The working principle of an electronic energy meter is a device that measures the electronic energy consumed (usually in KWh). It is often incased in glass and has a disk that rotates that measures the amount of power (product of current and voltage) the flows through the meter. The rotation is then integrated over time either by mechanical dials or an electronic digital counter to determine the total energy used.
To simplify reading, many modern ones also contain a type of radio transponder that can be interrogated remotely from the meter reader's vehicle so he/she no longer has to find, read, and write down the value on every meter on his route.
CLAMP METER WORKS WITH THE PRINCIPLE OF HALL EFFECT..
basic principle of analogue clamp meter
1)what is the relation of total dissolved solid and conductivity of water? 2)What is the difference of the conductivity of treated water and raw water?
Wattmeters are used for the measurement of dielectric power loss. It is also useful for the calibration of commercial forms of wattmeter and watt-hour meter in laboratories.

By stop using the electricity
this is good to know that there is a way i can find somthing usuful for mi studies
trivector meters are used to measure kVAh and also kVA of maximum demand.it has a kwh meter and reactive kvah meter in a case with special summator mounted between them.

it principle denpend on what kind of flow meter. example, magnetic flow meter, it use magnetic force to measuring or coriolis flow meter which is use vibrated capilary tube as sensor. or more info you might watch on youtube.
