1 影响流量计系数的因素分析当以流量计进行交接计量时 ,在运行工艺条件下 ,由于温度、压力、粘度等因素的改变均会影响计量的体积。由于受生产工艺的限制 ,很多时间流量计检定时的温度、压力与生产运行时的温度、压力不同 ,其中温度是流量计计量中最有影响的一个参数。当生产 A factor affecting the flow meter factor analysis When the flow meter to measure the transfer, under the operating conditions, due to changes in temperature, pressure, viscosity and other factors will affect the measured volume. Due to the limitations of the production process, many times when the flowmeter test temperature, pressure and production run temperature, pressure is different, of which the temperature is the most influential measurement of a flowmeter parameters. When produced
