根据GB/T 10180-2003《工业锅炉热工性能试验规程》规定,热水锅炉能效测试中的循环水量可以使用超声波流量计进行计量。超声波流量计按其测量原理可分为:传播速度差法、多普勒法、噪声法、波束偏移法等几种。传播速度差法又包括时差法、相差法和频差法~([1])。其中时差法超声流量计技术较成熟,能满足一般工业测量中准确度和可靠性的要求,使用较广泛,在工业锅炉能效
According to GB / T 10180-2003 “industrial boiler thermal performance test rules” provisions, hot water boiler energy efficiency test cycle of water can be measured using ultrasonic flow meter. Ultrasonic flowmeter according to its measurement principle can be divided into: propagation speed difference method, Doppler method, noise method, beam offset method, and so on. Spread speed difference method includes time difference method, phase difference method and frequency difference method ~ ([1]). One of the time difference ultrasonic flowmeter technology is more mature, to meet the accuracy and reliability of the general industrial measurement requirements, the use of a wider range of energy efficiency in industrial boilers
