Generally, three methods are used for making stream flow measurements:
i) Current meter.
ii) Dilution techniques.
iii) Indirect methods.
The new modern techniques for stream flow measurement are:
i) Electromagnetic flow meter
ii) Sounding weight
iii) Echo-depth recorder
Hygrometer is an instrument used for measuring the amount of humidity and water vapour in the atmosphere, soil and in confined spaces.
