Features:      

Ultrasonic flow sensors have no moving parts in the volume flow, this makes them almost wear free and 
noiseless. They measure the flow by using the transit time principle, one ultrasonic signal is launched in the flow 
direction and one against the flow direction. The flow rate is concluded by the delay time measured, this 
information is then transmitted to the calculator by the way of electronic pulses.   
 
The calculator uses the latest innovative technology to calculate heat usage from heating systems. With its 
dynamic measuring cycle even the smallest energy consumptions are reliably collected. The large multifunction 
display permanently shows the heat consumption total, and by using the button is it possible to scroll through 
the display to show all data.
