Description
TECHNICAL FIELD
[0001] The utility model belongs to flowmeter technical field, concretely relates to a liquid vortex street type flowmeter. BACKGROUND
[0002] The liquid vortex street type flowmeter is a flowmeter based on the Karman vortex principle to measure the volume flow of liquid, steam or liquid, the volume flow or mass flow under standard conditions. When the fluid flows through the non-streamlined object (such as triangular column vortex generator) placed in the pipeline, two rows of alternating vortices will be generated downstream of the object, and the release frequency of these vortices is proportional to the flow rate of the fluid. By measuring the frequency of the vortex, the flow rate of the fluid can be calculated, and then the flow of the fluid can be calculated.
[0003] The vortex flowmeter is widely used in industrial production, energy measurement, environmental protection, transportation and other fields, and is suitable for measuring the following fluids: gas (such as air, nitrogen, natural gas, etc.), liquid (such as water, oil, etc.), steam (such as saturated steam and superheated steam).
[0004] But relying solely on the vortex probe to detect liquid flow may not guarantee the accuracy of the measurement. INVENTION CONTENTS
