Meaning of metrograph | Babel Free

Definitions

1. An instrument attached to a locomotive for recording its speed and the number and duration of its stops.
2. A device used to measure the flow and velocity of liquids.
3. Any of various devices that continuously record several meteorological phenomena; a radiosonde or one of its precursors.
4. A device that uses reflection holograms to accurately measure three-dimensional objects, used primarily in orthodontics.

Examples

“Metrographs have been devised for counting the revolutions and speed of locomotive wheels.”

“Now, equipment is available today where you can use teletype, punch cards, use a metrograph machine, or a thousand ways.”

“Represented by R.W. Sparling, and C. F. Sherwood, exhibited the Sparling line of main line meters and metrograph recording instruments.”

“The automatic records of the sunshine recorder, the anemometer and the wind vane, are registered on one instrument, which is called a metrograph or improved triple register.”

“The metrograph temperature sensor and the two mercury thermometers were backed up by temperature readings from nickel iron resistance thermometers and reported temperature readings from Buckley Air National Guard Base Weather Station.”

“The government's contribution to the radiosonde dates back to the "airborne metrograph" of the 1920's. This was a mechanical device that recorded temperature, humidity, and pressure.”

“Since the 1930s, the government would use radio metrographs to monitor the weather.”

“With the metrograph, the hologram is fixed and the point of light can be moved in the three orthogonal directions.”

“[…] is shown for the first time that with reflection holograms of orthodontic dental casts, measurements can be made of the quantities required for treatment assessment, to within +-0.2 mm, using a reflex metrograph.”

“To relate the subjective assessment of the Goslon Yardstick to objective measurement, overjet, overbite, incisor angulation, and various arch form and crossbite relationships were masured on the same series of study casts using a reflex metrograph.”
