The remote transmission turbine flowmeter can be connected to the control system or used in conjunction with a secondary display instrument. It is suitable for measuring media (clean media) in closed pipes that are not corrosive to stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and hard alloys, and are free of impurities such as fibers and particles. If it is matched with a display instrument with special functions, it can also perform quantitative control and over-quantity alarms. The explosion-proof type of this product can be used in environments with explosion hazards. Our turbine is suitable for media with a viscosity of less than 5×10-6m2/s at working temperature. For liquids with a viscosity greater than 5×10-6m2/s, the flowmeter must be calibrated with real liquid before use.
1. Good accuracy: The flow meter is a carbide bearing thrust type with good accuracy and improved wear resistance
2. Compact structure: The structure is compact and lightweight, easy to install and maintain
3. Simple structure: The structure is simple, firm and easy to disassemble
4. High accuracy: High accuracy, generally up to ±0.5%R, ±1.0%R with good repeatability
5. Short-term repeatability: Up to 0.05% - 0.2%
6. Pressure resistance: High pressure resistance, small pressure loss, strong flow capacity and strong anti-vibration performance
