Utility gas custody transfer and fiscal metering customers need flow readings that hold up to scrutiny, and that means catching any pulse miscount, not just measuring volume. The Contrec 515 GC01 Ideal Gas Flow Computer is built for this, using a frequency volume flow input with dual-channel quadrature tracking.
It takes the frequency flow signal along with temperature and pressure inputs, and works out gas compressibility and actual gas quantity in real time using standard equations of state, so the volume and mass reading reflects real gas behaviour, not an assumed constant density.
The quadrature input gives ISO 6551 Level B pulse security, so pulse miscounts on the flow signal are caught rather than silently passed through, which matters for fiscal loops and custody transfer operations where the numbers need to be defensible. It comes in a weather-tight IP65 housing built for field use.
Before we quote this, we would normally check your flowmeter’s quadrature output, your gas composition, and your line pressure and temperature.
Hope this helps.
