ABSTRACT:
A radar level gauge using microwaves for measuring a level of a surface of a product in a container, comprising a microwave unit, processing circuitry connected to said microwave unit, an interface for connecting said radar level gauge externally thereof, and a power management circuitry arranged to provide operating power to said microwave unit and said processing circuitry. The power management circuitry includes a temporary energy store, means for providing said temporary energy store with an intermediate voltage lower than an operating voltage required by said processing circuitry, in order to charge said energy store, and converting means, for converting an output voltage from said temporary energy store up to said operating voltage. According to this design, a sufficient amount of energy can be stored in the temporary energy store, operating at an intermediate voltage lower than the operating voltage of the radar level gauge. This output from the temporary energy store is then converted up to the required operating voltage. An advantage is that the intermediate voltage can be chosen so that the first temporary energy store can store a sufficient amount of power, without violating IS requirements.
