Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump, valve and flow meter integrated pump. Background Art

[0002] In some precision liquid supply systems, a water pump is often used in conjunction with a valve flowmeter. The water pump provides power to the process system, and the flowmeter calculates the flow rate of the liquid supply system. Existing pump-valve flowmeters typically consist of a water pump and a flowmeter connected to the pump's outlet. A connecting pipe connects the pump's outlet and the flowmeter. After being pumped out of the pump, water passes through a section of pipe. This can easily cause unstable water pressure due to piping, widening the flowmeter's monitoring range and making it difficult to ensure accurate measurement data. Utility Model Content
