In manufacturing, changeover is the process of converting a line or machine from running one product to another. Changeover times can last from a few minutes to as much as several weeks in the case of automobile manufacturers retooling for new models. Reducing changeover times became a popular way to reduce waste in Lean manufacturing after Taiichi Ohno and Shingo Shigeo popularized the SMED (single-minute exchange of die) method in the, now famous, Toyota Production System (TPS). The terms set-up and changeover are sometimes used interchangeably however this usage is incorrect. Set-up is only one component of changeover. Example: A soft drink bottler may run 500 ml glass bottles one day, perform a changeover on the line and then run 750 ml plastic bottles the next day.
Propane () is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is often a constituent of liquefied petroleum gas (LPG), which is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation; other constituents of LPG may include propylene, butane, butylene, butadiene, and isobutylene. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane has lower volumetric energy density than gasoline or coal, but has higher gravimetric energy density than them and burns more cleanly.
Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it vaporise inside pressurised liquid containers (it exists in two phases, vapor above liquid). It retains its ability to vaporise even in cold weather, making it better-suited for outdoor use in cold climates than alternatives with higher boiling points like butane. LPG powers buses, forklifts, automobiles, outboard boat motors, and ice resurfacing machines, and is used for heat and cooking in recreational vehicles and campers. Propane is becoming popular as a replacement refrigerant (R290) for heatpumps also as it offers greater efficiency than the current refrigerants: R410A / R32, higher temperature heat output and less damage to the atmosphere for escaped gasses - at the expense of high gas flammability.

Good Two Stage Regulator with high flow rate and auto-changeover. Easy to connect to existing setup to replace older leaking regulator. Having the MT indicator is a plus for quick status check of propane supply.

Be careful of the 2 spring valves going to each tank, I had one that fell apart. It wasn’t a problem for me because my two hoses going to each tank had the valves in them. The regulator has been working well.
