Basic Info
Model No.: CX-VFM
Product Description
Model NO.: CX-VFM Main Application: Water, Wastewater, Diesel Fuel, Fuel Oil, Nature Gas, Corrosive Liquid/Gas Sensor: Tube/Flange Type: Vortex Flow Meter Measuring Principle: Mechanics Certification: CE, SGS, ISO Warranty: One Year Price: Competitive Trademark: GN Origin: Shanghai Accuracy: >±1% Size: DN50-100 Application: Environmental Protection Measuring Media: Liquid Measurement Object: Closed Pipeline (Mainland) Brand Name: Gn Exported: More 80 Countries Maintenance: Less and Easy Specification: CE SGS HS Code: 9026100000 vortex flow meter Working principle
To install a vortex generator(bluff body)in the fluid,which can produces regular vortex at both sides of the vortex generator altematively.Such vortex is called Karman Vortex.Vortex trains are asymmetrically arranged at the downstream of the vortex geberator. Suppose the generating frequency of the vortex is f,the average speed of the incoming flow of the tested medium is V,the head-on width of the vortex generator is d,and the diameter of the flowmeter is D,and base on the principles of Karman Vortex.
