n: a dilatant. or inverted plastic, fluid is usually made up of a high concentration of well-dispersed solids that exhibits a nonlinear consistency curve passing through the origin. The apparent viscosity increases instantaneously with increasing rate of shear. The yield point, as determined by conventional calculations from the direct-indicating viscometer readings, is negative;however, the true yield point is zero.

n: This fluid is one of non-Newtonian flow patterns whose unique feature
is that once the fluid is subjected to force,it will start flowing without any gel strength.




a well dispersed, high solids content liquid that has very high apparent viscosity with any applied shear.

n: the difference between the opening meter reading and the closing meter reading.

n: the change in meter reading that occurs during receipt or delivery of a liquid product.

n: used to reduce current or voltage to a known proportion of that in the circuit. A meter is attached to the reduced voltage or current and the voltage or current in the circuit is computed from the meter reading.

n: 1. the operation by which meter readings are compared with an accepted standard.2. adjustment of a meter so that its readings conform to a standard.

n: the instantaneous display of the number of units of volume or equivalent thereof read directly from a meter register.

n pi: 1. values observed at temperatures other than the specified reference temperature. 2. hydrometer readings observed at temperatures other than the specified reference temperature.

n: in meter proving, the method wherein the opening and closing meter readings of the test run are determined at flowing conditions. Compare standing start-and-stop method.

n: in meter proving, when the opening and closing meter readings of the test run are determined at no-flow conditions. Compare running start-and-stop method.
