 Verabar flowmeters always have a good advantage in plug-in flowmeters due to their unique advantages. The Verabar flowmeter is basically suitable for the measurement of all pipeline specifications on the site. The application on large-diameter pipelines shows more advantages. It is applicable to the flow measurement of various liquids, gases, and steam, especially ultra-low temperature, high temperature, high pressure, and humid fluids. The measurement of the medium. However, at the same time of application promotion, customers will also encounter the same problem of how to maintain. The following is a summary of the work and simple maintenance of Veripar flowmeter before it is put into operation:
1. Check the installation of the flow meter: After completing the installation of the Power Bar flowmeter, it must be inspected carefully. The welding is required to be firm, the direction is correct, and the test pressure does not leak.
2. Instrument calibration: read the manual of intelligent flow integrator carefully. According to the calculations attached to the Verabar flowmeter, the parameters in the intelligent flow totalizer are set correctly to ensure that the totalizer can correctly calculate and display the flow. If you go directly to the computer, you need to set the input data format and the corresponding compensation method inside the computer.
3. The instrument wiring is correct: The power flow meter and the flow totalizer together form a measurement system. Please check it repeatedly and make sure it is correct before putting it into operation.
4. System warm-up: After the commissioning preparation is completed, the measured medium is filled with the process pipeline, and the power flow meter is temporarily closed. At this time, the balance valve of the three-valve bank should be opened, and the high pressure valve and the low pressure valve are closed. status. Turn on the instrument and warm it up for 15 minutes.
5. System operation: After the preheating is completed, open the high pressure valve and low pressure valve of the three valve group, fill the differential pressure transmitter with the measured medium, open the drain valve after the differential pressure transmitter, and quickly discharge the dirty liquid or gas. Close the blowdown valve, 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, showing the media flow in the pipeline.
I believe everyone is not unfamiliar with Ebike Motors. According to the different position characteristics they are used on bicycles, there are no more than three common types. One is the Central EbikeMotor commonly used on mountain assisted bicycles. Given the characteristics of mountain Electric Bikes, riders need to quickly receive the assistance of an electric motor during their uphill and downhill journey in a very short amount of time. The central electric motor precisely fits this characteristic. As long as the foot is stepped on it, the motor will enter a working state, providing necessary strength support for riders, making outdoor mountain cycling particularly enjoyable and free. Another type is the rear wheel hub motor and the front wheel hub motor, which are commonly used on urban series power assisted bicycles. Because the most common time for people to ride in the city is during commuting to and from work, commuting to and from school, and ending a tiring day of work. Riding a favorite power assisted E Bike not only saves effort but also avoids the troubles caused by road traffic congestion. Lithium battery assisted bicycle operation with rear wheel hub Motor.
