Vortex Flowmeter

The vortex flowmeter is based on the Karman vortex theory and uses piezoelectric crystals to detect the vortex frequency generated when the fluid passes through the triangular column in the pipeline, thereby measuring the flow rate of the fluid. Vortex flowmeter is widely used in petroleum, chemical, power heating, and other industries.

Advantages:

• The product has high reliability, long-term stability, simple structure, and easy maintenance;
• The zero point has no drift, and the performance is very stable.
• Various structural forms, including pipeline type, plug-in flow sensor, and other forms;
• Small pressure loss, high accuracy,
• Flexible installation
• The circuit adopts a variety of protection modes, which is anti-surge and has strong adaptability;
• 316L stainless steel sensor housing
• Long-life lithium battery
• High and low-temperature adaptability
• The measurement range is wide, and the range ratio can reach 1:10~1:25.
