Abstract: A level sensor (10) for use in a process application measures height (L) of a product (14) in a tank (12). The level meter (10) includes a microwave feedhorn (18) directed into the tank (12), an electronics housing (16) spaced apart from the feedhorn (18) and a microwave waveguide (20) extending therebetween. A microwave transducer (50) in the housing (16) couples to the waveguide (20) and sends and receives microwave signals. A microprocessor (30) in the housing (16) identifies echoes from the microwave signals which are generated and sensed by the microwave transducer (50). The microprocessor (30) determines height (L) of the product (14) based upon a microwave echo from the product (14) and a microwave echo from the feedhorn (18). The microprocessor (30) compensates for the effect of propagation delay through the waveguide (20) on height measurements with the feedhorn echo and provides (18). The microprocessor (30) compensates for the effect of propagation delay through the waveguide (20) on height measurements with the feedhorn echo and provides an output related to height (L) of the product (14) in the tank (12).
