As we all know, the industrial flow measurement of large diameter, large flow measurement problems, this is because the general flow meter with the increase in diameter will bring manufacturing and transportation difficulties, cost increase, increase energy loss, Installation Not only these shortcomings, ultrasonic flowmeter can be avoided. Because all types of ultrasonic flowmeter can be installed outside the tube, non-contact flow measurement, instrument cost is basically nothing to do with the size of the measured pipe diameter, and other types of flowmeter with the caliber increases, the cost of a substantial increase, so the larger diameter ultrasound Flowmeter than the same function The function of other types of flowmeter price ratio superior. Is considered a good large diameter flow measurement instruments, Doppler ultrasonic flowmeter can measure the flow of two-phase medium, it can be used for sewer and sewage water and other dirty flow measurement. In the power plant, the use of portable ultrasonic flow meter to measure the turbine water, turbine water flow and other large diameter flow than the past, the skin off the tube much more convenient. Ultrasound is also used by flow gauges for gas measurement. Diameter range from 2cm to 5m, from a few meters wide open channel, culvert to 500m wide river can be applied.
