Product Description
Gas turbine flowmeters are mainly used for the flow measurement of natural gas, air, nitrogen and other medium fluids in industrial pipelines, and are hardly affected by parameters such as fluid density, pressure, temperature, and viscosity when measuring the volume flow of the working condition. High reliability, low maintenance, and can work within the operating temperature range of -10°C to +100°C.
Features
- High accuracy: the accuracy level is 1.0%-1.5%;
- Good repeatability: generally up to 0.05% ~0.2%, due to its good repeatability, it can achieve
extremely high accuracy after calibration or online calibration, so it is one of the preferred flow meters in trade settlement ;
Wide range: medium and large diameters can generally reach more than 20:1, small diameters are 10:1, and the starting flow is also low;
Small pressure loss: generally 0.1~2.5kPa under normal pressure;
The structure is compact, the volume is light, the installation and use are more convenient, and the circulation capacity is large;
Various display methods can be used, and lithium battery can be used for long-term power supply, which is convenient to use;
Adopt pulse frequency signal output, suitable for total measurement and connection with computer, no zero drift, strong anti-interference ability.
