Upon reaching the product surface, the microwave pulses arereflected. The running time is evaluated by the instrument and output-ted as level.High frequency microwave impulses are guided along a steel cableor rod. When reaching the product surface, a part of the microwaveimpulses is reflected. The other part passes the upper product and isreflected a second time by the interface. The running times to the twoproduct layers are processed by the instrument.VersionsScope of deliveryApplication areaFunctional principle -level measurementFunctional principle - in-terface measurement
