Firefighting monitor
First Claim
Patent Images
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 configured to determine an amount of force exerted by the firefighting fluid onto the body in at least one direction based upon a rotational orientation of the body as measured by said rotation sensor and the rate of flow of the firefighting fluid as determined by said flow rate detector, compare the amount of force to a threshold to determine if the amount of force has exceeded the threshold, and take a corrective action if the amount of force has exceeded the threshold, wherein the corrective action taken by said controller comprises at least one of;
moving a mobile boom to which said monitor is coupled;
adjusting an orientation of said monitor;
adjusting the flow rate of fluid flowing through said monitor; and
providing a warning that the amount of force has exceeded the threshold.

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.

22. 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 configured 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, compare the amount of force to a threshold to determine if the amount of force has exceeded the threshold, and take a corrective action if the amount of force has exceeded the threshold; the controller is programmed to allow a discharge of the firefighting liquid from the outlet at a first discharge rate when the rotation sensor is in a first rotational range; and the controller is programmed to automatically reduce the discharge of the firefighting liquid from the outlet to a second discharge rate less than the first discharge rate when the rotation sensor is in a second rotational range outside the first rotational range. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
