EP Ehrler Prüftechnik Engineering

The company is specialist in the field of flow measurement technology for gases. They build test benches and measurement sections in the area of the complete calibration pyramid – from the working standard such as hydrogen-capable flow measurement systems for consumption measurement on fuel cells through to high-precision primary standards such as those used by the Physikalisch-Technische Bundesanstalt (PTB).

A current plant highlight is the construction of a test bench for humidifiers in fuel cell drives. The test bench provides an air mass flow of up to 1500kg/h and a humidification and dehumidification capacity of up to 150kg/h for testing. Due to a consumption-optimized design, the system is the unbeatable in terms of energy in comparison with the competition.

Especially the company is involved in various research projects. For the, the MetHyInfra project focuses on the flow measurement of hydrogen with critical nozzles and up to 1000bar. With this technology, the calibration of hydrogen filling stations may take place in the future.
