deltawave - Ultrasonic flow meter for filled and partially filled pipes, open channels and rivers


new signal analysis

Our new measuring system deltawave is not only a precise flowmeter for open channels,filles and partially filled pipes but also a temperature meter and a flow profile analysis tool.


Due to the unique patent pending signal analysis deltawave works under extreme conditions, maintenance-free, calibration-free and reliably. The measurement system monitors itself continously and the multi-channel property ensures redundant safety.

With only one deltawave, you can realize up to four independent measurement sites, significantly reducing the equipment cost. This feature, combined with the high accuracy up to 0.5% makes deltawave to one of the most powerful measuring systems.



New ultrasonic signal analysis for higher meter performance

Ultrasonic signals are disturbed by a large number of influences: EMC, gas or solid loading, machine noise etc. Systec has developed a new kind of evaluation method to ensure an accurate and reliable measurement even under extreme conditions. Because of the signal correlation analysis the ultrasonic signals are cognizable even if the the amplitude of the noise is a multiple of the signal amplitude. That and the high time-resolution of the transducers are the reasons that DELTAWAVE measures even the smalles flow speeds reliably and accurate.


Optimize your process costs! Sewage water billing flow meter application:

waste water flow meter

You do not need expensive and lavish construction work any longer.


Wether huge culverts nor big MID’s or Venturis are needed. The ultrasonic transducers of DELTAWAVE are simply mounted directly on the channel wall or pipe.

We develop and produce individual mounting solutions for your individual application. Uninterruptible mounting and servicing is possible for the very most applications. Using established mounting rails – as shown in the picture – is only one solution. We look forward to discuss you measuring challenge.

Therefor, longsome and expensive standstills will be avoided from the beginning.
