The TCS model 682 series positive displacement piston flow meter presented by Veederline is designed to accurately measure liquids within the adhesives, agricultural, aviation, chemical, food processing, paint, petrochemical, petroleum, pharmaceutical, printing, textiles and other industries requiring precise liquid flow measurement. The TCS/Tokheim model 682 PD flow meter comes with Veeder-Root model 7887 register.
The TCS model 682 series flow meter is a positive displacement meter that has an inline design consisting of three 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 cylindrical bore, controlling the sequence of events in a smooth mechanical motion. This smooth mechanical motion is then transferred through the calibrator to the register.
