Every day, each of us is faced with such a thing as "speed". This can be the speed of movement of a person or a mechanical means, wind or water, linear or rotation. There are many examples. And
each indicator needs a separate measurement method. This article provides an overview of devices such as speed meters.
It turns out that there are a lot of such devices. Some are designed to measure the speed of vehicles, others - to characterize the movement of liquids or gases through pipelines, and others - to measure wind speed. 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 coagulation or meters of the speed of oscillation of solid surfaces in the ultrasonic frequency range. There are many others. In this article, we will briefly review the main of these devices, what they are called and what they are intended for.
So let's start our review:
1. Anemometer. This meteorological device is a meterwind speed and gas flows. It consists of a paddle or cup wheel mounted on an axle that is connected to a 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 is a device designed to measure the rate of evaporation of a liquid.
4. Velocimeters. These are ultrasonic vibration speed meters for hard surfaces.
5. Pinwheel. This is a device designed to measure the speed of the flow of rivers.
6. Hemodromograph. This is one of the first devices that began to be used to determine the speed of arterial blood flow.
7. Hemocoagulograph. This is a device designed to measure the rate of blood clotting.
8. A gyro tachometer is a mechanism for measuring angular speeds.
9. A decelerometer is a device designed to measure the speed reduction of various vehicles.
10. A micro anemometer is a device used to measure wind speed.
11. Neurotachometer. This is a mechanism used to measure the speed, as well as the duration of successive or single limb movements.
12. Nephoscope - measuring the speed and direction of movement of clouds.
13. Perspectometer. It has another name - "wavemeter-perspectometer". Used to measure various elements of waves: length, height, period, speed, and direction of propagation.
14. Pneumotachometer - a device for measuring the maximum volumetric air flow rate during forced inspiration or expiration.
15. Radar is a radar device. In a particular case, it is used as a vehicle speed meter.
16. Radio reflexometer - a mechanism for remote measurement of the speed of the reflex reaction. It has the function of transmitting information via radio.
17. A stopwatch is a household appliance for measuring the time of various processes.
18. A spectrocompactor is an astronomical instrument used to measure the difference between the radial values of the velocities of two stars. It uses the Doppler effect of the relative shift of the spectral lines of stars in the spectra by superimposing photographs on the screen.
19. Speedometer - a measure of the speed of movement of land vehicles, as well as the distance traveled.
20. A tachymeter is a device designed to measure the flow rate of liquids.
21. Tachogenerator - a mechanism that determines the speed of rotation.
22. Tachometer - just like the previous mechanism, it is used to measure speed and speed.
23. Hot-wire anemometer - measuring the flow velocity of liquids and gases.
24. An electrospirograph is a device used to determine and graphically record the value of the volumetric rate of exhalation or inhalation.
25. Effusiometer is a device designed for automatic registration and measurement of gas density.
Here we are in a nutshell and examined various speed meters anddetermined the purpose of each of them.
