General information
Features and applications
The indicator can be mounted in any position.
In case of mounting on rigid tubes, it is recommended to place the indicator perfectly aligned with the tubes.
The indicator operates with two-way liquid flows.
For rotating the propeller it is required a minimum fluid flow rate (Q**) depending on the type of fluid and its viscosity (shown in cSt, see table)
Other executions
Special executions on request
- Bosses with NPT conical threads.
- Axis and rotor propeller in blue colour.
