Apparatus for flow measurement in compressed air installations and flow measuring device for this

摘要

The invention relates to an apparatus for flow measurement in compressed air installations having - at least one flow measuring device (100.1, ..., 100.n), - at least one compressed air outlet (25.1, ..., 25.n), and - one compressed air supply (26.1, 26.2). To measure the flow, the compressed air is led to two compressed air inlets (26.1) of a compressed air supply designed as a compressed air distributor (26) and distributed at equal pressure via its compressed air outlets (26.2.1, ..., 26.2.n) to connection inputs (16) of the flow measuring devices (100.1, ..., 100.n). After the measurement of its flow velocity in the flow measuring devices (100.1, ..., 100.n), the compressed air is present at the compressed air outlets (25.1, ..., 25.n) connected to their connection outputs (17). The flow measuring devices (100.1, ..., 100.n) are connected, via a bus system (BUS), to a supervision unit (ÜE), via which the measurement results of the flow measuring devices (100.1, ..., 100.n) may be transmitted. The measurement results of the flow measuring devices (100.1, ..., 100.n) can be interrogated by a supervising computer using an allotted address. <IMAGE>
