Read MoreA pressure gauge is usually located on the front of your boiler and should have a green and red section that can be used to detect when the pressure is too low, too high or just right. The force that it's calculating is that of the hot water that's running through the sealed system. Most boilers should run between one and 1.5 bar of pressure.
Read MoreMany systems run under an ounce or two of pressure (<0.125 psi) before the radiator vents start closing. That likely won't register on a 3psi gauge. You might be in the low pressure club. If you want to know what pressure you're operating at, go to a lower pressure gauge. Also, I would leave the valve open for the whole test.

Read MoreFeb 26, 2004 · Joe Hohn. Feb 26, 2004. #3. Any gauge with a range equal to approximately twice the setting of the boiler safety relief valve should work. In steam service I prefer gauges with a blowout port on the back, just to be extra safe. I do not recommend the use of a diaphragm seal. Standard gauge materials of construction are suitable for steam service.

Read MoreSince steam boilers are under pressure, differential pressure transmitters (e.g. ABB type 266MST) must be used for level measurement in order to compensate for the vessel's overpressure. To make sure during this differential pressure management that hot steam does not condensate at the colder offset side of the transmitter in an undefined way
