1. A spacer for a sensor of a thermal flow measuring device, having:
- hold-down means;
a first cavity for accommodating a resistance thermometer;
at least a first planar area which faces said first; and
a second cavity, through which the resistance thermometer can be pressed by means of said hold-down onto said first planar area.

7. A thermal flow measuring device for determining and/or monitoring flow of a measured medium through a measuring tube, having:
-
a first sensor; and a second sensor, said first sensor has a first housing secured in a sensor holder and a first resistance thermometer, and said second sensor has a second housing secured in the sensor holder and a second resistance thermometer, wherein; at least said first resistance thermometer is embodied in such a manner that it can be heated; said first resistance thermometer is at least partially inserted into a first cavity of a first spacer in said first housing, and said second resistance thermometer is at least partially inserted into a first cavity of a second spacer in said second housing; and the first spacer and the second spacer have; hold-down means; a first cavity for accommodating a resistance thermometer; at least a first planar area which faces said first; and a second cavity, through which the resistance thermometer can be pressed by means of said hold-down onto said first planar area. - View Dependent Claims (8, 9, 10)

11. A method for manufacture of a sensor of a thermal flow measuring device, comprising the steps of:
-
a thin-film resistance thermometer, which has a first surface and a second surface, which lies opposite the first surface, is at least partially inserted into the first cavity of a spacer; is soldered with its first surface onto the first planar area of the spacer; and at least during the soldering, a hold-down is led through the second cavity of the spacer for pressing the thin-film resistance thermometer onto the first planar area of the spacer. - View Dependent Claims (12, 13, 14, 15)
