- Abstract
- A thorough investigation has been performed to find out if an ellipsodial radiometer (Gunners meter after its developer) can be used for separating radiation and convection when calibrating heat flux meters in open configurations and when calibrating flux levels in fire test methods. It is demonstrated in the present investigation that the Gunners meter can be used for this purpose. However, the Gunners meter used had an inconsistent behavior and it was found that the design must be modified to improve the angle response. The application of the results obtained are discussed and tentative guidelines for calibration and use of heat flux meters are outlined. However, it must be noted that futhre work is needed before a more stringent version of the guidelines can be formulated.
