It also supports micro-flow measurement in small-diameter pipelines. Its measurement accuracy is not affected by pressure or flow fluctuations, making it a reliable solution for industrial flow monitoring and quantitative control.
Why Choose This Round Gear Flow Meter?
Selecting the right flow meter is essential for maintaining process accuracy and long-term system reliability.
The NOIKE-AH Round Gear Flow Meter offers several practical advantages:
- Suitable for both standard and high-viscosity liquids
- High measurement accuracy and repeatability
- Supports pulse and analog output for industrial automation
- Wide measuring range with a rangeability of 1:100
- Resistant to high pressure, extreme temperatures, corrosion, and contaminated media
- Compact size with stable, low-noise operation
- Suitable for both continuous flow monitoring and quantitative control applications
Operating Principle
The Round Gear Flow Meter is a positive displacement flow transmitter designed to accurately measure the flow or instantaneous flow of liquids inside pipelines.
It is particularly suitable for measuring heavy oil and high-viscosity media such as resin and vinol. The meter can measure fluids with viscosities of up to 10,000 Pa·s. Its compact structure, light weight, low operating noise, and stable performance make it suitable for both industrial process control and micro-flow measurement in small-diameter pipelines.
Thanks to its low starting flow rate and wide rangeability, measurement accuracy remains stable and is not affected by pressure or flow variations.
