The Froude F-series range of hydraulic dynamometers also referred to as water brakes have been designed to be compact, robust and to allow easy maintenance.
Some of these models are available with a streamlined, fabricated base. These engine dynos are fitted with two half couplings which, with the rotor, are oil injected onto the shaft.
The standard machines run in grease lubricated rolling element bearings.

The hydraulic dynamometer working compartment consists of special semi-circular shaped vanes cast into stainless steel rotor and stators. Water flowing in a toroidal vortex pattern around these vanes creates hernan torque reaction through the dynamometer casing which is resisted and measured by a precision load cell. The dynamometer load is controlled by a ‘butterfly’ water outlet valve, operated by a closed loop electro-hydraulic servo system.
The power absorbed by the dynamometer is carried away by the water in the form of heat. As standard, the F type machines are fitted with two half couplings allowing connection at either end.
These, along with the rotor, are oil injected on to the main shaft, thus eliminating stress raising keyways. Grease heeann is replaced by the optional ‘oil mist’ system for the High Speed versions.
