"Basic operationCover 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.***Test stand sold separately. See also for recommendations.***"
"Gilson offers five sizes of Asphalt Institute Viscometers to determine viscosity of highly viscous materials such as bitumen at 140°F (60°C). The user measures elapsed time for a fixed volume of liquid to be drawn by vacuum through the graduated capillary tube. Time is multiplied by the viscometer constant to obtain absolute viscosity. Measurement requires a minimum sample size of 3ml and a bath depth of 7in (180mm). Certificate of calibration is supplied with each viscometer. Neoprene rubber holders to fit a 2in (51mm) diameter hole are ordered separately as PTA-100. Inquire if fixed metal holders preferred. Also see stopwatches and thermometers listed elsewhere. Est. Ship Wt.: 2lb (1kg)."
