摘要： Liquid is supplied to a meter test stand at a uniform pressure, and the flow through the meters on the stand automatically is directed to each of three receptacles in sequence at three different flow rates during each test cycle. Level sensors in each receptacle actuate cycling controls and actuate sensing and recording components. The latter components monitor the rate of flow registration of the meters on test and provide an accurate comparison by percent of the measured flow rate to the actual flow rate. A high degree of accuracy is achieved through the use of a phase locked loop and digital control system which responds to the level sensing and cycling controls to provide a print-out of the comparison as a measure of accuracy of the meter at each such flow rate.

摘要： A compound meter assembly is provided having primary and secondary passageways housing a high flow rate meter and a low flow rate meter, respectively. A flow responsive first valve is disposed within the secondary passageway and moves to a substantially closed position when the liquid flow is increasing through the secondary passageway and exceeds a first predetermined rate. Upon substantial closing of the first valve the liquid flow is diverted from the secondary passageway to the primary passageway. A pressure responsive second valve is disposed within the primary passageway and is held in a closed position with respect to the primary passageway while the pressure drop is below a first predetermined amount across the meter. The second valve is forced to an open position when a substantial pressure impulse is momentarily exerted on the second valve. The pressure impulse is created when the liquid flow is diverted from the secondary passageway by substantial closing of the first valve. The second valve remains open due to the liquid flow through the primary passageway until such time as the flow rate drops below a second predetermined amount. After the pressure impulse has dissipated, the first valve will open again after the second valve has moved to its opened position.

摘要翻译：提供了具有分别容纳高流量计和低流量计的主要和次要通道的复合计量表组件。当液体流量通过次级通道增加并且超过第一预定速率时，流动响应的第一阀被设置在次级通道内并且移动到基本关闭的位置。在大致关闭第一阀时，液体流从次级通道转移到主通道。压力响应第二阀设置在主通道内并且相对于主通道保持在关闭位置，同时压力下降超过仪表的第一预定量。当在第二阀上施加相当大的压力脉冲时，第二阀被迫进入打开位置。当液体流通过第一阀的大量闭合从第二通道转移时产生压力脉冲。第二阀由于液体流过主通道而保持打开，直到流速下降到第二预定量的时间为止。在压力脉冲消散之后，第二个阀门在第二个阀门已经移动到其打开位置之后再次打开。
