蒸汽质量超声流量计的应用

针对Shell煤气化汽包大小室间流量测量的重要性及工况的特殊性(高温,高压,双向流量),提出采用三声道蒸汽质量超声波流量计作为测量仪表,详细介绍了蒸汽质量超声流量计的测量原理、特点、安装技术要求和应用注意事项,并和其他流量计的技术参数进行了对比,证明其具有双向流量测量、无压力降、维护少、范围度宽、适用温度高等特点。给出了其在项目中的成功应用案例。

Application of Steam Mass Ultrasonic Flow-meter

The steam flow between big and small chamber of Shell’s coal gasification drum is a key parameter for controlling the temperature in the gasification oven,it is of great importance to select one suitable flow meter for the whole coal gasification process.The measurement principle,characteristic,technological requirements of installation and application notes of three-channel steam mass ultrasonic flow-meter are introduced according to the application case on Shell coal gasification drum.Its technical parameters are compared with those of other flow-meters,which proves that it has the characteristics of bidirectional flow measurement,elimination of pressure drop,low maintenance,wide range and high suitable temperature,etc.
