Abstract:
1. A mixer nozzle assembly for mixing fluid introduced into a tank having a tank volume therein, the mixer nozzle assembly comprising: a stationary body comprising at least one inlet and at least one outlet in fluid communication with each other; a rotatable body mounted on the stationary body for rotation about an axis in a predetermined direction, the rotatable body comprising at least one intake aperture and at least one outlet aperture in fluid communication with each other, said at least one intake aperture being in fluid communication with said at least one outlet of the stationary body for permitting the fluid to flow from said at least one inlet of the stationary body to said at least one outlet aperture, to exit therefrom into the tank volume; said at least one outlet aperture being formed to direct the fluid exiting the rotatable body therethrough in a direction non-aligned with the axis, for causing the rotatable body to rotate in the predetermined direction about the axis; the fluid exiting said at least one outlet aperture mixing with at least a part of the fluid in the tank volume; a governor subassembly for controlling a speed of rotation of the rotatable body in the predetermined direction about the axis, the governor subassembly comprising: a hydraulic circuit for governing a flow rate of the hydraulic fluid to adjust the flow rate to the preselected flow rate, for adjusting the speed of rotation of the rotatable body to the preselected speed; a speed indicator for indicating the speed of rotation of the rotatable body about the axis relative to the stationary body, the speed indicator comprising:
