We carry a full range of pressure gauges for your kiln or furnace. Diaphragm gauges are more sensitive and delicate. Depending on the location of the gauge, you will get one of these types of readings all of which can be different. Gauge Pressure varies depending on orifice size. It is a reference number only and does not actually measure flow.
Manifold pressure is the pressure used to determine orifice sizing and BTU output.
The only device that can accurately measure gas flow is a flow meter. Waukee is the industry leader in the manufacturing of flow meters. With this meter, you can balance burners precisely and determine exactly how much fuel you're using. Meters are sized according to burner output and fuel type. Listed below are three of the most common sizes for kilns and furnaces.
