OVERVIEW
The FZSG and HZSG series averaging tube flow meters are a new type of flow measurement instrument developed and researched by our company, and have obtained national patent rights.
The averaging tube flowmeter is a porous self averaging flowmeter, also known as the flute tube, toba tube, annubar, power bar, Alibaba tube, etc. It is developed based on the pitot tube principle in fluid flow measurement.
Due to its many unique features, the averaging tube flowmeter can be widely used for accurate measurement of volume flow or mass flow of various liquids, gases, and vapors in industries such as petroleum, refining, natural gas, chemical, water treatment, and brewing.
FEATURES
- Integrated structure, good completeness
- No easily worn rotating parts, rarely repaired
- Small pressure loss, accounting for only 2-15% of the differential pressure, is its prominent feature
- The pressure difference can reach 30mmH2O
- The pipeline diameter has a wide range of adaptability, and when the diameter is larger, an insertion structure is used, which highlights its superiority
- Good accuracy and long-term operational stability, with an accuracy of ± 1% and a stability of ± 0.1%
- The uniform velocity tube flowmeter has low requirements for pipeline layout and can be directly installed downstream of a 90 ° elbow with only twice the pipe diameter, still achieving high accuracy
