(n.) An instrument attached to the wheel of a vehicle, to measure the distance traversed; also, a wheel used by surveyors, which registers the miles and rods traversed.
Example Sentences:
(1) A cart equipped with an odometer, for measuring distance, and a hydraulic dynamometer, for measuring draught force, was used.
(2) A wagon equipped with an odometer and a hydraulic dynamometer was used for measuring distance and draught force.
(3) Voluntary exercise was provided by free access to running wheels fitted with odometers.
(4) The hydrostatic pressure required to reduce the water content of rabbit feces in an odometer from greater than 80 to less than 65% was approximately 5 atm.
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:
(1) Speed settings were recorded as percentages of the servomechanism's maximum tachometer feedback voltage (10 to 100% Vfb max).
(2) Speed settings were standardized percentages of each machine's maximum tachometer feedback voltage (0 to 100% Vfb max).
(3) Displays of a tachometer and a special timing device are large enough to be clearly visible on the film.
(4) A Grass polygraph and tachometer were used to record the applied pulses and nodal firing rates; simultaneous magnetic tape recordings were obtained and used for data analysis.
(5) This report describes a safe and inexpensive method of modifying a centrifuge lid so that calibration of the machine with a photoelectric tachometer is a simple and safe procedure.
