FIELD: measuring equipment.SUBSTANCE: invention relates to measurement equipment, in particular can be used for certification of measurement techniques and in measurement techniques for certification having water area and rail track test equipment and hydrodynamic tests of field and model objects thereto. Summary of invention consists in fact that along track of object movement Reed relays are placed in groups, which under control of magnetic field associated with object, stepwise change amplitude of electric signal in detected time row, within each group between Reed switches it is not required to sustain equal distance, between groups of Reed Relays it is not required to sustain equal distance, and it is assigned considerably larger than average distance between Reed switches in adjacent groups in some points of path of object, value of its velocity is determined by dividing distance covered at elapsed time, in other uses interpolation and extrapolation of measured values of speed.EFFECT: technical result is high information content and broader capabilities of use.1 cl, 5 dwg |
