Using This Trainer The Function Of A Normal Expansion Vessel Is Examined And A Pressure-Volume Characteristic Recorded. The Expansion Vessel Is Filled With Water From A Supply Tank.
The Pressure Is Generated Using A Small Compressor And Adjusted Using A Pressure Regulating Valve. The Amount Of Water Taken Up By The Expansion Vessel Is Read On A Scale On The Supply Tank.
