Water column or psi the si derived unit for pressure is the pascal.
Gas meter water column.
Depending on the application gas meters may operate at 7 w c 0 5 to 2 0 psig or at pressures over 2 0 psig.
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.
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.
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.
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.
A typical residential gas system is a low pressure system meaning that the home is supplied with a gas pressure around 7 in.
Natural gas pressure at the gas meter.
After the gas goes through a gas valve it becomes what is called manifold pressure.
These low pressures are most often read using a manometer or a magnahelic gauge.

Natural gas in the natural gas service line pressure in the gas main in the street will be found at pressures from 60 psi down to as low as 0 25 psi or about 7 inches of water column.
1 pascal is equal to 0 10197162129779 water column or 0 00014503773800722 psi.

Gas pressures upstream of the meters is something that gas furnace technicians are not concerned with.
You can view more details on each measurement unit.
The point it comes into a home the pressure will be 7 to 10 inches of water column.
This is fed into a furnace gas valve to regulate the correct pressure for the furnace.
Gas is piped around the country at high pressure and stepped down as it comes into a home.
1 psi is equal to 27 71 inches of water column.
Inches of water column.
We assume you are converting between water column millimeter and pound square inch.
