DESIGN.。The 682 series piston flow meter is a true positive displacement flow meter that has an inline design consisting of three (3) reciprocating pistons operating within their respective measuring chambers, where each piston works in a manner similar to an automobile engine. The pistons are fitted to a wobble plate, which has a shaft extending from its upper surface and a valve pivot attached beneath it. The valve pivot drives a sliding valve from piston to piston as a known amount of product flows through each cylinder bore, controlling the sequence of events in a smooth mechanical motion.682系列活塞式流是一种真正的容积式流具有内嵌的包括三个3往复活塞在各的测室操作每个活塞在某种程度上类似于汽发动机工作的地方。活塞安在摆动板具有从其上延伸的和枢接在它的下。带动滑动活塞活塞作为已知的产品流经各气缸控制在一个平稳的机械动的事件序列。
