with a Roots® Rotary Gas Meter and Model CEX Electronic Transmitter
The MASStrol utilizes the pressure and temperature signals, as well as user input data, to compute the density of the flowing natural gas. The MASStrol then performs a calculation that is referenced to standard conditions. The result of the calculation is displayed in SCFM or NM³ per hour and totalized in SCF or NM³. The MASStrol can be programmed to calculate the volumetric flow to any desired pressure and temperature base conditions. The MASStrol can provide displays of mass flow, heat flow, mass total, heat total, pressure, temperature, specific volume and specific enthalpy.
