10. An ozone administering and measuring unit comprising:
an input line having an upstream end adapted to be in fluid communication with a body of water to be treated, and a downstream end adapted to be in fluid communication with the body of water;
an ozone injector which is connectable to an ozone gas generation system;
a branching line in fluid communication with the input line and the ozone injector;
an ozone supply line in fluid communication with the ozone injector;
a bypass control valve in fluid communication with the ozone supply line and the water input line, the bypass control valve having an open position and a closed position, wherein water is prevented from flowing from the ozone supply line through the bypass control valve and into the input line when the bypass control valve is in the closed position; and
a pressure differential measuring device adapted to measure a pressure differential between a first location upstream relative to the bypass control valve, and a second location downstream relative to the bypass control valve.
