Simple system easy handled and completely integrated - No requirement for preventive maintenance or calibration

LNG Plant Applications:

Recondenser outlet for Wobbe and CV measurements

Export Boil off gas / Nat gas blending line to the network

Ballasting control feedback analyser for efficient liquid N2 injection

Cabinet mounting ex situ ad side of Vaporizer cabinet for measurements of:

		Calorific Value • Wobbe Index • Compressibility • Relative Density • Carbon Dioxide • • Speed of Sound (USM Comparison) • Methane Number
		-    Direct communication with PC workstation  / DCS in Control Room. -    Small scale LNG production including production of vehicle-grade LNG:  no shelter requirement for sampling/process GC

    Measuring Principle:

-    Speed of sound via unique acoustic resonator correlates with relative density
-    Carbon dioxide measured by NDIR as  molecular weights of carbon dioxide (CO2) and propane (C3H8) are equivalent.
-    Thermal conductivity measured at ambient and  elevated temperatures correlates with calorific value.
 
Performances:

-    ISO 6976 Compliant
-    EN 12 838 discontinue  test compliant:
-    HS maximum random error 54 Kj/Kg 
-    NG density maximum random error: 0.0018 Kg/m3
