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) SPECIAL EXECUTIONS ON REQUEST - Bosses with NPT conical threads. - Axis and rotor propeller in blue colour. * Registered trademark by DuPont Dow Elastomers.
