In this paper is offered hydraulic sensor to measure the kinematic, power and energy parameters. Developed scheme and the principles of the hydraulic sensor. Identification on the special flow lab with real modes of the device is determined by its performance in different conditions. Approximation of the results received dependences flow and pressure drop characteristics on the speed and entrance pressure, allowed more correctly assess and describe the operation of the hydraulic sensor over the entire range of speed and entrance pressure.
Keywords: hydraulic sensor, spilling method, flow and pressure drop characteristics, multifunction control unit.
