Drinktec 2025: Allengra presents new ultrasonic micro flow sensor

At this year’s Drinktec in Munich (September 15–19, 2025), Allengra will present the latest generation of its Micro Flow Sensor, specially developed for applications in the beverage industry. Whether in fully automatic coffee machines, water dispensers, beer taps, or cocktail systems – the sensor ensures reliable dosing, maximum hygiene, and versatile integration options. It is a key component for the next generation of automated beverage systems.

With the ongoing labour shortage in hospitality and growing expectations regarding speed and quality, automation in beverage dispensing is becoming increasingly important. The technical requirements are clear: systems must operate with precision, hygiene, and reliability – across a wide range of fluids, temperature variations, and within limited installation space.

Technical highlights include measurement accuracy: ±2% of measured value; food-grade design compliant with EU regulations 1935/2004 and 10/2011, and dead-space-free design for easy cleaning.

The unit is designed as more than just a flow sensor as the ultrasonic technology used enables additional features that offers air bubble detection, foam detection, media recognition, and temperature dynamics. Combined with high-precision PT1000 thermometers, this enables dynamic and precise temperature control – ideal for applications like coffee preparation. These added functionalities enhance process control and help prevent dispensing and mixing errors

Allengra’s Micro Flow Sensor is a reliable and future-proof solution for manufacturers of beverage systems, combining technological precision with practical design.

The sensor delivers highly accurate flow and temperature measurements, even at low flow rates or rapidly changing conditions. Its ultrasonic measuring technology enables completely contactless operation – with no moving parts and no direct contact between the sensor components and the medium. This ensures wear-free and maintenance-free performance in a hygienic and easy-to-clean design.

The Micro Flow Sensor can be integrated into existing beverage systems– as a standard component or a customised OEM version. Allengra offers tailored developments for customers with specific requirements regarding installation space, geometry, or interfaces. This makes the sensors ideal for series production, modular platforms, or highly automated system solutions.
