Vortex flow meter scale how reasonable installation?

Abstract: the scale vortex flowmeter how reasonable installation? Information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Flow measurement instrument installed correctly is an important part of the protection of the normal operation of instrument, improper installation, light affect the use of the instrument accuracy, or will affect the service life of the instrument, even damage the instrument. Vortex flowmeter is essential in industrial production. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a vortex flow meter scale how reasonable installation? The article details. Flow measurement instrument installed correctly is an important part of the protection of the normal operation of instrument, improper installation, light affect the use of the instrument accuracy, or will affect the service life of the instrument, even damage the instrument. Vortex flowmeter is indispensable in the production of industrial measuring instrument of flow meter, can be measured gases such as superheated steam, nitrogen and other gases, measuring liquid such as water, methanol and so on. Let's talk about how to correctly install gas vortex street flowmeter, ( A) As far as possible to avoid the high voltage equipment, high-frequency equipment, switching power supply equipment. Instrument of power supply from these devices as much as possible. To avoid the high temperature heat source and the radiation source. If you have to install, you must have heat ventilation measures. Avoid high humidity and strong corrosive gas environment. If you have to install, you must have ventilation measures. Vortex flow meter should be avoid as far as possible to install on the strong vibration of pipeline. If you have to install, you must set up at the upstream and downstream 2 d pipeline fastening device, and vibration-proof pad, strengthen the effects of vibration resistance. Installed instrumentation zui good indoors, outdoors should pay attention to waterproof, pay special attention to in the electrical outlet cables should be bent into a U shape, avoid water along the cable into the amplifier shell. Instrument installation point should have a plenty of space around, in order to install the wiring and regular maintenance. （ 2) Vortex flow meter has certain requirement for straight pipe upstream and downstream of the installation points, otherwise it will affect the medium flow field in the pipeline, affect the accuracy of measurement instrument. Instrument of upstream and downstream straight pipe length requirements as shown in figure ( 3) Figure ( 3) Note: the regulator as far as possible not to install in the upstream of vortex flow meter, and should be installed downstream of the vortex flow meter 10 d. Upstream and downstream piping diameter should be the same. If there is any difference, the pipe inner diameter Dp and vortex meter Db table body size, should satisfy the following relationship between 0. 98分贝≤ Dp≤ 1. 5 db, the downstream piping should be with concentric flow meter table body size, not alignment between them should be less than 0. Between the instrument and the flange gasket, not protruding into the tube when installation, the inner diameter should be 1 - larger than the table body size Pressure hole and the installation of the thermometer hole design. Pipe to be tested when need to install the temperature and pressure transmitter, pressure hole should be set in the downstream of the 3 - 5 d, thermometer hole should be set in the downstream - 6 8 d, as shown in figure ( 7) 。 Instrument in on the pipeline can be horizontal, vertical or inclined installation. When measuring gas, in vertical piping instrument, gas flow to unlimited. But if the pipe contains a small amount of liquid, in order to prevent liquid from entering the meter tube, airflow should flow from bottom to top, as shown in figure ( 4) Measurement of liquid, in order to guarantee the tube filled with liquid, so in either a vertical or inclined pipe installation instrument, should guarantee the direction of liquid flow from the bottom up. If the pipe contains a small amount of gas, in order to prevent gas from entering the instrument measuring tube, the lower part of the instrument shall be installed in the pipeline. As shown in figure ( 4) As shown in figure (b 4) When measuring high temperature and low temperature medium, heat preservation measures should be paid attention to. Converter internal ( Header inside the shell) High temperature generally should not exceed 70 ℃; Easy to appear converter internal condensation at low temperature, reduce the insulation resistance of printed circuit board, affect the normal work of the instrument. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
