The commonly available Monument-brand water pressure gauge (eg Screwfix ref 82412 @gbp11.99) measures up to 11bar. What I'm trying to measure is pressure after the pump on a gravity fed CH system which the Monument only uncertainly indicates at around 0.5bar.
Is there a water pressure gauge which measures sub- 1bar pressures reasonably accurately?
TIA
How about a 2 bar gauge?
manometer? just get about 15ft of plastic clear tubing and string it up vertically.
0.5 bar is about 16 ft of head.Nick a boost gauge off a scarp turbocharged car?
