These devices are available as accessories and are easily installed in the mounting position foreseen. A vertical and a horizontal measuring station are provided on the test stand. The flowmeters are supplied with water by the test stand. As the test stand has a closed water circuit with supply tank and pump, only a mains electricity supply is required to operate the test stand.

To be able to check the function and precision of the flowmeters under investigation, a reference flowmeter is provided.
