PCE-128 Series Flow Cup Meter
manufacturer calibrated / anodized aluminum / ISO / ASTM standardization

The PCE-128 ISO / ASTM viscometer or ISO / ASTM Flow Cup Meter uses gravity to measure the flow rate of a liquid. Under ideal conditions, flow rate is proportional to kinematic viscosity. Thus, an ISO / ASTM cup is used to determine the kinematic viscosity of fluids. The structure of an ISO / ASTM Flow Cup Meter is standardized according to BS EN ISO 2431 / ASTM D5125.

Basic operation
Cover the holes at the bottom of the orifice and pour in the liquid to be measured. Make sure that the Flow Cup Meter is completely filled. Use the glass plate to scrape off any excess liquid from the edge of the flow cup. Uncover the holes at the bottom of the orifice. Negative pressure will keep the liquid in the cup until you're ready to begin measuring. Active a stopwatch (not included) while simultaneously removing the glass plate from the cup horizontally. As soon as the flow is interrupted for the first time, stop the watch and write down the time.

Note: When using a Flow Cup Meter, it is very important to make sure that the instrument is cleaned thoroughly after each measurement, as residue in the orifice and cup can jeopardize the accuracy of future measurements. Scratches also can cause inaccurate results.
