Gas Meter Water Column

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.

Gas meter water column.

Gas pressures upstream of the meters is something that gas furnace technicians are not concerned with. This is fed into a furnace gas valve to regulate the correct pressure for the furnace. 0 150 psi 4 5 out of 5 stars 189. 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.

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. Inches of water column. Gas is piped around the country at high pressure and stepped down as it comes into a home.

We assume you are converting between water column millimeter and pound square inch. You can view more details on each measurement unit. 1 psi is equal to 27 71 inches of water column. Water column or psi the si derived unit for pressure is the pascal.

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. These low pressures are most often read using a manometer or a magnahelic gauge. This is why water column is most often used to measure pressures under 1 psi. After the gas goes through a gas valve it becomes what is called manifold pressure.

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. 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. 1 pascal is equal to 0 10197162129779 water column or 0 00014503773800722 psi. 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.
