一、超声波式热量表的结构采用超声波式流量传感器的热量表统称超声波式热量表,是利用超声波在流动流体中传播时,顺水流传播速度与逆水流传播速度差计算流体的流速,从而计算出液体流量。超声波热量表主要有两种:(1)直射式也叫对射式;(2)反射式也叫对流式。二、介质温度对热量计量的影响及温度补偿在热量表检测过程中,最大的影响因素就是温度。水温会产生超声波声速的变化,会使热量表发生
First, the structure of the ultrasonic heat meter Ultrasonic flow meter heat meter commonly known as ultrasonic heat meter is the use of ultrasonic waves in the flow of fluid, along the flow velocity and velocity of the inverse flow velocity calculation of the flow of fluid to calculate Liquid flow. Ultrasonic calorimeter mainly in two ways: (1) direct type is also called on the radio; (2) reflection is also called convection. Second, the impact of medium temperature on the heat metering and temperature compensation In the heat meter test process, the biggest impact is the temperature. Water temperature will produce ultrasonic sound velocity changes, will heat meter occurs
