RV-LUGC vortex-street flowmeter for edible oil(clamp-on type)
1) Category and applications
Based on the measurement theory of flow meter, Rixin Flow Meter Ltd. Has developed a series of novel pressure influence mode flow meters which utilize the modern sensor and computer technology. portability and reliability, they have been widely used in many fields of petroleum, chemical industry, energy, foodstuff, environment protection, water conservancy and so on.
2)Basic technical performance

The meter installs a condition request:
The Wo street flow meter visits to keep a tube segment to contain certain request to the top and bottom that installs to click, otherwise effects dielectric's streaming field in the piping and effects the measurement accuracy of meter.The top and bottom of meter visits to keep a tube segment length to request to see chart(three)
