Description
Overview
GAOTek air flow meter is a kind of velocity flowmeter, which is designed based on Karman vortex principle. It is mainly used for flow measurement of medium and fluid in industrial pipelines, such as flow control and measurement of gas, steam or liquid and other media.
Features
- Higher accuracy and stronger anti-interference ability
- More earthquake resistant and long life
- It has an HD digital display
- Has a sensitive interface response
- A good LCD screen circuit board
- Ensure no pressure when working at –25 °C to70 °C
- Low pressure loss and environmental protection
