Abstract: The information on how to properly maintain the Verabar flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. The Verabar Flowmeter is a plug-in flow measurement instrument. A Verabar
sensor is inserted into the pipe, and when the fluid flows through the sensor, a high-pressure distribution area is generated in the upstream direction in front of it, and a low-pressure distribution area is generated in the rear. sensor. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on how to properly maintain the Verabar flowmeter. The Verabar flowmeter is a plug-in flow measurement instrument. A Verabar sensor is inserted into the pipe, and when the fluid flows through the sensor, a high-pressure distribution area is generated in the upstream direction in front of it, and a low-pressure distribution area is generated in the rear. In the high and low pressure areas, the sensor has multiple pairs arranged according to certain rules, generally three pairs of pressure taking holes, which measure the total pressure of the fluid, including the static pressure, the average velocity pressure P1, and the static pressure P2. Introduce P1 and P2 into the differential pressure transmitter respectively, and measure the differential pressure △P=P1-P2, △P reflects the average velocity of the fluid, so that the flow rate of the fluid can be calculated. 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, and the pressure does not exceed 1.6Mpa. There are few opportunities for process pipelines to stop production, and there is basically no opportunity for pipelines to be stopped and empty. 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. Verabar flowmeter is basically suitable for the measurement of all pipe specifications on site, and its application in large-diameter pipes shows its advantages. It is suitable for flow measurement of various liquids, gases, and steam, especially for ultra-low temperature, high temperature, high pressure, and wet fluids. Measurement of media. Verabar flowmeter, differential pressure transmitter and flow totalizer together constitute a measurement system. Please check repeatedly and make sure that it is correct before putting it into operation; In the closed state, the balance valve of the three-valve group should be open, and the high pressure valve and the low pressure valve should be closed. Turn on the power of the instrument and preheat for 15 minutes; after the heating is completed, open the high pressure valve and low pressure valve of the three-valve group, charge the measured medium into the differential pressure transmitter, open the drain valve behind the differential pressure transmitter, and quickly discharge the dirty liquid Or close the blowdown valve after the gas, and then close the balance valve of the three-valve group, the transmitter will enter the measurement state, and the flow totalizer will also enter the working state to display the medium flow in the pipeline. ; After the installation of the Verabar flowmeter is completed, it must be carefully inspected, and the welding is required to be firm, the direction is correct, and there is no leakage in the pressure test; carefully read the manual of the intelligent flow totalizer. According to the calculation book attached to the Verabar flowmeter, set the parameters of the intelligent flow totalizer correctly to ensure that the totalizer can calculate and display the flow rate correctly. If you directly connect to the computer, you need to set the input data format and the corresponding compensation method inside the computer. The calculated differential pressure of the Verabar flowmeter is small, and generally do not discharge sewage. If the sewage is discharged for a long time, it will break the balance state of the high-pressure pressure-taking hole of the probe, which will lead to the situation of more and more blockage, and also make the low-pressure pressure-taking hole. Blockage is manifested in the low flow indication 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 during instrument maintenance work. For particularly important measuring instruments, the Verabar probe can be cleaned regularly, such as once / Month, it is required to check the appearance of the probe and the dredging of the positive and negative pressure taking 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. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. How to Properly Maintain Verabar Flow Meters
