Facility
Allengra GmbH was founded in 2005. The main idea was to use and improve an innovative technology - the Ultrasonic Measuring technology.
Our profile covers a wide area, from ideas, market-necessities, to R&D, prototyping and up to mass-production.
One of our main goals is to serve our clients-, and aiming their full satisfaction. Therefore we focus on quality, costs and time.
Our philosophy is: Time is the decisive element.
Yours, Raul Junker - founder of Allengra GmbH

Ultrasonic Technology

Our products use the Ultrasonic Measuring Technology. The measurement is realized by two piezo transducers based on the "time of flight" principle (TOF). The piezo transducers are controlled by an electronic board (PCB). The flow meter operates by alternately transmitting and receiving a burst of ultrasonic sound between the two transducers and measuring the transit time that it takes for the sound to travel between the two transducers. The fluid influences the speed of the sound signal depending on the direction. The difference in the measured transit time is directly and exactly related to the velocity of the liquid in the pipe.
