The unique performance of the orifice flow meter

Abstract: The unique performance information of the orifice flow meter is provided by the excellent flow meter and flow meter manufacturers. Orifice flowmeter is a new generation of flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate for temperature and pressure. Orifice flow meters are filled with fluid in the pipeline, and as they flow through the throttling device in the pipeline, the flow stream will be at the throttling device. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the unique performance of the orifice flowmeter. Orifice flowmeter is a new generation of flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate for temperature and pressure. The orifice flowmeter is filled with the fluid in the pipeline. When they flow through the throttling device in the pipeline, the flow beam will form a local contraction at the throttling part of the throttling device, so that the flow rate increases and the static pressure is low. There is a pressure drop before and after, that is, the pressure difference. The greater the flow rate of the medium flow, the greater the pressure difference generated before and after the throttling element, so the orifice flowmeter can measure the fluid flow by measuring the pressure difference. For users who are just starting to use, we should pay more attention to the selection. If you choose a seller, you can go to Nanjing Jinnuo Instrument to have a look. It is also important to compare multiple flow meters. Nanjing Jinnuo Instrument is a manufacturer specializing in the production of throttling devices. Whether it is product procurement or technical consultation, it is an enterprise you can trust. The orifice flowmeter consists of three parts: sensing, transmission, and operation display. It is mainly suitable for industrial measurement of saturated steam, superheated steam, compressed air, mixed non-flammable and explosive gases and hot water. Flow measurement and display of the above fluids , measurement and online automatic control of the production process can be used. The most important thing to pay attention to when putting into operation is that the pressure guiding pipe must be filled with water or injected with high temperature steam to cool before starting operation. 1. The pressure guiding pipe system is filled with cold water as the pressure guiding medium, and the measurement of high temperature steam is generally conducted through the cold water. When the pipeline is not transporting steam, open the primary valve, pressure valve and balance valve, close the drain valve, and directly inject cold water from the water injection hole of the condensate tank until it is fully filled. Of course, the balance valve and pressure valve can also be closed, and the valve can be opened once to introduce high-temperature steam and slowly cool it into water. This method is generally not used because the steam temperature is too high and it is easy to damage the instrument. Special attention should be paid to the measurement of high temperature steam when the pressure guiding pipe is not filled with water or the temperature is very high and it is strictly prohibited to put it into operation. Measured compressed air and cold water directly use the medium pressure. 2. Adjust the zero-point migration of the pressure transmitter. Since the water column in the pressure guiding pipe generates an additional pressure, the pressure indicator must have additional readings. It is necessary to zero-adjust this additional pressure, which is called zero-point migration. Specific methods: close the primary valve, open the pressure valve, and turn on the power supply. Open the pressure transmitter housing and adjust the migration screw so that the output of the pressure indicator is zero. 3. After the differential pressure transmitter is exhausted or drained, after the pressure guiding pipe is filled with water, sometimes a small amount of gas will accumulate in the pressure chamber of the differential pressure transmitter to affect the pressure guiding, and must be excluded...
