Intelligent vortex flowmeterIt is a commonly used flowmeter product designed specifically for measuring saturated steam, which can automatically compensate for the density of saturated steam. Integrate flow and temperature compensation sensors into one. The sensing head is a field detachable body that can be replaced without affecting the fluid flow inside the pipeline. Through integrated temperature compensation, the instantaneous mass flow rate, cumulative flow rate, temperature, pressure, etc. of saturated steam can be displayed. The steam temperature can also be manually set, and the temperature and vortex sensor head can be replaced without stopping the fluid inside the tube. It can be widely used for measuring the flow of water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, compressed air, saturated and superheated steam, natural gas, and various media in large, medium, and small pipelines.
Intelligent vortex flowmeterThe selection is influenced by many factors such as the display accuracy, flow range, and output current of the tested fluid medium. In the selection process, the following five steps can be followed:
(1) The higher the precision level, the higher the price, and it is necessary to choose correctly to achieve cost-effectiveness: for trade settlement and other occasions, advanced instruments such as 1.0 or 0.5 can be used; In situations where precise control and measurement are not required, low precision instruments such as 2.5-level instruments can be selected, and even plug-in vortex flowmeters can be chosen;
(2) Each type of vortex flowmeter has a measurement range, and the instrument diameter needs to be consistent with the pipeline. The instrument specifications may not necessarily be the same as the process pipeline, and it is determined whether the measurement flow range is within the flow rate range;
(3) In practical applications, the selection of transmitters generally considers that the flow rate of saturated steam measured should not be lower than the lower limit of the vortex flowmeter (5m/s), and then the transmitter diameter should be selected according to the steam consumption, rather than the existing process pipeline diameter;
(4) When the pipeline is long and the pressure fluctuation is large, the selection of pressure compensation pressure transmitter requires measurement compensation. Considering the correspondence between pressure, temperature, and density, only pressure compensation is needed;
(5) The intelligent flow display instrument has functions such as voltage stabilization compensation, instantaneous flow display, and cumulative flow calculation. It can be combined with the temperature and pressure compensation integrated with the fourth item.
