Beschreibung
Zusammenfassung:	The utility model provides a high-precision wide-range integrated differential pressure type flow measuring device. The device comprises an integrated throttling device, a pressure detection device, atemperature detection device, a high-range flow measurement device, a low-range flow measurement device and a flow totalizer, the integrated throttling device comprises a throttling device body, a pressure guide device and a pipeline body which are integrally formed and designed. The flow totalizer is in communication connection with the pressure detection device, the temperature detection device, the high-range flow measurement device and the low-range flow measurement device. The flow totalizer can automatically switch the flow value measured by the high-range flow measuring device and theflow value measured by the low-range flow measuring device according to the actually measured flow value, and performs compensation calculation and display on the switched flow values. The device hasthe advantages of being hig
