Abstract
A system for measuring pump efficiency includes a pump configured to pump a fluid, a suction pipe disposed upstream of a suction side of the pump, a discharge pipe disposed downstream of a discharge side of the pump, a first pipe section disposed between the suction pipe and the suction side of the pump, and a second pipe section disposed between the discharge pipe and the discharge side of the pump. Each of the first pipe section and the second pipe section includes a temperature sensing pipe liner configured to measure a temperature of the fluid in the first pipe section, and a thermal insulator disposed radially outward of the temperature sensing pipe liner.
