cast iron positive displacement rorary vane flow meter
cast iron positive displacement rorary vane flow meter
LBTC positive displacement rotary vane flow meter belongs to positive displacement meter and is one of the most accurate measuring meters for measuring liquid of modern industry. The flow meter has stable performance and is insensitive to flow state change of upstream medium and change of medium viscosity. It has high measuring accuracy，good applicability and long life. Now it has widely used for every field such as process control of modern industry and trade settlement, etc.

Main features
◆The meter can be equipped with mechanical integrating instrument to realize local indication, and can be equipped with pulse signal transmitter or intelligent instrument to realize signal remote transmission;
◆High precision, the highest accuracy class is 0.2;
◆Rotary vanes are wear-resistant, and the vanes can operate in high pressure condition.
◆The pressure loss is small. Attenuation of accuracy is low and the pressure loss is no more than 0.1Mpa. (Such as nominal diameter is DN80)
◆The structure of the single housing is simple and the weight is light, The structure of double housing can not be influenced by thermal expansion and pressure, and deformation is very small.
◆Installation for the meter is very convenient , no need for auxiliary equipment such as straight pipe section, rectifier, etc. The meter cannot be influenced by pipe pieces such as valves, elbow, etc.
◆The meter can work very stable with no vibration and noise.
◆the pressure drop is more than velocity-type flow meter, but is better than other positive displacement meter.
