece is a v-shaped wedge ( Also known as the wedge throttling) , its sleek apex Angle down, this is helpful for containing suspended particles of liquid or viscous liquid pass smoothly. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a wedge meter scale features and installation considerations article details. Wedge flowmeter is in the eighty s began to gradually move toward practical a new type of flowmeter, the test piece is a v-shaped wedge ( Also known as the wedge throttling) , its sleek apex Angle down, this is helpful for containing suspended particles of liquid or viscous liquid pass, not stagnation in throttling upstream side. So is especially suitable for in petroleum, chemical and other industries for and volume flow to mass flow measurement. Wedge flowmeter features: 1) Suitable for measuring the mud, coal tar, coal water slurry and other high viscosity fluid; 2) Under the condition of low pipe Reynolds number ( Even as low as Re = 500) And stays a square root relationship between flow rate and differential pressure. The orifice meter measurement of small Reynolds number are much larger than the wedge flowmeter; 3) The separate calibration wedge flowmeter has higher measurement accuracy ( Up to 0. 5%) And without calibration of the wedge the accuracy of the meter can also be about 3%; 4) Simple structure, convenient installation, use and maintenance; 5) Measurable corrosive medium, due to the differential pressure measurement is the use of diaphragm type double flange differential pressure transmitter, corrosive media can't into the guide tube and the differential pressure transmitter, so as long as with corrosion resistant material processing wedge throttling, can make the gauges for measuring corrosive medium. Wedge flowmeter instructions: especially suitable for high viscosity, low Reynolds number, suspended particles or bubbles of medium measure; Measurement accuracy is not affected by fluid medium dielectric constant features of and restrictions; Wedge a special structural design, has guide effect, anti clogging; Changes with fluid viscosity, temperature, density and other compensation function; Vibration resistance, impact resistance, dirt resistance, anti-corrosion, explosion-proof; Simple structure, strong, high reliability, convenient installation and operation maintenance cost low, no moving parts, no wear, use for a long time do not need to calibration. Wedge flowmeter installation note 1, general wedge flow sensor attached before and after the measuring tube, available in horizontal or vertical installation and use. When the sensor installed on the vertical pipe, fluid should flow from top to bottom. The differential pressure transmitter should be paid attention to when measuring liquid can turn over to exclude bubbles, lest cause instrument drift; 2, sensors, straight pipe upstream and downstream side should configure, pipe inner surface should be smooth, clean, no attachments, just length as table; When mounted horizontally, 3, wedge type differential pressure components should be with the center line of the pipeline into 90 degrees. For vertical installations, because of the influence of take slightly between static pressure must pay attention to zero differential pressure transmitter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
