Real natural gas or ideal gas.. there is a difference.

• You develop gas flow meter computer system?
• You develop electronic devices for a gas industry?
• You need the chip for natural gas compressibility factor and density calculation?

• Detail characterization method using American Gas Association Report #8

( Starling K.E., Savidge J.L. Compressibility Factors of Natural Gas and Other Related Hydrocarbon Gases / AGA Transmission Measurement Committee Report No. 8. - 1994.- Pp.204)

• Available packages: PLCC(68).
• Commercial or industrial temperature range.
• Simple connection.
• Only one chip (microcontroller PIC17C756). Clock frequency up to 33 MHz.
• Serial or parallel data exchange [coprocessor commands].
• You transmit in to the chip pressure, temperature and gas composition (up to 21 components).

• Receive compressibility factor and density.

At clock frequency 10 MHz:

• Typical calculation time - 60 ms.
• Maximum calculation time - 150 ms.
• Maximum additional calculation time if composition changing - only 600 ms.
