ABSTRACT:
A measuring head for an ultrasonic flowmeter, in which an ultrasonic coupling element and a measuring head housing are cast together and form, along with casting material, a contact surface E. The surface E allows an effective transfer of heat to the measuring head. In order to compensate manufacturing tolerances, the distance a between the measuring head housing and the ultrasonic coupling element is at least 1 mm in the area of the contact surface E.
