A precision piston transducer ensures accurate measurement of piston stroke when determining MVR. The contact point is very close to the piston, minimizing possible angle errors from the outset. The accuracy with which the flow rate is determined in Method B depends on the synchronization of the time-travel data pairs and on the accuracy of the time determination. As both measured quantities (time and travel) are available in digital form from the outset, there is no need for analog to digital conversion. This also eliminates synchronization errors. Quartz accurate time measurement also enables measurement of materials with high flow-rates.
