Applications
For use in measurement of potable cold water in residential, commercial and industrial services where flow is in one direction only
Main casing
Main casings are made of a copper alloy containing not less than 85% copper such as UNS C83600 or a similar copper alloy as listed in ASTM B584 and SDWA 141.43 No Lead. The serial number is engraved on the body. The main case also shows the name of the manufacturer (IMC), and direction of flow
Register
The combined gear and register unit is fully sealed, liquid filled, with a straight odometer for visual reading. For extended life the register unit is manufactured with a direct drive assembly and gears.
Measuring chamber
Measuring chamber is an oscillating piston type and is made of engineering plastic, such as polyethylene ether (PPE) per ASTM D4349, nylon (N) per ANSI/ASTM D4066, polyethylene per ASTM D1248, or polystyrene per ASTM D4549.
Measuring chambers have sufficient dimensional stability to retain operating clearances at working temperatures of up to 120°F (49°C) and shall not warp or deform.
