Title:
流体の貫流過程を測定するための、２つの側において流入可能な装置
Document Type and Number:
Japanese Patent JP6526912
Kind Code:
B2
Abstract:
A device for measuring flow processes of fluids includes an inlet, an outlet, a housing in which is arranged a drivable positive displacement flow meter which includes a positive displacement chamber in which a driven impeller is rotatably arranged, a first supply duct connecting the displacement chamber with the inlet, a first discharge duct connecting the displacement chamber with the outlet, a first inlet port, a second supply duct connected to the inlet, a displacement flow meter bypass with a differential pressure sensor, and an evaluation and control unit which controls the displacement flow meter based on a differential pressure applied to the pressure sensor. Cavitation wear of the positive displacement meter is reduced by the first supply duct opening into a front of the displacement chamber via the first inlet port, and the second supply duct opening into a rear of the displacement chamber via a second inlet port.
