摘要:
A method for correcting data signal errors in a meter has been developed. The method includes receiving ordered data signals from the meter. Next, the sequenced of ordered data signals is analyzed to determine whether a data signal is missing. Finally, if a data signal is missing, a predetermined value is added to a sequence counter to compensate for the missing signal.
摘要:
A measuring meter system with communications and features protocols for monitoring the meter has been developed. The system includes a meter that monitors usage of a distribution system, an electronic data recorder that processes data from the meter, and an external unit that controls the processing of data in the electronic data recorder with a communication protocol. The communication protocol includes an initialization signal, an interval identification signal, and a clock signal.
摘要:
A below-grade fuel delivery and storage system is constructed in the form of a fully vaulted system located under the dispenser area. The vault is made of concrete; and all of the plumbing, fill, vapor recovery locations and the bulk storage tank itself are located entirely within the vault. The fill pipes for tanks located within the vault extend through openings in the roof of the vault. Similarly, fuel delivery lines extend from the tanks upwardly through openings in the vault roof to dispensers located directly above the vault.
