The Dresser ROOTS 10C25 rotary meter with Digital Instrument Index combines compact design, advanced measurement capability, and reliable long-term performance for modern gas metering applications. Designed for installations where space efficiency matters, the 10C25 offers the performance advantages of larger rotary meters in a smaller and more installation-friendly format. Its streamlined construction makes it especially suitable for applications often served by large diaphragm meters, while delivering stronger accuracy, easier handling, and a more refined footprint.
Built on the proven legacy of Dresser ROOTS rotary meter technology, the 10C25 features an oil-free meter body and is available with the Dresser Digital Instrument Index in non-compensated, temperature-compensated (DI-T), and vault-capable versions. The index is easy to configure, supports multiple pulse output options, and stores more than 150 days of hourly data in non-volatile memory. This makes the meter a strong solution for utilities and industrial users seeking better monitoring, dependable data retention, and flexible integration into metering systems.
The Dresser 10C25 continues the brand’s reputation for dependable accuracy with a proven oil-free design based on the long-standing performance of the 5C15 and 8C15 ROOTS meters. With a start rate of just 0.35 ACFH, the meter quickly reaches 99% accuracy at only 10 ACFH, offering a 1% rangeability of 95:1. This allows it to measure a broad range of gas loads accurately, from very low pilot flows to full-capacity operation. For applications where precise billing, monitoring, and load capture are essential, the 10C25 delivers strong performance in a compact platform.
Testing and proving are also simplified through the Dresser Digital Index. Using a single-cable interface, proving can be completed in less than five minutes without the need for special software or computer programs. An optional low-cost fixture is also available to support testing on common cabinet-type sonic nozzle systems, helping reduce maintenance complexity and service time.
To support upgrades from existing diaphragm meter installations, conversion kits are available for adapting current meter sets to a 10C25-compatible configuration. These kits are offered with or without drain plugs and are designed for quick replacement, reduced installation footprint, and improved measurement accuracy. Compatibility with 8-1/4” and 11” center-to-center IPS connections makes integration easier across a range of existing setups.
