Abstract

The invention discloses a flow monitoring system and a flow monitoring method, and relates to the technical field of flow monitoring. The flow monitoring system includes a liquid inlet, a liquid outlet, a first range flow meter and a second range flow meter. At least two branch flow paths are arranged between the liquid inlet and the liquid outlet; the range of the first range flowmeter is greater than that of the second range flowmeter; the first range flowmeter is arranged on the confluent flow path of at least two branch flow paths , the second range flowmeter is set on one of the branch flow paths, when the liquid flow rate is within the range range of the second range flowmeter, the liquid only passes through the branch flow path where the second range flowmeter is located; when the liquid flow rate is greater than the second range flowmeter When the range of the flowmeter is within the range, the liquid is diverted through at least two branch flow paths and then returned to the confluence flow path. The flow monitoring system can monitor the whole process of the continuous change of the liquid flow from small to large, which is beneficial to the flow characteristic test of valve products.

Description

technical field [0001] The invention relates to the technical field of flow monitoring, in particular to a flow monitoring system and a flow monitoring method. Background technique [0002] During the operation of the hydraulic system, it is often necessary to monitor the continuous change process of the flow from small to large. For example, in the P / Q characteristic test of the relief valve, it is necessary to pay attention to the small flow range of the relief valve to evaluate its opening rate and closing rate. It is also necessary to pay attention to its large flow range to evaluate the pressure gain of the relief valve in the large flow section. Positive displacement flowmeters are widely used in the industry because of their high measurement stability and high measurement accuracy. However, large-scale positive displacement flowmeters often have too large a volume corresponding to a single flow pulse signal, and their small flow sections often have monitoring blind sp...
