Abstract: An apparatus for monitoring at least one physical or chemical process variable, comprising at least one measurement branch and a compensation branch connected in parallel therewith for compensating the influence of at least one environmental parameter on the process variable and/or on the measuring of the process variable. The measurement branch includes at least one primary sensor unit and a primary electronics unit for signal registration, evaluation, and/or feeding. The compensation branch includes at least a secondary sensor unit and a secondary electronics unit. The secondary sensor unit is so embodied that it registers a physical or chemical variable characteristic for the at least one environmental parameter, wherein the secondary electronics unit is so embodied that it draws the required energy from the measurement branch, and that it produces from the characteristic physical or chemical variable a compensation signal, which it transmits to the primary electronics unit of the measuring branch.

Abstract: A clamp-on ultrasonic flowmeter includes a measuring tube, a pair of ultrasonic contact transducers, and an electronic measuring/operating circuit for operating the transducers. Each transducer includes a transducer element for generating and detecting ultrasonic signals and a coupling element. The transducer element is located on one side of the coupling element facing away from the measuring tube, and is designed to be acoustically coupled to the measuring tube via another side of the coupling element facing the measuring tube, and designed to transmit ultrasonic signals between the transducer element and measuring tube. The ultrasonic flowmeter comprises an adjusting device for at least one transducer for adjusting the transducer. The adjusting device is arranged and configured to modify at least one angle of the signal path with respect to the coupling face or a signal path length, wherein the adjusting device has at least two degrees of freedom.
