PROBLEM TO BE SOLVED: To precisely measure a flow rate when a low-fluidity liquid is transported. SOLUTION: The measuring apparatus is provided with a load cell 14 and a load cell 16 which measure a change in the weight within a prescribed time of a dehydrated cake 2 stored in an acceptance hopper 4 or a delivery hopper 12 by a low-fluidity-liquid transport pump 1, a proximity sensor 19 which measures the number of strokes of a piston 9 at the pump 1, and a computing means 20 which finds the volume efficiency of the pump 1 on the basis of measured data on the load cells 14, 16 and the proximity sensor 19.
