Guide for use and maintenance of integrated orifice flowmeter in textile industry

Due to the development of the textile industry, the integrated orifice flowmeter plays an increasingly important role in the textile industry. The following will share with you the guide for the use and maintenance of the integrated orifice flowmeter in the textile industry. The integrated orifice flowmeter is a high-range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter. It can measure the flow of gas, steam, liquid and lead, and is widely used in petroleum, chemical, metallurgy , process control and measurement in the fields of electricity, heating, water supply, textiles, etc. The throttling device, also known as the differential pressure flowmeter, is composed of a primary detection part and a secondary device, which is widely used in the flow measurement of gas, steam and liquid. It has the characteristics of simple structure, convenient maintenance and stable performance. Precautions for the use of the integrated orifice flowmeter: 1. Measurement accuracy. Whether the design parameters of the integrated orifice flowmeter are consistent with the actual parameters is directly related to the measurement accuracy. When the standard orifice plate is put into use, if the measured parameters are within the range of the design parameters, the measurement accuracy will generally not exceed the design calculation accuracy; but if the measured parameters are far from the design parameter range (assuming the standard orifice plate and the differential pressure transmitter) Selection, manufacture, and installation all meet the requirements), it may be that the provided design parameters are wrong, the design parameters should be changed, and the standard orifice plate should be redesigned and calculated. 2. Configure the isolator. When measuring the flow of dirty fluids, be sure to configure a settler or isolator. Pay attention to how to reasonably select the position of the inlet, outlet and sewage outlet of the pressure guiding fluid to achieve the purpose of sewage discharge. 3. Reasonable selection of isolators. When measuring the flow rate of corrosive fluids, it is necessary to select the appropriate isolator, select the appropriate isolator according to the specific gravity of the medium, and pay attention to the reasonable selection of the isolator and the inlet of the fluid to be measured. 4. Check the pressure tube. For a new meter or an integrated orifice flowmeter that is reactivated after a period of inactivity, the pressure-inducing pipeline should be checked for blockage or leakage before being put into use; the pressure-inducing pipeline should be filled with clean water or other guides for liquid media. Pressurized liquid, pay attention to the gas mixed in the discharge pipeline, and pay attention to the accumulation of liquid in the discharge pipeline for gaseous media. Maintenance guide for the integrated orifice flowmeter: 1. Always check the zero point. The zero point of the differential pressure transmitter sometimes drifts, which affects the measurement accuracy (especially when the flow rate is small and the differential pressure is close to the lower limit value). The zero point should be checked frequently. Differential pressure transmitter can extend the zero calibration period to 1 year according to experience. We recommend to use the differential pressure transmitter of central control to reduce the workload of daily maintenance. 2. Regular maintenance. The daily maintenance work is mainly to remove the scale in the settler or isolator, and regularly discharge it from the sewage outlet. When the measured medium is high temperature and high pressure corrosive or toxic fluid, pay attention to safety when removing it. The above is the guide for the use and maintenance of the integrated orifice flowmeter in the textile industry, hoping to be helpful for the application in the textile industry.
