Instructions for use of the integrated orifice flow meter

Abstract: The instruction information of the integrated orifice flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. The integrated orifice flowmeter produced by our company is a high-range ratio differential pressure flow device composed of standard orifice plate and multi-parameter differential pressure transmitter, temperature transmitter and pressure transmitter. It can measure gas, steam, The flow of liquid and natural gas is widely used. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following are the details of the article on the use of the integrated orifice flowmeter. The integrated orifice flowmeter produced by our company is a high-range ratio differential pressure flow device composed of standard orifice plate and multi-parameter differential pressure transmitter, temperature transmitter and pressure transmitter. It can measure gas, steam, The flow of liquid and natural gas is widely used in process control and measurement in petroleum, chemical, metallurgy, electric power, heating, water supply and other fields. The following methods of use: 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 flow meter steam is not delivered in the pipeline, 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 full. You can also close the balance valve and the pressure valve, and open the valve once to introduce high-temperature steam to 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. 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. The specific method of electromagnetic flowmeter: close the primary valve, open the pressure valve, and turn on the power supply. Open the housing of the pressure transmitter 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, which must be eliminated. Unscrew the bolts at the lower part of the positive and negative pressure chambers to drain the fluid. Generally, instruments newly put into operation do not need to be drained. Check that there is no leakage in the pressure guiding pipeline system, close all valves, and it can be put into operation. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Instructions for the use of the integrated orifice flow meter'
