Gas meter water column.

Inches of water column. There are 28 inches of water in 1 psi so it is a fairly small amount of pressure pounds per square inch psi used for measuring gas pressure in the distribution system and other areas where pressure exceeds the traditional 7 wc. At this point the pressure is regulated down to 5 psi for very large consumers 2 psi for somewhat smaller consumers however most consumers use 7 inches of water column from the meter to the appliance. Gas pressures upstream of the meters is something that gas furnace technicians are not concerned with.

This is why water column is most often used to measure pressures under 1 psi. 4 12 2018 1 units of measure inches of water column wc inches of water column is the traditional method for measuring natural gas or propane. This is fed into a furnace gas valve to regulate the correct pressure for the furnace. The point it comes into a home the pressure will be 7 to 10 inches of water column.

0 150 psi 4 5 out of 5 stars 189. Gas is piped around the country at high pressure and stepped down as it comes into a home. Digital handheld manometer hvac air vacuum gas differential pressure gauge meter tester 11 units with backlight 13 78kpa 2psi 1 2 pipes ventilation air condition system measurement 4 5 out of 5 stars 145. 1 pascal is equal to 0 10197162129779 water column or 0 00014503773800722 psi.

You can view more details on each measurement unit. While some water manometers water tube are still in use the vast majority are either dial or digital gauges that still use the same scale. Water column or psi the si derived unit for pressure is the pascal. Natural gas pressure at the gas meter.

The piping must be sized sufficiently enough so that the pressure drop is a half an inch of water column or less when all the gas appliances are on. These low pressures are most often read using a manometer or a magnahelic gauge. A typical residential gas system is a low pressure system meaning that the home is supplied with a gas pressure around 7 in. We assume you are converting between water column millimeter and pound square inch.

1 psi is equal to 27 71 inches of water column.
