![]() ![]() If you are not at sea level, call your local gas regulators distributor, and they will assist you in sizing a regulator for your applications. ![]() If you do not receive a prompt email for your applications, check your spam mail. The program quickly selects two regulators for this application by answering this. Natural gas: Btu/hr Propane: Btu/hr Butane: Btu/hr SCFH standard cubic feet per hour (at 14.4 psia sea-level atmospheric pressure at 60F) Altitude Effect in Gas Regulator. Available Inlet gas pressure: 2PSIG – 5PSIG min-max.Go to the regulator sizing program and enter the following information: The following is the selection information we’ve gathered for an application we desire to have sized. Here, I introduce the Itron Regulator Sizing Program with the caveat: this program works for sea-level applications and does not consider altitude effects. In “ How to select the correct gas pressure regulator?” I revealed how we use our selection information and sizing charts to select the appropriate regulator for our applications. Regulator Sizing Program for Itron Regulators However, along the Colorado Front Range, a cubic foot of natural gas is about 830 BTU. One CFH of natural gas at sea level is approximately 1000 BTU/hour. Assuming that the Colorado Front Range elevation is about 1608 meters (5300 feet), it would mean that there is an approximate 21% reduction in pressure from a sea-level location. SCFH – standard cubic feet per hour (at 14.4 psia - sea-level atmospheric pressure at 60F)Ītmospheric pressure reduces with altitude, so we need to ascertain the regulator location to determine elevation.Īs we increase elevation by 300 meters (approximately 1000 feet), there is an approximate 4% reduction in atmospheric pressure.Where SCFH=standard cubic feet per hour, BTU=British Thermal Unit, and MBH=1000 times BTU The capacity, flow rate, or gas load is the end user’s requirement to be supplied, measured in SCFH, BTU, or MBH.The desired or regulated outlet pressure measured as above.W.C.), or ounces (oz.) (Keep in mind that 1 PSI = 16 oz. Available Inlet gas pressure measured in pounds per square inch gauge (PSIG), inches of water column (in.Six parameters help size and recommend the most suitable regulator for various applications. Pressure regulators reduce, control, and maintain the pressure of a specific portion of a pipe system.Service regulators reduce service line gas pressure to delivery pressure.Line gas regulators are between a service regulator and an appliance regulator on a gas line.Appliance regulators control the gas pressure of an appliance.Gas regulators control gas pressure, and they help in four primary applications: Pressure of 14.Itron B42 Residential Regulators for Natural Gasīefore sizing and choosing a regulator, know what purpose the regulator will serve. ![]()
