Is a hydraulic dynamometer more reliable than a water-brake dyno?
Dynamometers have been around since the early 1900s and use many methods for inducing a braking force on the device under test. Water, hydraulic, eddy current and others are common forms of braking. Hydraulics have been found to be a more stable fluid for measuring engine characteristics. More stability means less breakdown, lower maintenance costs and better testing results. Hydraulic fluid based dynos provides more consistent results and longer life than water based dynamometers.
