Optical Gas Imaging Camera Calibration and Maintenance
Over the next few months, we will discuss aspects of the EPA’s proposed Appendix K and the advantages of Optical Gas Imaging (OGI) to Oil and Gas producers.
Compared to gas detectors or “sniffers,” OGI cameras aim to significantly reduce methane and VOC emissions by detecting and visualizing the leak quickly and more effectively, ensuring a fast response to any leak.
Paragraph 7 of the proposed Appendix K states that an OGI camera does not require routine calibration for gas leak detection but may require calibration if used for thermography.
Opgal’s EyeCGas 2.0 OGI camera is maintenance-free; it does not require routine calibration and hence has an extremely low cost of ownership.
Although the EyeCGas 2.0 has a thermography function, thermography is not a requirement for gas detection. Therefore, the camera will not need calibration unless explicitly used for temperature measurement.
In contrast, a calibration schedule for a gas detector is a daily bump test accompanied by a monthly calibration. Approximately 1 in every 2,500 untested sensors will fail to respond to a dangerous gas concentration.*
