Thermal, flow measuring device and arrangement with a tube or pipe and the thermal, flow measuring device
First Claim
1. A thermal, flow measuring device, comprising:
- a metal sensor housing having a hollow body and a longitudinal axis, the hollow body having a base, wherein the hollow body is embodied to connect to a plug-in apparatus and/or to a tube or pipe wall;
a first pin sleeve and a second pin sleeve disposed within the sensor housing and protruding from the base, wherein the first pin sleeve and the second pin sleeve define a connecting axis and a midpoint between the two pin sleeves;
a first heater disposed within the first pin sleeve and a temperature sensor disposed within the second pin sleeve, wherein the temperature sensor is embodied to ascertain a temperature of a medium; and
at least two elongated elements disposed within the sensor housing and extending from the hollow body in parallel with the two pin sleeves, wherein the at least two elongated elements have at least the same length as the two pin sleeves,wherein on a cutting plane perpendicular to the sensor housing longitudinal axis another axis extends that is perpendicular to the connecting axis, wherein the separation of the elongated elements in their course parallel with the axis lessens at least in certain regions, and wherein the sensor housing has two mirror symmetric planes that are perpendicular to one another and perpendicular to the cutting plane.

Abstract
The application discloses a thermal, flow measuring device comprising: a sensor including a metal sensor housing having a hollow body and a base; and at least first and second pin sleeves protruding from the base. In a first of the two pin sleeves a first heater is provided and in a second of the two pin sleeves a temperature sensor is provided for ascertaining a temperature of a medium. At least two elongated elements extend with at least the same length as the pin sleeves starting from the hollow body in parallel with the two pin sleeves. On a cutting plane perpendicular to the sensor axis another axis extends that is perpendicular to the connecting axis and wherein the separation of the elongated elements in their course parallel with the axis lessens in certain regions.
