TOKICO FLOWMETER, TOKICO OIL FLOWMETER a high accuracy displacement type flow meter composed of two roots and measures flow directly. Tokico Oil Flowmeter has little deterioration in the instrument accuracy because a couple of roots rotates with non-contact. This flow meter measures with high accuracy and wide flow range
