Abstract: the explanation place for gas flow sensor installation position and key points of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. , a gas flow sensor installation location, location and main points, hope the following will help to your understanding of the gas flow sensor. One, the gas flow sensor installation place of gas flow sensor should be for - in the temperature of the gas being measured 20~+60℃。 More flow meter manufacturers choose model price quote you are welcome to inquire, here is a place for, a gas flow sensor installation location details and main points of the article. , a gas flow sensor installation location, location and main points, hope the following will help to your understanding of the gas flow sensor. One, the gas flow sensor installation place of gas flow sensor should be for - in the temperature of the gas being measured 20 ~ + 60 ℃, relative humidity environment under the condition of no greater than 95% of the work. Think in terms of maintenance convenience, should be installed in easy conversion and avoid piping vibration or the place of piping stress influence. Considering the protection of the amplifier, should avoid as far as possible to make it affected by the strong thermal radiation and radioactive. At the same time, must avoid the outside strong electromagnetic field to test the effects of coil, such as unavoidable, should be set up on the gas flow sensor amplifier shield, otherwise interference will seriously affect the work of display instrument often work. Second, the gas flow sensor installation position of the gas flow sensor should be installed, install the directions on the sensor when the flow arrow should be consistent with the direction of fluid flow. Three, the key points of piping gas flow sensor 1, in order to remove the gas vortex and uneven flow velocity influence on the measurement of area, should be in the import and export in sensor placement necessary straight segments or rectifier. General requirements upstream part ( Inlet) The straight pipe for ( 15 ~ 20) D( D for sensor nominal diameter) 。 The downstream section ( The exit of the straight pipe length is 2 ~ 5 d) And straight pipe diameter and sensor shall be the same size. 2, in order to remove the impurity in the fluid, ensure the normal work of the sensor, improve the service life of sensors, in front of the gas flow sensor pipe shall be fitted with mesh for 40 - on the road 80 mesh/cm 2 filters. Normally size large mesh loose, size small mesh density. In order to ensure the normal operation of the gas flow sensor, also should be selected according to the actual usage of filter mesh. 3, when the welding gas flow sensor inlet flange, must pay attention to the tube without highlights. When import flange connection, the two flange peripheral to perfectly match, the washer can not exposed to the tube. Eccentric reducing joint will cause uneven flow velocity distribution phenomenon, it cannot be used. 4, in order to guarantee the need of maintenance under the working size, gas flow sensor should be placed to cut off the valve in the pipeline before and after ( Globe valve) The by-pass pipe shall be set up, and at the same time. Flow control valve on the downstream side of the sensor is loaded. Sensors used in the upstream of the valve must be fully open load, avoiding the phenomenon of the upstream part of the produced fluid turbulence. 5, through the flow of gas flow sensor is too large, Exceeding the maximum limit flow range) , bearing for high speed and speed up the wear and tear. Therefore, in the case of is expected to have excessive flow, available in the downstream part of the flow control valve regulating fluid flow. 6, in the new pipeline installation gas flow sensor, in order to avoid impurities into the sensor in pipeline, should be with a empty tube instead of sensor after running for a period of time, confirm the impurities have excluded and changing the sensor. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
Nowadays, the adoption of mass flow meter in endress hauser coriolis mass flow meter industry is quite common.
We humbly ask you to use mass flow meter and we guarantee that you would be in a great delight with using the product.
On top of making sure all our day-to-day operations are running smoothly, Beijing Sincerity Automatic Equipment Co., Ltd needs to ensure that we're keeping up with all the quality standards of mass flow meter.
To offer abundant options of product is an important factor to a company, such as mass flow metercoriolis mass flow meter emerson to afford high-quality products for customers.
