Model OT-3 Natural Gas Oxygen measurement - 1

TELEDYNE ANALYTICAL INSTRUMENTS Measuring Oxygen in Natural Gas • Controls quality • Prevents corrosion oxygen analysis ranges and is acceptable for operation in Class I, Division 2, Groups B, C, and D hazardous environments when used in conjunction with a non-incendive power source. The OT-3 system is housed in a weatherproof NEMA-4 case. For access to the Micro-fuel Cell and transmitter controls, the front door swings open. The OT-3 is designed to work with a variety of Flow Computers, such as TotalFlow or FlowBoss, and the system can be ordered in either AC or DC powered versions. Designed to Measure O2 in Natural Gas The Challenge At a time when domestic natural gas companies seek to lessen the United States’ dependence on foreign resources and attain greater production from our reserves, Teledyne has supported the mission with reliable equipment for measuring oxygen in natural gas. The OT-3 is designed to run continuously for years with minimal maintenance and streamline the work of field technicians. This innovative instrument utilizes new sensor technology -- Teledyne’s own A-2CNG sensor -- engineered with CO2 resistant electrolyte. Even more exciting, this sensor has a built-in acid gas scrubber (patent pending). The Sensor The heart of the system is Teledyne’s own A-2CNG Microfuel Cell oxygen sensor. This cell is a sealed electrochemical device which translates the amount of oxygen present in a sample into an electrical current. And unlike other sensors on the market, it comes complete with a built-in acid gas scrubber. Features • Two analysis ranges, user selectable • Designed to work in tandem with the predominant FCUs in the industry • Operates at as low as 10 VDC • High sensitivity (0.5% FS) • High accuracy (± 2% of full scale at constant temperature) • Insensitive to flow variation • Fast response and recovery Competitors’ units rely on a bulky, external scrubber that requires frequent maintenance and replacement. Restructuring the sensor to accommodate the scrubber simplifies upkeep while minimizing instrument size. • Long-life maintenance-free Micro-fuel Cell sensor • Rugged NEMA-4 bulkhead mount enclosure The OT-3 Natural Gas Oxygen Measurement System accurately monitors trace oxygen levels in a variety of gases at the ppm level. • Unaffected by reducing agents (HCs, CO, SO2, etc.) • Easy to calibrate; no zero gas required • Stainless steel sample system • Optional heater The transmitter is equipped with two user-selectable Built for Reliability and Performance
