Abstract
A level meter for measuring the fill level of a medium in a vessel, includes a reference container that can be connected to the vessel in a manner whereby the level in the reference container is identical to that in the vessel. The reference container is provided with an adapter unit for a microwave level meter operating by the radar principle which adapter unit encompasses an injection device for coupling-in a microwave signal. This constitutes a low-cost solution for connecting a microwave level meter to a reference container, ensuring optimized signal injection.
