Monitoring of fluids

Claim 1

Apparatus for monitoring a first set of parameters of that water contained in a body of recreational water subject to having a second set of parameters directly controlled by water controlling mechanisms comprising a first station incorporating a plurality of sensors each of which is adapted to provide signals indicating values of at least one of said first set of parameters, receipt circuit means adapted to receive signals from the sensors, a first radio transmitter circuit fed from the receipt circuit means; a second station separable from the first station and the water controlling mechanisms, and incorporating a radio receiving circuit for receiving signals from the first radio transmitter circuit and separating signals form the first radio transmitter circuit due to each of the sensors, an output means providing visual and/or audio outputs based on the separated signals as received therein, control circuits selectively providing control signals based on the separated signals as received in the output means indicating the manner in which the water controlling mechanisms are to be operated, and a second radio transmitter circuit adapted to receive the control signals from one or more of the control circuits and transmit command signals based thereon; and at least one controller radio receiving circuit adapted for electrical connection to at least one of the water controlling mechanisms and for receiving the command signals, and further adapted to correspondingly operate that one of the water controlling mechanisms in controlling a corresponding one of said second set of parameters.

Claim 10

A method of monitoring conditions of a body of water by obtaining signals form sensors detecting a plurality of conditions; amplifying and encoding such signals and transmitting them via a radio transmitter to a remote receiver; decoding and separating the signals with respect to the separate sensors at the receiver and converting the same into signal voltages; passing such signal voltages to a visual and/or audio output; and transmitting by radio command, signals to operate remote water controlling mechanisms in dependence on the visual and/or audio output.

Claim 11

A method of monitoring conditions of a body of water by obtaining signals form sensors detecting a plurality of conditions; amplifying and encoding such signals and transmitting them via a radio transmitter to a remote receiver; decoding and separating the signals with respect to the separate sensors at the receiver and converting the same into signal voltages; passing such signal voltages to a visual and/or audio output; and transmitting by radio command, signals to operate remote water controlling mechanisms in dependence on the visual and/or audio output.
