"Applicable Codes, Standards and Requirements" means the codes, standards, and/or requirements identified, established, adopted, or published by the American National Standards Institute (ANSI) or American Gas Association (AGA) that are applicable to gas utility meter performance, accuracy, testing, or related matters, or the codes and standards of other entities that are generally accepted and used by the gas utility industry for meter performance, accuracy, testing, or related matters. The applicable version of the codes and standards required by this Chapter shall be the most recent version of the applicable codes and standards. The version that applies to a device will be the version in effect at the time the device is initially put into service.
B. "Billing Conversion Factor" means a factor used to convert cubic feet of gas into Therms, based on the heat content and the delivery pressure of the gas delivered to customers over the applicable billing period.
C. "British Thermal Unit" or "BTU" means the amount of heat required to raise the temperature of one pound of water one-degree Fahrenheit at the temperature that water has its greatest density.
D. "Commission" means the Maine Public Utilities Commission.
E. "Customer" means a person or entity that receives service from a gas utility.
F. "Diaphragm Meter" means a positive displacement instrument which is used to measure the volume of gas that passes through it.
G. "Gas Utility" means an entity that distributes natural gas for end use by customers in the State of Maine.
H. "Heat Content" means a thermodynamic quantity equal to the internal energy of a system plus the product of its volume and pressure.
I. "Rotary Meter" means a gas volume meter with a rigid measuring compartment is formed between the walls of a stationary chamber and rotating element of elements.
J. "Therm" means 100,000 BTUs.
K. "Turbine Meter" means is a liquid/gas velocity measurement device with a free-spinning turbine rotor that turns at a speed that is proportional to the flow velocity.
L. "Ultrasonic Meter" means a device that measures the velocity of gas within the meter ultrasonically allowing flow to be computed.
