Dresser Roots 8C Meter
8C175 Series Gas Meters are an accurate positive displacement rotary style gas meter. Additionally, one of the amazing features is a very low differential across the meter. This series meter ranges in sizes from 1-1/2 Inch Male Nipple, and 2 Inch 150# flange connection. Capacity is 800 Cubic Feet Per Hour (800 Thousand BTU). A maximum line pressure of 175 PSI (notice that in the model number). Operating temperatures are -40°F to +140°F (-40°C to +60°C).
Moreover these meters are great for both indoor and outdoor applications. Another fantastic perk is there are no straight pipe requirements. However, it is strongly recommended that you install a Strainer as close to the meter inlet as possible to protect it from pipe debris.
