Abstract
A method of delivering propane to a customer is disclosed. A transport vehicle transports the propane to the customer. The transport vehicle delivers the propane from the transport vehicle to the customer. A Coriolis flowmeter measures a mass flow rate of the propane as transport vehicle delivers the propane to the customer. The Coriolis flowmeter determines a gross volume of the propane based on the mass flow rate of the propane. The Coriolis flowmeter also determines an adjusted volume of the propane based on the mass flow rate and a constant value. The constant value corresponds to a density of propane at a reference temperature.
Claims17
A method of delivering propane, said method comprising the steps of:
- transporting said propane to a customer using a transport vehicle;
- delivering said propane from said transport vehicle to said customer;
- measuring a mass flow rate of said propane with a Coriolis flowmeter as said propane is being delivered from said transport vehicle to said customer;
- determining a gross volume of said propane based on said mass flow rate and providing said gross volume;
- and
- determining an adjusted volume of said propane based on said mass flow rate and a constant value and providing said adjusted volume, wherein said constant value corresponds to a density of propane at a reference temperature.
