The METRIS 250 has valued configuration flexibility by offering three distinct versions:
METRIS 250 Standard
The METRIS 250 meter can be retrofitted into any standard residential meter set. Meter installers appreciate its slim, lightweight construction. Combining the one-piece seamless diaphragm with die cast aluminum construction and lube-free bearing surfaces deliver a meter that is slim, lightweight and appreciated by meter installers.
The "RM" version of the METRIS offers a win-win for the utility company and the homeowner. The homeowner appreciates its clean, simple and compact appearance while the utility company welcomes its performance and the savings associated with diminished installation piping and reduced installation time.
The METRIS RM is the only combination regulator and meter with a meter bar available directly from a manufacturer. This innovative design solves many troublesome meter location issues where space is an issue. The RM has three pressure taps for field maintenance.
The METRIS MB in many cases is the perfect choice for submetering when space concerns are an issue. The gas meter has a back inlet and outlet configuration which allows for tight multiple meter sets, and metering with ease in multi-family units or even high-rise apartment closets. By removing the piping associated with a standard six inch meter, additional space is created for the resident.
Itron I-250 Gas Meter versus Metris Residential Meters
After a 15 year hiatus, Itron is bringing back a classic residential gas meter design (Sprague/Schlumberger/Actaris) to augment their product offerings.
Natural gas meter types: Inferential and Positive Displacement Meters
Gas meter types are grouped into two categories: positive displacement meters (rotary and diaphragm meters) and inferential meters (orifice and turbine meters).
