A mercury pressure gauge is a type of manometer using mercury as the working fluid. The most basic form of this instrument is a U-shaped glass tube filled with mercury. More complex versions deal with very high pressure or have better means of filling with mercury. Meer weergeven The instrument consists of a glass U-tube half-filled with mercury. One end is connected to the vessel whose pressure is being measured. The other may be either left open or sealed. If it is left open, the pressure … Meer weergeven The initial filling of a sealed gauge with mercury can be problematic. One method involves fusing the glass of the gauge to a vessel of mercury, pumping out the air and boiling the … Meer weergeven The parent of all mercury pressure gauges is the mercury barometer invented by Evangelista Torricelli in 1643. An early engineering … Meer weergeven • McLeod gauge, a type of mercury pressure gauge used for calibrating electronic pressure gauges Meer weergeven For extremely high pressures, the column can still be very high, even when using mercury.
