The standard CEM system consists of a sample probe, filter, sample line , gas conditioning system, calibration gas system, and a series of gas analyzers which reflect the parameters being monitored. Typical monitored emissions include: sulfur dioxide , nitrogen oxides , carbon monoxide , carbon dioxide , hydrogen chloride , airborne particulate ...
A Discharge Monitoring Report (DMR) is a United States regulatory term for a periodic water pollution report prepared by industries, municipalities and other facilities discharging to surface waters. [ 1 ] : 8–14 The facilities collect wastewater samples, conduct chemical and/or biological tests of the samples, and submit reports to a state ...
This is done by using a downhole "pulser" unit which varies the drilling fluid (mud) pressure inside the drillstring according to the chosen MPT: these pressure fluctuations are decoded and displayed on the surface system computers as wave-forms; voltage outputs from the sensors (raw data); specific measurements of gravity or directions from ...
The common ground for monitoring and evaluation is that they are both management tools. For monitoring, data and information collection for tracking progress according to the terms of reference is gathered periodically which is not the case in evaluations for which the data and information collection is happening during or in view of the ...
Often visual inspections are considered to form an underlying component of condition monitoring, however this is only true if the inspection results can be measured or critiqued against a documented set of guidelines. For these inspections to be considered condition monitoring, the results and the conditions at the time of observation must be ...
Shock pulse method (SPM) is a technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in 1969 it has been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance.
Monopulse radar is a radar system that uses additional encoding of the radio signal to provide accurate directional information. The name refers to its ability to extract range and direction from a single signal pulse.
Community-based monitoring (CBM) is a form of public oversight, ideally driven by local information needs and community values, to increase the accountability and quality of social services such as health, [1] development aid, [2] or to contribute to the management of natural resources. [3]
