Online Installation Requirements for Verabar Flowmeters

First of all, I would like to tell you about the requirements for the upstream and downstream straight pipe sections when the Verabar flowmeter is installed. If it is installed too close to the bend, is the measurement result still credible? ! For the installation of the Verabar flowmeter, refer to the installation method of the average velocity tube or the compact orifice flowmeter, try to stay away from the corner, and follow the principles of the first 10 and the last 5. When measuring water vapor, the sampling port is in the lower half of the horizontal pipe, so that the pipe is filled with liquid (for example, at 45 degrees below the horizontal), and other installations are installed according to the gas and liquid. Installation according to the first 10D and then 5D can meet the installation requirements of the Verabar flowmeter. But D refers to pipe diameter. It is good to measure the liquid, but the flow rate depends on the side gas, high flow rate is also good, too low is not good, so everyone must pay attention. Secondly, let’s talk about how to realize the online installation of Verabar flowmeter? Let’s talk about it now, the application of Verabar flowmeter is still very wide, especially the probe of Verabar flowmeter, so more and more people will encounter such problems: how to install, how to use and even how to maintain Verabar bar flow meter? The first two questions have been answered before, so how can you ensure that your Verabar flowmeter works well for you? Of course, it depends on your measurement object. In order to ensure the accurate measurement of small differential pressure, the zero position requirements of differential pressure transmitter are also high. Therefore, we must pay attention to the zero work of primary instruments, such as for key measuring instruments. Perform a regular/weekly zero calibration. In addition, since the calculated differential pressure of the Verabar flowmeter is small, generally do not perform sewage discharge. If the sewage is discharged for a long time, it will break the balance of the probe's high-pressure pressure hole, which will lead to more and more clogging, and make the The low-pressure pressure-taking hole is blocked, and the flow indication is low after restarting the meter. Therefore, when performing instrument maintenance work, it is emphasized that only system inspection and instrument zeroing should be carried out once. For particularly important measuring instruments, the Verabar probe can be checked regularly Cleaning, such as once/monthly, 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, the static sealing points of the measurement system must be guaranteed when the Verabar flow is restored. Not leaking.
