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.
Free Webinar with Q&A: Development of Standards and Their Importance to Materials Testing
Would you like to learn more about how standards are developed to improve the quality of products we use every day? Are you interested in how standards apply to materials testing? And would you like to know how you can get involved in the development of these standards? ZwickRoell invites you to join us for this webinar hosted by our aplications engineer and ASTM committee member, Melanie Hoffman.
