Abstract
Abstract Atmospheric emissions from multiple sources are monitored by measuring at each source certain values of these emissions which are parametrically related to those emission characteristics which it is desired to monitor. These measured values are then transmitted to a central station where they are transformed into indications of said characteristics to be monitored.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
A system for monitoring a predetermined parameter of the atmospheric emissions flowing through a stack from a source of such emissions, comprising: means for measuring in said stack the values of several parameters of said emissions different from each other and also different from said predetermined parameter; means for transmitting said measured values to a location remote from said source; and means for processing said transmitted values at said remote location to derive therefrom the desired monitoring information represented by said predetermined parameter; said means for transmitting operating under the control of said remote location.
Claim 2
Independent Claim
95 words
A system for monitoring a predetermined parameter of the atmospheric emissions flowing through a stack from a source of such emissions, comprising: means for measuring in said stack the values of several parameters of said emissions different from each other and also different from said predetermined parameter; means for transmitting said measured values to a location remote from said source; and means for processing said transmitted values at said remote location to derive therefrom the desired monitoring information represented by said predetermined parameter; said means for transmitting operating under the control of said remote location.
Claim 3
Dependent Claim
20 words
The system of claim 1 characterized in that said means for measuring operates under the control of said remote location.
Claim 4
Dependent Claim
30 words
The system of claim 1 characterized in that said predetermined parameter is the rate of said emissions and said measured parameters are different from but parametrically related to said rate.
Claim 5
Dependent Claim
42 words
The system of claim 1 further comprising means for measuring the values of said several emission parameters of emissions from a plurality of different emission sources, and wherein said processing means is effective to derive said predetermined parameters for all said emissions.
Claim 6
Dependent Claim
19 words
The system of claim 4 further comprising means for transmitting to said remote location all the said measured values.
Claim 7
Dependent Claim
29 words
The system of claim 4 further comprising means for transmitting the said values from said different sources to said remote location in sequence from different ones of said sources.
Claim 8
Dependent Claim
21 words
The system of claim 3 further comprising means for deriving from said transmitted values a quantity representative of said emission rate.
Claim 9
Dependent Claim
21 words
The system of claim 1 further comprising means for comparing at said remote location said transmitted values with predetermined limiting values.
Claim 10
Independent Claim
80 words
The method of monitoring the atmospheric emissions from a plurality of dispersed smokestacks, comprising the steps of: measuring within each stack, certain parameters of the gas flow through the stack which are different from but parametrically related to the emission parameters to be monitored; telemetering to a common remote location the measured parameters from all of the stacks; and data processing the telemetered values at said remote location to derive therefrom indications of the respective emission parameters to be monitored.
Claim 11
Independent Claim
80 words
The method of monitoring the atmospheric emissions from a plurality of dispersed smokestacks, comprising the steps of: measuring within each stack, certain parameters of the gas flow through the stack which are different from but parametrically related to the emission parameters to be monitored; telemetering to a common remote location the measured parameters from all of the stacks; and data processing the telemetered values at said remote location to derive therefrom indications of the respective emission parameters to be monitored.
Claim 12
Dependent Claim
14 words
The method of claim 9 further comprising controlling said telemetering from said remote location.
