A block calibrator for calibrating a temperature sensor includes a calibrator sleeve having at least one sensor bore into which the temperature sensor is insertable along a longitudinal direction. The calibration sleeve also includes a body having at least two sections having different thermal conductivities.

Calibrator sleeve and block calibrator for calibration of a temperature sensor

The device is used to determine the flow rate of a medium, e.g. of a fluid or a gas, including a housing (,) with a chamber (,) through which the medium is axially flowing and which receives an impeller wheel (,) with one blade (,), whereas the impeller wheel (,) is provided with a carrier body (,) having a centrical boring (,) for receiving an axle (,), whereas the carrier body (,) is provided in the area of the axle (,) with at least one opening (,) running radially to the centrical boring in the carrier body (,), whereas the axle (,) is arranged in the carrier body (,) by at least one, preferably two radial bearings (,), whereas a radial allowance is provided between the boring of the carrier body (,) and the axle (,), whereas, due to the radial allowance between boring (,) in the carrier body (,) and axle (,), water is entering at the open side of the boring (,) and is exiting through the radially running opening (,) in the carrier body (,).
