Example Sentences:

  • (1) The test takes a few seconds using one of many online speedometers, which include www.broadbandspeedchecker.co.uk , or www.speedtest.net .

  • (6) The headlamps are also damaged but the period gearstick, glovebox, running boards, speedometer and steering wheel remain intact.
  • (7) The same subjects intoxicated from alcohol accumulated significantly more accelerator, brake, signal, speedometer, and total errors than under normal conditions, whereas there was no significant difference in steering errors.
  • (8) Speed was recorded and controlled using a speedometer cart.
  • (9) He relates the analog display of information to that of an automobile speedometer or the hands of a standard wrist watch.
  • (10) This study compared the effects of simulated head-up display (HUD) and dashboard-mounted digital speedometers on key perceptual driving tasks in a simulated driving environment.
  • (11) The system is designed to be compatible with vehicles equipped with digital as well as standard speedometers and can be calibrated at any speed within its operating range.
  • (12) Subjects experiencing a "social marihuana high" accumulated significantly more speedometer errors than when under control conditions, whereas there were no significant differences in accelerator, brake, signal, steering, and total errors.
  • (13) Overall, a significant difference in performance between the two speedometer conditions indicated that subjects overestimated the target speed when they were not given access to their speedometer.
  • (14) Walking speed is recorded and controlled by means of a speedometer cart.
  • (15) Subjects were required to decelerate from a constant speed of 30 mph to a target speed of 20 mph under two conditions: using their speedometer and being deprived of its use.

Tachometer


Definition:

  • (n.) An instrument for measuring the velocity, or indicating changes in the velocity, of a moving body or substance.
  • (n.) An instrument for measuring the velocity of running water in a river or canal, consisting of a wheel with inclined vanes, which is turned by the current. The rotations of the wheel are recorded by clockwork.
  • (n.) An instrument for showing at any moment the speed of a revolving shaft, consisting of a delicate revolving conical pendulum which is driven by the shaft, and the action of which by change of speed moves a pointer which indicates the speed on a graduated dial.
  • (n.) An instrument for measuring the velocity of the blood; a haematachometer.

Example Sentences:
