Bopp & Reuther 涡轮流量计
Measurement of liquids and liquefied gases in the chemical and petrochemical industry, petroleum industry, particularly at high operating pressures, high operating temperatures and low viscosities.
The turbine meter is an indirect volume meter. It essentially consists of a freely rotating axial turbine wheel in a liquid flow. The turbine wheel is rotated by the liquid and spins at a rotational speed, which corresponds to the average flow velocity of the liquid in the free cross section of the turbine flow meter. The rotational speed of the turbine wheel is thus proportional to the volumetric flow and the number of revolutions is proportional to the volume, which flows through.
The rotational movement is transmitted through the casing wall in a noninteracting manner to the outside by means of magnetic-inductive pulse pick up. A pick up mounted outside of the casing is used for this purpose. An electromagnetic field is generated with a coil located in the scanning head.
Application
The turbine meter is used for flow and volume measurement of liquid media such as:
• crude oils
• mineral oils
• acids
• alkaline solutions
• solvents
• water
• liquefied gases
RQ series turbine flow meters are built with nominal size of 10 to 300 mm. Depending on the nominal size, they can be employed from PN 6 to PN 320. The maximum allowable operating temperature of the material being measured can, depending on the model, reach 250°C.betragen.
Advantages
• proven, reliable measurement system
• approved by local bureau of standards
• high measuring accuracy
• high reproducibility
• harge flows
• inductive pulse pick up
• can be used for high operating overpressures, high operating temperatures and low viscosities
