Theory of Operations – Mass Flow

� Three-wire platinum RTD measures tube temperature on inlet side of sensor– Accurate to +/- 1.0oC

– Available as additional process variable

� Flow Calibration factor captures the proportional relationship between flow and the measured phase shift– Same factor for liquid or gas

– Linear over entire range

– Also contains the factor used with the RTD measurement for temperature correction

Direct Density Measurement

Density measurement is based on the natural frequency– As the mass increases, the natural frequency of the system decreases– As the mass decreases, the natural frequency of the system increases

MID approval &calibration

Water massflow test at the Ede plant at 20oC, plus water density tests between 20oC and 55oC to determine the unique DT and calculate FT from DT. No field calibration is required.

Liquefied natural gas or LNG is natural gas natural (primarily methane , CH4) that has been converted to liquid form for ease of storage or transport.

Liquefied natural gas takes up about 1/600th the volume of natural gas at a stove burner tip. It is odorless, colorless, non-toxic and non-corrosive.

The liquefaction process involves removal of certain components, such as dust, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure (Maximum Transport Pressure set around 25 kPa by cooling it to approximately −162 °C.

The reduction in volume makes it much more cost-efficient to transport over long distances where pipelines do not exist. Where moving natural gas by pipelines is not possible or economical, it can be transported by specially designed cryogenic sea vessels (LNG carriers) or cryogenic road tankers.
