Speed Meters: An Overview
Every day, each of us is faced with suchconcept, as "speed". This can be the speed of movement of a person or a mechanical means, wind or water, linear or rotating. There are many examples. AND
It turns out that there are hugea bunch of. Some are designed to measure the speed of movement of vehicles, others - to characterize the movement of liquids or gas through pipelines, the third - to measure the speed of the wind. However, there are a number of specific devices that have a very narrow direction. These are, for example, devices that measure the rate of blood clotting or meters for the speed of oscillation of hard surfaces in the range of ultrasonic frequencies. There are many others. In this article we will briefly review the main of such devices, as they are called and for what are intended.
So, let's begin our review:
1. Anemometer. This meteorological device is a meter of wind speed and gas flow. It consists of a blade or cup rotor, fixed on the axis, which is connected to the measuring mechanism.
2. Anemorumbometer. This device, like the previous one, is also intended for measuring the speed and direction of wind and gas.
3. Atmometer. This device is designed to measure the rate of evaporation of a liquid.
4. Velosimeters. These are meters of the speed of oscillation of solid surfaces in the ultrasonic range.
5. Turntable. This is a device designed to measure the speed of flow of rivers.
6. Hemodromograph. This is one of the first devices that have been used to determine the speed of movement of arterial blood.
7. Hemocoagulograph. This is a device designed to measure the speed of blood clotting.
8. Gyrotachometer - a mechanism for measuring angular velocities.
9. Deslerometer - a device designed to measure the reduction in the speed of various vehicles.
10. Microanemometer - a device used to measure wind speed.
11. Neurotrachometer. This is a mechanism for measuring speed, as well as the duration of successive or single limb movements.
12. Nefoscope - a measure of the speed and direction of the clouds.
13. Perspectometer. It has another name - "wave-meter-perspectometer". Used to measure various elements of waves: length, height, period, speed, and direction of propagation.
14. Pneumotachometer is a device for measuring the maximum space velocity of air streams with forced inspiration or expiration.
15. Radar - location device. In a particular case, it is used as a vehicle speed meter.
16. The radio reflexometer is a mechanism for remote measurement of the speed of a reflex reaction. Has the function of transmitting information over a radio channel.
17. Stopwatch - a household appliance for measuring the time of various processes.
18. The spectromotor is an astronomical device used to measure the difference in the radial values of the velocities of two stars. He uses the Doppler effect for a relative displacement of the spectral lines of stars in the spectra by combining photos on the screen.
19. Speedometer - a measure of the speed of movement of land vehicles, as well as the distance traveled.
20. Tachymeter - a device designed to measure the speed of the flow of liquids.
21. Tachogenerator - a mechanism that determines the speed of rotation.
22. Tachometer - the same as the previous mechanism, used to measure speed and speed.
23. Thermo-anemometer - a meter for the flow rate of liquids and gases.
24. Electrospirograph is a device used to determine and graphically record the value of the volumetric rate of exhalation or inspiration.
25. Effusiometer is a device designed for automatic detection and measurement of gas density.
Here we are in a nutshell and examined various speed meters and determined the purpose of each of them.
