An instrument used for measuring the distance of an object from an observer; as, a telescope with a micrometer for measuring the apparent diameter of an object whose real dimensions are known.
A measuring instrument which sends the information obtained from its sensors by radio to a distant station, usually to be recorded there; also, the complete system including measuring instrument, transmitter, and receiver. Such instruments are used, for example, to measure conditions in space or in other locations difficult of access for humans observers, or merely to allow one observer to monitor conditions in many places simultaneously.
any scientific instrument for observing events at a distance and transmitting the information back to the observer
A scale on the dial or bezel of a chronograph that - in conjunction with the second hand of the chronograph - may be used to measure the distance of an object from its observer by measuring how long it takes sound to travel that distance. One application of a telemeter would be determining the distance of a storm from its observer. See uses of a chronograph in the Instructions section of this web-site for an example.
Calculates the distance of an object from the observer by measuring the time taken for the sound to travel the distance. Consists of a chronograph with a special scale, usually on the outer edge of the watch?s face.
Stopwatch or chronograph function with a scale that measures the distance of something from the wearer of the watch through the amount of time it takes sound to travel.
("tel EH meh ter") A telemeter determines the distance of an object from the observer by measuring how long it takes sound to travel that distance. Like a tachymeter (see "tachymeter"), it consists of a stopwatch or chronograph and a special scale, usually on the outermost edge of the watch face.
A telemeter determines the distance of an object from the observer by measuring how long it takes sound to travel that distance. Like a tachymeter, it consists of a stopwatch, or chronograph, and a special scale, usually on the outermost edge of the watch face. 30-Minute Recorder (or register): A subdial on a chronograph that can time periods of up to 30 minutes.
The measuring, transmitting, receiving, and indicating apparatus for obtaining the value of a quantity at a distance.
A chronograph scale allowing the measurement of distance. For example, the wearer can figure the distance of a lightning strike by pressing a button when the lightning is seen, and again when the thunder is heard, to determine the storm’s distance.
A telemeter determines the distance of an object from the observer by measuring how long it takes sound to travel that distance. Like a tachymeter (see "tachymeter"), it consists of a stopwatch, or chronograph, and a special scale either imprinted on the crystal ring on the inside of the case but usually on the top outside of the case.
By means of the telemeter scale, it is possible to measure the distance of a phenomenon that is both visible and audible. The chronograph hand is released at the instant the phenomenon is seen; it is stopped when the sound is heard, and its position on the scale shows, at a glance, the distance in kilometers or miles separating the phenomenon from the observer. Calibration is based upon the speed at which sound travels through the air, viz. approximately 340 meters or 1,115 feet per second. During a thunderstorm, the time that has elapsed between the flash of lightning and the sound of the thunder is registered on the chronograph scale.
the kind of scale measured in kilometers or miles used in conjunction with chronograph, that determines the distance through sound.
A timer or chronograph with a graduated dial or bezel which enables you to measure distance by measuring the time elapsed at a fixed speed. I.E. The speed of sound.
A watch function that finds the distance of an object from the wearer by measuring how long it takes sound to travel the distance. Like a tachometer , a telemeter consists of a stopwatch function and a special on the dial of a chronograph .
Another watch function that finds the distance of an object from the wearer by measuring how long it take sound to travel a distance. Like a tachymeter, a telemeter consists of a stopwatch function and special scale on the dial of a chronograph.
