Brief description of the application and installation of Verabar flowmeters

Weiliba flowmeter can be used to measure the flow of medium such as underground pipeline industry water, filtered water, circulating water, etc. Because of the large amount of impurities such as sediment, the medium temperature is not very high, generally at room temperature, the pressure does not exceed 1.6Mpa, and the production There are few opportunities for production pipelines to stop production, and there is basically no opportunity for pipelines to be deactivated.

When we select the type of Verabar flowmeter, the best solution is to use the online installation type of power bar. These probes can be easily removed at any time. Of course, if the user's dust removal effect is good, we also recommend using a non-inline mounting type equipped with a blowback device that can handle most situations. However, if it is to be pulled out for maintenance, it can only be done when the production is stopped, unless a valve or threaded bolt is fitted to block the welding head.

The horizontal pipeline is installed. When the medium is air and gas, the power bar should be installed at any position in the upper 160° so that the liquid in the gas will not enter the pressure guiding pipe. The transmitter must be installed as high as possible. The position of the bar, when the table is open, the discharge operation.

In the case of liquids and vapours, any air bubble can enter the pipeline at any point in the lower part of 160°, and when the conditions permit, it can only be installed in the upper part. Then the exhaust operation is performed when the table is opened (the underground pipeline is basically the same, In the case of silt in the underground pipeline, it is recommended that the probe should be installed vertically to ensure that the flow of the media on both sides of the probe is similar, so that the pressure hole is more difficult to block). For steam, condensate water is allowed to enter the pressure guiding pipe and flow into the condensing pipe. The device must be installed below the power bar. Installation on a vertical pipe can be installed anywhere around 360° on the vertical pipe (satisfying the straight pipe section). Pay attention to correct the direction of the probe after installation so that the direction of the fluid “→” on the probe and the direction of the pipe fluid remain at 3 ° within.

Due to the low differential pressure calculated by the Verabar flowmeter, it is generally not required to discharge the pollutants. If the pollutants are discharged for a long time, the balance of the probe high-pressure pressure-receiving holes will be broken, which will result in a situation in which the plugging will be blocked and the pressure will be reduced. The hole is blocked and the flow indication is low after reopening the table. Therefore, in the normal maintenance of the meter, it is emphasized that only the system check and the instrument zero are performed. For a particularly important meter, the power sensor can be cleaned periodically. One time/month, it is required to check the appearance of the probe and the clearing of the positive and negative pressure holes during cleaning. At the same time, in order to ensure accurate measurement of small differential pressure, it is necessary to ensure that the static sealing points of the measurement system do not leak when the installation is resumed.
