*2 Fixed volume: For this method the cup is filled as normal, but timing is stopped after a fixed volume (50ml) of sample has passed through the cup orifice.įor optimum performance it is recommend to use the cups within a flow time range of 30 – 100 seconds, (table above refers) using the cups for sample flow above 100 to 300 seconds is not recommended as the linearity is not proportional to higher viscosity products. *1 Break point: The timing is taken at the first break in the continuous flow of the sample. The cups were originally designed for a flow time range of 30 – 300 seconds (break point*1 method) and 30 – 200 seconds (for fixed volume*2 method). Our density & viscosity measurement devices offer unbeatable performance for applications in alcohol concentration, API gravity, specific gravity and more.
