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.
