- AOLU vortex flowmeter
Measurement principle
The product uses the Karman vortex street principle for measurement. When the fluid passes through the throttling device (such as the triangular metal cylinder in the vortex street), vortices will be generated alternately in the downstream direction. The number of vortices is proportional to the flow rate of the fluid. The pressure change generated by the vortex can be sensed by the sensor, forming an electrical pulse, thereby obtaining the flow rate data.
Main features
Good versatility, can measure the flow rate of liquid and gas;
No moving parts, high reliability;
The main body and vortex generator structure are made of stainless steel, long service life;
The flow parameters are not affected by the measured pressure, temperature, density, viscosity and its components;
High accuracy and good repeatability;
Wide measurement range, up to 1:15;
Small pressure loss, low operating cost, more energy-saving;
The output signal is linearly related to the flow, with pulse and standard current optional;
The dual piezoelectric crystal sensor is more durable;
The vortex street dedicated filtering technology can effectively remove the interference caused by pressure fluctuations and pipeline vibration;
Stable backlight display makes reading easier;
Won: CCRI17.1324 explosion-proof certificate CMA;
Won: Fujian Quality and Technical Supervision Bureau "Measuring Instrument Type Approval Certificate" CPA Minliangji No. 1000.
Application scenarios
Applicable to the flow rate and flow measurement of steam, various gases, organic solvents, liquids (especially non-conductive and low-conductive) in industrial sites.
