Application of Boiler Steam Flowmeter in Industrial Production The application of the boiler steam flowmeter in industrial production is based on Karmen vortex street principle research and production. It is mainly used for the flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. Its characteristics are low pressure loss, large range, high precision, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable over a long period of time. The vortex flowmeter uses a piezo-electric stress sensor , which has high reliability and can operate in the operating temperature range of -20 °C to +250 °C. There are analog standard signals and digital pulse signals output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument. Boiler steam flow meter advantages: Advanced circuit, low power consumption, wide range, simple structure, small resistance loss, sturdiness and durability, wide application, long service life, stable operation, easy installation and debugging. Boiler steam flow meter Vortex flowmeter flow measurement technology and instrumentation applications generally have the following areas. Industrial production process The flow meter is one of the major instruments in process automation instrumentation and devices. It is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and daily life of the people. In various fields such as the national economy, it is an important tool for developing industrial and agricultural production, saving energy, improving product quality, and improving economic efficiency and management. It plays an important role in the national economy. In the process automation instrument and device, the flow meter has two major functions: as the total amount of the measuring instrument and the quantity of the measured material of the process automation control system. Boiler steam flow meter 1. The flow meter can be installed indoors or outdoors. Environmental conditions must meet the requirements. 2. The flowmeter should be installed in a pipeline that corresponds to its nominal path, whether it is horizontal, vertical or inclined (fluid flow from bottom to top). 3. Flowmeters should be avoided on pipes with mechanical vibrations. When vibration is unavoidable, a fixed support frame should be added to the straight pipe section approximately 2DN before and after the sensor . 4. The flowmeter should be installed in a place with strong electromagnetic field interference, heat radiation, corrosive gas, small space and inconvenient maintenance. 5 When the measured medium contains more impurities, a filter should be installed in addition to the required length of the straight section upstream of the flowmeter. 6. The upstream and downstream of the flowmeter should be equipped with a certain length of straight pipe section. The inner wall of the straight pipe section should be clean and smooth with no obvious bumps, scales, and peeling. Its length should meet the requirements of Figure 2. Inside the pipeline where the liquid sensor is installed, the liquid to be measured should be filled. 7. The inner diameter of the straight pipe section should be consistent with the diameter of the flowmeter as much as possible. If it is not consistent, a pipe diameter slightly larger than the flowmeter diameter should be used. The error should be ≤ 3% and not more than 5mm . Boiler steam flow meter selection 1 , precision function check The measuring accuracy classes and functions required to select and use the occasion meter level accuracy, so economical. Such as for trade settlement, product delivery and energy measurement occasion should choose some high level of accuracy, such as 1.0, 0.5, or higher levels; for process control applications, according to the control requirement to select a different accuracy level; some Just detect the process flow, do not need to do precise control and measurement occasions, you can choose a slightly lower accuracy level, such as 1.5 , 2.5 , or even 4.0 , then you can use low-cost plug-in vortex flowmeter. 2 , measurable media Measuring the flow rate of the medium, when the measurement range of the instrument with the aperture of the general media, the vortex flowmeter full scale flow rate can be measured medium flow rate 0.5 - In / s 12m range selection, the range is wide. Select Meter size (diameter) not necessarily the same as the process piping, the measurement should be considered in determining the flow rate range if the flow rate range, i.e., when the flow rate is low pipe, when the flow meter can not meet the requirements in this registration or measurement of the flow rate can not be guaranteed correct , you need to narrow the meter diameter, thereby improving the flow velocity in the executive, be satisfied with the measurement results. Intelligent vortex street steam flow meter selection In the saturated steam measurement, the VA type piezoelectric intelligent vortex street steam flow meter is used. Since the vortex flowmeter has a wide measurement range, in practical applications, it is generally considered that the flow rate of the saturated steam should not be lower than that of the vortex flowmeter. The lower limit, that is to say, the fluid velocity must not be less than 5m/s . According to the size of the steam, intelligent vortex street steam meters of different calibers are selected, and the diameter of the transmitter cannot be selected by the existing process pipeline caliber. 4 , pressure compensation pressure transmitter selection Due to the long saturated steam line and large pressure fluctuations, pressure compensation must be adopted. In consideration of the pressure, temperature, and density relationships, only pressure compensation can be used in the measurement. Because the saturated steam pressure of the pipeline is in the range of 0.3-0.7 MPa, the pressure The transmitter's range selection 1MPa can be. 5 , . Display instrument selection Display instrument intelligent flow indicator, with voltage compensation, instantaneous flow display and cumulative flow totalizer.
