PROBLEM TO BE SOLVED: To provide a measuring device having high responsiveness, capable of instantaneously switching to a measurement method, in response to the presence of pulsation by instantaneously determining the presence of pulsation.TAKEMURA KOICHI竹村 晃一SHIBA BUNICHI芝 文一...
A fluid flow measuring device having a positive displacement piston in a precise bore glass flowtube, with flexible diaphragms at opposite ends of the flowtube, to seal the flowtube from the ambient environment. The flowtube is filled with a pure fluid or gas for uncontaminated operation of th...
This is in contrast to most conventional flow measuring devices, which have more sluggish response. This makes it possible to perform measurements related to transient conditions and to investigate turbulent flow characteristics. The main disadvantage of laser Doppler velocimetry is the necessity of ...

The flow measuring device (1) comprises: - a flow tube (2) with an inlet (4) and an outlet (6), the inlet (4) being designed to guide the fluid (F) into the flow tube and the outlet ( 6) is set up to lead the fluid (F) out of the flow tube (2), the flow tube (2)...
Use of a fluid flow measuring device as a microphone for detecting acoustic waves, said fluid flow measuring device comprising at least one heating element (H), at least a first temperature sensor (S1) arranged at a first predetermined spacing (r1) from the heating element (H), for generatio...
The measuring device uses a plate-shaped sensor element (2), supported in an opening in a carrier via an adhesive, with a measuring resistance in the path of the flow medium coupled to an electrical evaluation circuit (11). At least part of the sensor element and the evaluation circuit are...
