Frequently Asked Questions

Q. "What does 45 LT stand for. I am not sure what the LT means?"
A. Years ago the LT referred to the old gas light systems. The LT is simply referring to the size of a particular fitting. For example:

      45 LT = 1 1/2" connection size
      30 LT = 1 1/4" connection size
      20 LT = 1" connection size
      10 LT = 3/4" connection size

Q. "What is FNPT?"
A. FNPT or Female National Pipe Thread is a U.S. standard for tapered threads used to join pipes and fittings.

Q. "What is the advantage of purchasing a temperature compensating gas meter?"
A. Gases are more difficult to measure than liquids, because measured gas volumes are highly affected by temperature and pressure. Gas meters measure a defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter. Temperature, pressure and heating value compensation must be made to measure actual amount and value of gas moving through a meter.

Temperature compensation meters are used more often with LPG gas because LPG tanks are located above ground where the tanks can be directly and quickly affected by the outside temperature. As the temperature is increased the gas will expand in volume but this creates less concentration of the actual heating capacity of the gas. IF the expanded gas travels through a non-compensating meter, you would be charged more based on volume and not actual heating capacity.
