Sound Speed (or sound velocity) refers to the speed of sound waves passing through an elastic medium. The actual speed depends upon the medium (for example, sound waves move faster through water than through air - because water has a higher density). The characteristics of the medium are also important factors, especially temperature.
An approximate sound speed in air (in meters per second) can be calculated using the following formula:
where (theta) is the temperature in degrees Celsius (°C).
Below is a list of materials that can be measured using an ultrasonic flow meter or clamp on flow meters:
