Abstract:
A stack gas emissions monitoring system process for measuring volumetric gas flow using an electronic data logger, a remote control electronically connected to the data logger controlling the operation thereof, a probe having first and second gas pressure sensing electronic transducers each having an output connected to the data logger, and an electronic temperature sensing transducer having an output connected to the data logger; the remote control including an electronic display panel and a ""read"" switch to record the transducers' output in the data logger, comprising the steps of: positioning the probe at a predetermined position within a vertical stack having gas flowing upwardly therein; closing the read switch on the remote control to store the probe values within the data logger; repositioning the probe within the stack at the same vertical elevation as the previous reading; closing the read switch to store the probe values within the data logger; repositioning the probe within the stack to other predetermined positions within the stack at the same vertical elevation and storing the probe output at each position within the data logger; and transferring the stored data from the data logger to an evaluation apparatus for measuring volumetric gas flow, the remote control including a forward switch, a reverse switch, and first and second indicator lights; the forward switch advancing the data logger to the next gas sensing position and the reverse switch returning the display to the last position reading.
