APPLICATIONS MAJOR TARGETS GasCVD is a custody transfer devise to realize fair deal under calorific value determining. Especially in Europe, a lot of inlets as to natural gas from Africa, Russia, and East and West Europe. The customers expect to realize fair deal by real time calorific value measurement. Main Pipe line Local pipe line Primary network for natural gas Megadeal customers ex. Power plants Pressure regulator Gas chromatgraphy with OIML R140 Secondary network for natural gas Flow meaurement GasCVD with OIML R140 End users

1. APLICATIONS THE OTHER POTENTIALS Combustion efficiency improvement for gas turbines Gas turbine manufacturers use gas chromatgraphs to measure gas composition for gas turbine. But gas chromatgraph needs a lot of time to analyze gas composition, the customers expect real time, fast response calorific value measurement to improve combustion efficiency. LNG satellites LNG satellites control gas calorie before providing the customers. A lot of calorimeters are used in the sites.

OIML R 140 and WELMEC compliant device Can be used as a calorimeter or calorific value determining device (OIML R140 CVDD) for natural gas.

(2) Innovative structure compatible with various installation sites • Unlike conventional gas calorimeters, GasCVD is innovative small and lightweight, allowing a variety of installation site choices. • Explosion-proof structure is compliant with IECEx and ATEX, and suitable for Zone 1 use.

(3) Revolutionary continuous measurement, and fast response Can detect a change of calorific value in processes in near real time by measuring every 2s. The time constant for 90 % response is within 30 seconds (sample flow rate: 50 ml/min) resulting in very fast output of natural gas calorific value.

(5) A wealth of diagnostic functions • Ambient temperature diagnostic function. Determines whether the operating environment is suitable, making use of a temperature sensor embedded on the same chip as the thermal conductivity sensor. • Operation time tracker function. Keeps track of the total operation time for comparison with the recommended replacement period (70000 hours) for the calorimeter. • Automatic calibration history check function. Shows up to 5 of the latest automatic calibration records to check changes in the calibration factor. Menu for diagnostics in HART ver.7.0
