Installation Requirements
Unidirectional operation: (fluid flows in one direction)
- Without rectifier, along the fluid direction, the length of the front straight pipe should be >10DN and the length of the rear straight pipe should be >3DN.
- With rectifier, along the fluid direction, the length of the front straight pipe should be >5DN and the length of the rear straight pipe should be >3DN.

Bi-directional operation: (fluid flow in both directions)
- Without rectifier, length of front straight pipe should be ≥10DN, length of rear straight pipe should be >10DN.
- With rectifier, the length of the front straight pipe should be >5DN and the length of the rear straight pipe should be >5DN.

Typical Feature Curves

Typical characteristic curves of flow meters are shown in the figure, with the Y-coordinate representing the basic error of the flow meter and the X-coordinate representing the percentage of maximum flow rate.
Application

Tips: How to read ultrasonic gas flow meter?
Ultrasonic gas flow meter related measurement parameters are displayed on the liquid crystal screen of the meter, which can be read directly.Gas flow meter's head adopts special connection structure, when the meter is restricted by the installation environment, which affects the normal reading, the head can be rotated at an arbitrary angle of 0~350° to facilitate the reading.
When the flow meter works in “0” zone, the power transformer supplying power to the safety grid should meet the requirements. It is not allowed to replace the components or structure, so as not to affect the explosion-proof performance.
