FIREFIGHTING MONITOR
First Claim
1. A firefighting monitor comprising:
- a body having an inlet for receiving firefighting fluid and an outlet for discharging the firefighting fluid, said body including a tubular section rotatable about an axis;
a rotation sensor for measuring an amount of rotation of said tubular section about said axis;
a flow rate detector for determining a rate of flow of the firefighting fluid through the body from the inlet to the outlet; and
a controller in communication with said rotation sensor and said flow rate detector, said controller adapted to determine an amount of force exerted by the firefighting fluid onto the body in at least one direction based upon information from said rotation sensor and said flow rate detector.

Abstract
A firefighting monitor includes logic circuitry for determining the reaction force caused by the flow of firefighting fluid therethrough. The reaction force may be communicated to structures remote from the monitor for taking appropriate actions in response to the reaction forces exceeding one or more criteria. The monitor may also use flow and nozzle data for calculating a reach of the stream of the fluid, and may transmit this reach data to a remote location. The monitor may also utilize multiple pressure sensor transducers positioned inside the monitor for determining the rate of fluid flow, rather than a paddle wheel-type sensor.

15. A firefighting monitor comprising:
-
a base having an inlet for receiving firefighting fluid; a first section rotatably coupled to said base and rotatable about a first axis; a second section rotatably coupled to said first section and rotatable about a second axis, said second axis having a different orientation than said first axis, said second section adapted to selectively couple to a nozzle through which the firefighting fluid may be discharged; a first pressure sensor adapted to detect a pressure of the firefighting fluid within said monitor at a first location; a second pressure sensor adapted to detect a pressure of the firefighting fluid within said monitor at a second location different from said first location; and a controller in communication with said first and second pressure sensors, said controller adapted to determine a flow rate of firefighting fluid flowing through said monitor based upon a difference between pressures detected by said first and second pressure sensors. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of controlling a firefighting monitor comprising:
-
providing a monitor coupled to a structure, said monitor including a plurality of sections rotatable with respect to each other; determining a flow rate of firefighting fluid flowing through said monitor; determining an amount of force exerted by the flowing firefighting fluid on the monitor in at least one direction; and determining if the amount of force meets a criterion and, if the amount of force does meet the criterion, doing at least one of the following; rotating at least one of the sections of the monitor until said amount of force no longer meets the criterion; reducing the flow of firefighting fluid through said monitor until said amount of force no longer meets the criterion; moving said structure until said amount of force no longer meets the criterion; and providing a warning to a user of the firefighting monitor that said criterion has been met. - View Dependent Claims (23, 24, 25)
