Installation Elements of Verabar Flow Meters

Abstract: The information on the installation elements of the Verabar flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. Advantages of Verabar flowmeter 1. Stable signal Verabar's low-pressure pressure taking holes are located on the back two sides of the probe side, between the separation point of the fluid and the probe, away from the eddy current fluctuation area. 2. Excellent long-term high precision Verabar can ensure long-term stability of precision. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the installation elements of the Verabar flowmeter. 1. Advantages of Verabar flowmeter 1. Stable signal Verabar's low-pressure pressure taking holes are located on the back two sides of the probe side, between the separation point of the fluid and the probe, away from the eddy current fluctuation area. 2. Excellent long-term high precision Verabar can ensure long-term stability of accuracy because: (1) It is not affected by wear, dirt and oil. (2) There are no movable parts in the structure. (3) The design eliminates the occurrence of clogging. At the front of the probe, a high static pressure area surrounds the probe so that the high pressure tap hole will not be blocked. The most important thing is that the low-pressure holes are taken on the back two sides of the probe side, and the fluid swept across the surface obliquely, which protects the low-pressure holes from being swept, and other probes are easily blocked because their low-pressure pressure-taking holes are where impurities gather. Low pressure fluctuation area. 3. Low installation cost (1) Only a few inches of line welding is required, and the installation is very simple and fast. (2) Applying special tools can realize on-line installation under pressure. (3) All valves and interfaces of various instruments only need simple assembly, requiring very low assembly costs. 2. Inadequacy of Verabar flowmeter 4. The continuous working Verabar fundamentally eliminates the possibility of blockage, but in the following cases, Verabar should still pay attention to preventing blockage: (1) When the pressure pipe leaks, the high pressure of the probe is balanced. If the area is damaged, the smaller diameter particles in the impurities may enter the pressure hole. (2) When the pipeline is in shutdown, due to the Brownian motion of molecules, impurities with small particles may enter the pressure tapping hole. (3) The system is frequently turned on and off. At the moment when the high-pressure area is formed, impurities with small particles may enter the pressure-taking hole, and over time, it may cause the blockage of the probe. (4) The medium contains a lot of tar, algae, or fibrous substances, which may also cause blockage of the probe. 3. Application of Verabar flowmeter: Verabar flowmeter can be used to measure the flow of industrial water, filtered water, circulating water and other media in underground pipelines. Due to the large amount of impurities such as sediment, the temperature of the medium is not very high, generally at room temperature. The pressure does not exceed 1.6Mpa, and the production process pipeline has few opportunities to stop production, and there is basically no chance of pipeline shutdown and emptying. When we are selecting, the best solution is to use the online installation type Verabar, these probes are easy to pull out and clean at any time. Of course, if the user's dust removal effect is good, we also recommend the off-line installation type with the back blowing device, which can cope with most situations. However, if it is necessary to pull out for maintenance, it can only be carried out when the production is stopped, unless a valve or a threaded bolt is specially equipped to block the welding head. 4. Installation of Verabar flowmeter: Install it on a horizontal pipeline. When the medium is air and gas, Verabar should be installed at any position of the upper 160°, so as to ensure that the liquid in the gas will not enter the pressure guiding pipe and change The feeder must be installed at a position higher than the Verabar as much as possible, and the liquid discharge operation is performed when the meter is turned on. If it is liquid and steam, it can be placed at any position of 160° in the lower part. For liquid, any air bubbles can enter the pipeline. When conditions permit, it can only be installed in the upper part. The exhaust operation is performed when the meter 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 medium on both sides of the probe is similar, so that the pressure-taking hole is less likely to be blocked), for steam, the condensed water is allowed to enter the pressure-guiding pipe and flow into the condensing pipe. The device must be installed as low as possible from the Verabar. It can be installed on the vertical pipeline, and can be installed at any position of 360° around the vertical pipeline (to meet the straight pipe section), pay attention to correct the direction of the probe after installation, so that the fluid direction '→' on the probe and the fluid direction of the pipeline are kept at 3 5. Maintenance points of the Verabar flowmeter Because the calculated differential pressure of the Verabar flowmeter is small, generally do not discharge sewage. If the sewage is discharged for a long time, it will break the balance state of the high pressure tap hole of the probe, which will lead to excessive discharge. The more blocked the situation, the low-pressure pressure taking hole will be blocked, which means that the flow indicator is low after the meter is restarted. Therefore, it is usually emphasized that only system inspection and one-time zero-setting of the meter are carried out when the meter is maintained. For particularly important measuring instruments The Verabar probe can be cleaned regularly, such as once a month. It is required to check the appearance of the probe and the dredging of the positive and negative pressure holes during cleaning.At the same time, in order to ensure the accurate measurement of the small differential pressure, it is necessary to ensure that the static sealing points of the measurement system are not leaking when the installation is restored.
