1. A fluid level sensor assembly comprising:
a wye fitting having a main branch defining a fluid path for a fluid to flow from an inlet end to an outlet end arranged to be connected to an inlet of a valve, and a second branch opening from the main branch at a position intermediate the inlet end and the outlet end;
a level sensor is located in the second branch to detect a level of fluid in the second branch and to generate a command signal for operation of the valve according to the level detected; and
a nozzle defining a channel outside the main branch, the channel having a first opening into the main branch, at a position intermediate the inlet end and the second branch, and a second opening into the second branch, the second opening being smaller than the first opening.
