About Us
Building trust through excellence
From a founder's vision in 2005 to becoming the global reference for ultrasonic flow metering solutions
Allengra was founded in 2005 by Raul Junker with a clear idea in his mind having worked in Flow Metering for many years, as he recognized the potential of Ultrasonic Metering: Making Ultrasonic Flow Metering technology accessible, compact and cost-effective.
The first serial projects contained Ultrasonic Flow Meters for the Heating Industry, especially for Gas-Boilers. Other projects followed, adding to the complexity of the Flow Meters with temperature, pressure and energy metering into one compact unit, used in all kinds of heating appliances as well as Heat Pumps. In parallel, companies from industrial backgrounds such as Production, Marine, Plastic Injection domains became interested in Allengra's technology. The firm started covering these industries with highly robust flow meters for heavy duty applications.
2015 was another breakthrough year for Allengra: For the first time, the company started a project for so-called SmartValves, a term coined by us referring to a valve-flowmeter combination, which regulates flow directly in one unit either by the flow, temperature or pressure measurement. The valve contains not a ball valve, but a ceramic disk valve, which in this form has never been introduced into the market before.
The same year marked the entry into the Food industry, with Allengra producing ultra-compact flowmeters specialized for coffee machine operations.
2020 marked the way into high-performance flowmeters, targeting high precision with better than 0.1% accuracy of measured value. This flow metering technology quickly made its way into applications requiring high performance such as Motorsports, Aviation and industrial dosing applications. In 2023, Allengra was selected as the sole supplier for the World Superbike Fuel Flowmeters. This was followed the year after with the selection as sole supplier of the Fuel Flowmeters and the Calibration of the Fuel Flow Meters for the Formula 1 Seasons 2026 to 2030.
Currently the company employs 70 people working in its offices in Romania and Germany. The high engineering and development focus of Allengra has made it the go-to company for Ultrasonic Flow Metering Solutions worldwide.
Specialising in ultrasonic flow measurement and precision sensing technology, we are full-service providers of flow metering and fluid analysis solutions across a wide range of industries
Allengra was founded with a focus on innovation and precision, and we have embedded this pioneering spirit into every project we undertake. Over the years, we've implemented our technology in complex industrial systems worldwide, consistently delivering accurate, actionable flow data.
Following each project, we provide comprehensive, easy-to-understand reports that answer your key operational questions. You don't need an engineering degree to interpret our findings — we distill complex measurements into clear, practical insights.
Our team is experienced in all aspects of ultrasonic flow measurement. Whether integrating your existing piping, using our portable clamp-on sensors, or deploying permanent installations, we can deliver solutions from sub-percent accuracy flow data for demanding industrial systems to quick-read datasets for routine monitoring.
In urgent situations, we can guide your team to collect reliable data with available equipment, and in some cases, we can even leverage legacy measurement data to assess past performance and system trends.
