A consistometer is a long trough separated near one end by a spring-loaded gate. The normal way to use the Consistometer is to measure the distance a sample flows in a given time interval. To use the consistometer, you fill the gated section to the brim with your sample, then release the gate and time how long it takes the liquid to spread to a pre-determined notch on the trough. In effect, what you are doing is measuring the flow rate of your sample when no external force is acting on it.
