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 transit time measured is directly and exactly related to the velocity of the liquid in the pipe.

OUR COMPANY

Allengra GmbH was founded in 2005 by Raul Junker. The main idea was to use and improve an innovative technology – the Ultrasonic Measuring Technology.

Our company profile always covered a wide area, from ideas and market-necessities, to R&D – hardware, software and design, prototyping and up to mass – production.

The dynamic Allengra team is always challenging itself to integrate new innovative ideas into its customers’ products. With the many different test benches Allengra built in the past, the flow sensors evolved into basic equipment that combined more or less the same elements: a pipe pressure sensor, one for differential pressure, combined with a flow sensor for the sensor static pressure, a temperature sensor and a sensor for the flow and the volume of the medium, as well as an actuator and a valve for flow control.
