Measuring principle 

12.1

 

Ultrasound with piezo ceramics 

Flow sensor manufacturers have been working on alternative techniques to replace the mechanical 
principle. Research and development at Kamstrup has proven that ultrasonic measuring is the most viable 
solution. Based on microprocessor technology and piezo ceramics, ultrasonic measuring is not only 
accurate but also reliable. 

12.2

 

Principles 

The thickness of a piezo ceramic element changes when exposed to an electric field (voltage). When the 
element is mechanically affected, a corresponding electric charge is generated. Therefore, the piezo 
ceramic element can function as both sender and receiver.  

Within ultrasonic flow measuring there are two main principles: the transit time method and the Doppler 
method.  

The Doppler method bases on the frequency change, which occurs when sound is reflected by a moving 
particle. This is very similar to the effect you experience when a car drives by. The sound (the frequency) 
decreases when the car passes by. 

12.3

 

Transit time method 

The transit time method used in the water meter, utilizes the fact that it takes an ultrasonic signal sent in 
the opposite direction of the flow longer to travel from sender to receiver than a signal sent in the same 
direction as the flow.  

The transit time difference in a flow sensor is very small (nanoseconds). Therefore, the time difference is 
measured as a phase difference between the two 1 MHz sound signals in order to obtain the necessary 
accuracy. 

Illustrated on the diagram below.
