One means for measuring torque is to mount the dynamometer housing so that it is free to turn except that it is restrained by a torque arm. Invented by British engineer William Froude in in response to a request by the Admiralty to produce a machine capable of absorbing and measuring the power of large naval engines,  water brake absorbers are relatively common today.

For example, the power produced by an engine,motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed RPM. A dynamometer can also be used to determine the torque and power required to operate a driven machine such as a pump. In that case, a motoring or drivingdynamometer is used. A dynamometer that is designed to be driven is called an absorption or passive dynamometer. A dynamometer that can either drive or absorb is called a universal or active dynamometer. In addition to being used to determine the torque or power characteristics of a machine under test MUT , dynamometers are employed in a number of other roles.
Oxford, UK:. J B Winther. Torque measurement is somewhat complicated since there are two machines in tandem - an inline torque transducer is the preferred method of torque measurement in this case. Pachchhao Designation: Asst.
Carousel Previous Carousel Next. Standard Atmospheric Pressure. Power and Torque Envelope 7. Vinay Rai.Absorbing dynamometers are not to be confused with "inertia" dynamometers, which calculate power solely by measuring power required to accelerate a known mass drive roller and provide no variable load to the prime mover. The actual rotational mass of the engine or engine xpplications vehicle in the case of a chassis dyno is not known and the variability of even tire mass will skew power results. An eddy-current or waterbrake dynamometer with electronic control combined with a variable frequency drive and AC induction motor is a commonly used configuration of this type. The dynamometer must be able to operate at any speed and load to any level of torque that the test requires.
Amruth Rao! Due to the low viscosity of air, this variety of dynamometer is inherently limited in the amount of torque that it can absorb. Box Hill Institute. System Price 9.
