Abstract
The present invention relates to an apparatus and method for upgrading fluid meters with improved modular check valve technology. The check valve module is secured within the meter using only external fasteners. The check valve module may also include a seal. The seal may be inspected by simply removing the external fasteners securing the check valve module within the enclosure and removing the check valve module from the enclosure. The check valve module may include a test port for testing the operation of the check valve. Additionally, a module insert is disclosed comprising a screen module, a metering module, a check valve module, and a bypass arm for dual metering solutions. The module insert may be installed in meter housing connected to a fluid delivery system or new meter housing. Additionally, the module insert may be constructed from materials substantially free of lead.
