Dresser Temperature Compensated Accessory Unit

Temperature compensation, available in meter sizes 8C-16M, is accomplished by a mechanical computer with a spiral bi-metallic thermocouple (probe) located in a sealed temperature well at the meter inlet. Series 3 TC Units provide corrected gas volume readings to a 60˚F (15˚C) base temperature for readout in Standard Cubic Feet (SCF) or Normal meters cubed (Nm3) between flowing temperatures of -20˚F and +120˚F (-29˚C and + 49˚C). 

Dresser Series 3 Meter Accessory Units are designed for low maintenance and a long service life. They are permanently lubricated for long life and virtually maintenance-free operation. They also have a durable and weather-resistant cover with improved sealing capability.
