Abstract: The present disclosure relates to a thermal flowmeter comprising at least one measurement sensor having at least one sensor element for determining a measured value for determining the flow rate of a medium. A measurement transducer determines the flow rate using the determined measured value. A tubular connecting element connects the measurement sensor to the measurement transducer and a protective sleeve is provided, which is mechanically connected to the tubular connecting element. The protective sleeve has a sleeve casing having at least two openings, an inflow opening through which the medium can be delivered to the measurement sensor and an outflow opening through which the medium can flow out of the measurement sensor. The connection between the protective sleeve and the tubular connecting element is a connection which is positively engaged at least in part.

Abstract: A magnetic-inductive flow measuring device includes measuring electrodes, each having an end face including a planar annular edge region surrounding a center region, each annular edge region configured to seat against a sealing surface of an inner mold such that the center region of the end face does not contact the inner mold during the injection molding of a measuring tube body. A method for manufacturing the magnetic-inductive flow measuring device includes steps of providing and positioning an inner mold, an outer mold and two measuring electrodes, where each annular edge region of each measuring electrode seats against its corresponding sealing surface of the inner mold such that the center region of the measuring electrode protrudes into the corresponding recess of the inner mold without contacting the inner mold.
