测量液体、气体或粒体的流量时,通常不但需要流量的瞬时值,而且需要流量的积分值。在计算工艺材料的累计流量时广泛应用积算装置,在积算装置里,对从流量变送器来的电信号进行积分。不久前,流量积分的实现是将被测值转换成偏转角,然后将此角译成数字脉冲电码。当 When measuring the flow of a liquid, gas, or granule, it is usually not only the instantaneous value of the flow but also the integral of the flow. In the calculation of the cumulative flow of process materials widely used integrated device, in the integrated device, the signal from the flow transmitter to integrate. Not long ago, the flow integral was achieved by converting the measured value into a deflection angle, which was then translated into a digital pulse code. when
