Abstract
Official abstract text for this publication.
The present invention discloses an ultrasonic flow meter comprising a generator circuit and a receiver circuit electrically separated from the generator circuit. The flow meter further comprises transducer switching means for controlled connection of ultrasonic transducers to either the generator circuit or to the receiver circuit. The output impedance of the generator circuit and the input impedance of the receiver circuit are controlled to be substantially zero.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ultrasonic flow meter arranged to measure a flow rate of a fluid, wherein the ultrasonic flow meter comprises: at least two ultrasonic transducers arranged for transmission and receipt of ultrasonic signals in opposite directions across a measuring distance, wherein the at least two ultrasonic transducers comprise at least a first transducer positioned at one end of the measuring distance and at least a second ultrasonic transducer positioned at the…
