Fixed Gravity Temperature Volume Compensators

Automatically corrects counter reading for product volume changes due to temperature. Corrects to a net volume at 60 degrees F (15 degrees Celsius). Heavy duty ratchet and pawl speed change mechanism provides longer service life. Thermal sensing system with ambient bellows offsets the effect of outside ambient temperature. Operating range -30 degrees F (-34 degrees C) to +120 degrees F (49 degrees C). Factory set LPG at .505 specific gravity. Removable temperature sensing bulb enable field check for accuracy of thermal sensing system. Field repairable to minimize downtime.
