ABSTRACT:
A device is provided for use in measuring acceleration and deceleration of a rotating body. The device includes a housing having wall means which define an endless flow path. The housing is rotatable about an axis which passes through the center of or is eccentric to the housing. The flow path includes a plurality of interconnected chambers with capillary passages therebetween. Electrically conductive flow medium is contained in the path and is adapted to travel about the path upon rotation of the housing about the axis. Monitoring means are provided at preselected positions about the path for sensing the presence or absence of medium at said positions and, further, to measure the amount of medium in each of said chambers.
