deltawave - acoustic flowmeter - 2

deltawave provides precise measurement for all hydrological tasks and can be used in virtually any application: in filled and partially-filled pipes, open channels, canals and rivers. deltawave functions even under extreme conditions, maintenance and calibration-free and reliably. The measurement system continuously monitors itself, and its multi-channel design ensures redundant safety. Using just one deltawave flow transmitter allows you to cover up to 4 independent measurement sites. deltawave is in use in a wide variety of industrial settings: Water and Wastewater Management Special...

Innovative measurement process, precise evaluation Correlation method permits measurement under most difficult requirements Ultrasonic signals are disturbed by a large number of influencing factors; this includes EMC radiation, gas or solid impurity loading, machine noise etc. For conventional ultrasonic devices to be able to reliably pick out the ultrasonic signals in this "ambient noise", the signal amplitude must be a multiple of the noise . For deltawave, systec Controls has developed a new kind of evaluation method, which finds the ultrasonic signals even if the amplitude of the noise...

Maintenance-free, no culverts, no long approach paths Intelligent Evaluation Transit time measurement with highest resolution of flow speed deltawave's electronics measure the transit time difference of the ultrasonic signals running with and against the direction of flow with astonishing precision . The evaluation technology developed by systec Controls boasts a resolution of up to< 30 psec. nated. This becomes possible thanks to the extremely powerful ultrasonic transducers, which can cleanly convert such encoded transmission signals into ultrasonic signals. Consequently, deltawave...

Proven measurement process, simple installation The calculation of flow speed is based on the ultrasonic transit time process: two ultrasonic transducers emit sound waves into the medium at an angle a (15- 75°) . The two transducers function reciprocally as receiver and transmitter, and together form a so-called acoustic path. This type of transducer pair combines to form an acoustic path. The ultrasonic signals (T1) emitted by the transducer positioned upstream are accelerated by the flow, while the ultrasonic signals (T2) from the transducer located downstream are delayed . The transit...

deltawave Technology Installation in open channels The transducers can be installed directly on the surface of the channel or on special mounting rails which enables them to be pulled under operational conditions. Connecting a level measurement device (4 .. 20 mA) makes possible correct discharge calculation under changing level values. Installation in piping In filled pipes, the transducers are either introduced into the inside of the tube through welding sockets or installed internally, e .g . by means of a clamping ring . Using welding sockets in the Quicklock construction form or an...

Self-explanatory, convenient, safe and able to be monitored over the internet ily prepared for measurement, even for very complex applications. The accompanying Windows software enables intuitive and largely self-explan- atory parameterization. After finalizing the parameters, the lat- laptop on a common memory stick and loaded to the device. Simply insert the stick into deltawave - the parameters are then copied fully automatically. Irk- some maneuvering of the laptop under often rough conditions at the measure ment location is thus eliminated. Even updates, software enhancements or...

Transducer Testing Using the transducer verification function, individual transducers can be tested in dry conditions (e.g . function checking prior to installation and/or after installation and prior to flooding). Simply hold the small plexiglass testing block against the transducer and initiate the transducer test via deltawave's touchscreen . The signals reflected from the testing block are then evaluated by deltawave. The optical display makes it a simple task to determine at a glance whether the transducer is functioning fully correctly. Costly dewatering/dismantling of the transducers...
