Temperatures are measured using platinum resistance temperature thermometers and type T thermocouples. Flow measurements are taken with turbine flowmeters mounted in the fluid line. Flow is also calculated using two 2,000 lb. Flow is controlled using two positive displacement gear pumps with 1 H.P. motors and digital motor speed controllers. The computer monitors the laboratory for several alert conditions.
Devices are in place to detect overheating, flooding and overpressurization.
The system is designed to safely shut down if any of these conditions are detected protecting both the laboratory and any equipment currently under test. Exposure and Pressure testing Systems are subjected to outdoor exposure in a fenced security area on site. In case of a conflict between the two recommendations the shorter time period will be used. In no case will the period between calibrations exceed one year.
