Transit time measures the time differential between signals sent upstream and downstream.
Ultrasonic water flow meter circuit diagram.
The ultra sonic circuit is adjusted in such a way as to stay in balance as long the same as the output frequency of the transmitter.
There are two types of ultrasonic flow meter technologies.
Block diagram of basic flow meter figure 2 1 shows the flow meter concept block diagram.
Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it.
Both ultrasonic and traditional rotary meters benefit from low current consumption and integration that extend battery life and reduce system cost.

The measuring device employed is ieslabs ia uwm 2 gp30 dn20 ultrasonic flow sensing module.
For larger diameter pipes sensors with multiple paths are used.
That is a nebulizer.
The circuit works from 9 12 vdc and can be used with batteries or a power supply.
To check the working of the transmitter it is necessary to down convert the 40khz signal into 4khz to bring it in the audible range.
If there is some movement in the area covered by the ultrasonic emission the signal that is reflected back to the receiver becomes distorted and the circuit is thrown out of balance.
Version of ultrasonic flow meters so that we usually call it version 13 flow meter.
Doppler shift and transit time.
