OxyTrak flue gas oxygen analyzer
OxyTrak, an in situ flue gas oxygen analyzer, is self calibrating and requires no reference air. It uses a unique, miniaturized zirconium-oxide sensor with a sealed internal reference to accurately determine flue gas oxygen content, even with rapidly changing process conditions. With the sensor acting in “pump” mode, the current needed to maintain partial pressure equilibrium is proportional to the oxygen content. In addition, the Nernst voltage present during transients is used to instantly indicate the magnitude of oxygen content changes. The small sensor size allows the measurement inputs to reach equilibrium quickly, providing superior speed of response. The unit is designed for in situ installations with variable probe lengths up to 60 in. (153 cm). The advanced microprocessor- based electronics package features: an infrared, through-the-glass keypad; a universal power supply (85–264 VAC); 0/4–20 mA or 0–2 VDC analog output; dual alarms; a fail-safe alarm; and an RS232 or RS485 serial output.

DigitalFlow DF868 flowmeter
The Bundle Waveguide Technology (BWT) system with the DigitalFlow DF868 flowmeter measures LNG flowrates in pipes ranging from 2 in. to 48 in., and is touted as the only solution for measuring LNG flows in pipes greater than 8 in. The system measures cryogenic flows of LNG at –161°C (–322°F) as it is transferred from liquefaction trains and tankers into storage tanks at production plants and receiving terminals. The Sentinel is a naturalgas ultrasonic flowmeter specifically designed to meet the demands of high accuracy, fiscal custody-transfer measurement. It is used for metering natural gas fed to production liquefaction trains and re-gasified LNG at receiving terminals, or for any natural gas measurement where high accuracy is needed. It is a multipath ultrasonic flowmeter available in pipe sizes ranging from 6 in. to 48 in., and meets AGA 9 criteria. It is delivered as a complete system with matched upstream pipe run and flow conditioner.
