Abstract
Flow measuring device for ascertaining flow of a measured medium flowing through a measuring tube, which flow measuring device has a first housing for protruding into the measured medium, wherein the first housing has a first surface intended to face the measured medium, wherein the flow measuring device includes a second surface for bounding the measured medium, and wherein each separation between the first surface for bounding the first housing from measured medium, the second surface for bounding the measured medium and the first surface of the first housing amounts to at least 1 mm.
Claims9
An ultrasonic, flow measuring device for ascertaining the flow of a measured medium flowing through a measuring tube, which flow measuring device, comprises:
- an ultrasonic transducer;
- a first housing of said ultrasonic transducer which protrudes into the measured medium, said first housing has a first surface intended to face the measured medium;
- and
- a second housing, which has a second surface for limiting the volume of the measured medium, wherein:
- said first housing is connected with said second housing via a connecting element arranged between said first housing and said second housing;
- said first housing and said second housing are so arranged relative to one another that a separation between any two points of said first surface and said second surface amounts to at least 0.1 mm, and each separation of said first surface from said second surface measured perpendicular to said first surface amounts to at least 0.5 mm;
- and
- each separation of said first surface from said second surface measured perpendicular to said second surface amounts to at least 0.5 mm.
The use of an ultrasonic, flow measuring device for ascertaining the flow of a measured medium flowing through a measuring tube, which flow measuring device, comprises:
- an ultrasonic transducer;
- a first housing of said ultrasonic transducer which protrudes into the measured medium, said first housing has a first surface intended to face the measured medium;
- and a second housing, which has a second surface for limiting the volume of the measured medium, wherein:
- said first housing is connected with said second housing via a connecting element arranged between said first housing and said second housing;
- said first housing and said second housing are so arranged relative to one another that a separation between any two points of said first surface and said second surface amounts to at least 0.1 mm, and each separation of said first surface from said second surface measured perpendicular to said first surface amounts to at least 0.5 mm;
- and each separation of said first surface from said second surface measured perpendicular to said second surface amounts to at least 0.5 mm, wherein:
- the flow measuring device is applied in a process plant for ascertaining flow of an at least partially gaseous, measured medium, especially for ascertaining flow of biogas.
