inside steam drums and other high-temperature and pressure
applications can raise some real obstacles to true level measurement.
Here, the author starts by looking at these impediments and some
traditional strategies to compensate for these conditions, and then
he suggests some ways guided wave radar and new compensation tactics
can combine for consistently accurate readings.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
