deltasonic® Ultrasonic Flowmeter

The new deltasonic® ultrasonic flowmeter.



Precision in the premium class segment at an affordable price.



deltasononic® WM for wall installation


pvt technology: if you are looking for quality and performance!



Advantages of deltasonic® WM:


  • Unique high accuracy: +/- 0,5 % of the reading for flowrates from 0.3 up to 12 m/s.(SI test bench certified accuracy = +/- 0.28% of the reading)


  • The Patented "PicofFly Quantenzeit Transit-Technologie“ is a special innovation of our deltasonic® series. By using two-dimensional space-time intercepts as time scale we can achieve an ultrasonic runtime nearly without any dead band: in a precision time range it is lower than 1 picosecond ~ 100 Ms


  • Therefore our deltasonic® series is highly accurate and mostly insensitive to bubbles and suspended solids.


  • With the help of state-of-the-art microelectronics in the low-voltage range less hardware components are needed. As a result highest precision and reliability can be achieved at  lowest power consumption.


  • Ultrasonic sensors up to 150°C are standard at pvt


  •  For switching between the various indicators you don’t have to scroll through the menu. You can obtain data very easily by using the touch keys on the front side of the device.


  •  Capacitive touch-sensitive buttons with almost unlimited life are used for operating all buttons. 


  • Due to the clear and user-friendly menu via the front buttons our deltasonic® series is very easy to work with and can be handled extremely comfortable. You can do the setup in just a few easy-to-follow steps
