Precession Vortex Flow Meter
Product Description
Precession vortex flow meter is a new type of gas flow meter that adopts micro-processing technology and has the advantages of strong function, wide flow range, simple operation and maintenance, and convenient installation and use. The main technical indicators have reached the level of similar foreign products.
Application
Applied in industrial production process, energy measurement, environmental protection engineering, transportation, biotechnology, scientific experiments, marine meteorology, rivers and lakes.
Features
- No mechanical moving parts, corrosion resistance, stable and reliable, long life, no special maintenance required for long-term operation;
- Realize electromechanical integration, and the daily measurement process does not need manual duty;
- The process installation conditions are not harsh, and the upstream and downstream straight pipe sections of the instrument can be greatly shortened compared with the orifice plate and the vortex flow meter;
- The measurement accuracy of the system can meet the current trade measurement requirements (≤1.5%);
- The flow measurement range is wide (qmax/qmin=15～20), which can work effectively in some small flow areas that the orifice plate and vortex flow meter cannot reach;
- Small size, light weight, convenient for off-line calibration.
- Only need to replace the battery(micro power consumption) and the parameters of the measured medium regularly.
