LPG and LNG Measuring Systems

Unlike the systems for traditional fuels, the LPG measurement systems on tank trucks and, especially those of LNG, are more complex and dependent on the tank where they will be located. For these cases, CETIL offers the main components that make up the system, as well as all its experience and knowledge in the measurement and transfer of fuels. In this type of systems, especially in LNG, mass meters play a fundamental role. Our electronic calculator ME4000 is able to extract all the necessary information from this type of meters guaranteeing a correct measurement and thus allowing to control the entire measurement system: meter, valves, pump, printer, POS, emergency stops, etc.

LPG Measuring Systems general characteristics

  • Positive displacement volumetric meter or high accuracy mass meter.
  • Maximum flow of 380 l/min with volumetric meter or 750 kg/min with mass meter.
  • Filter before meter, gas eliminator, aircheck valve and differential valve to guarantee the measurement.
  • Predetermination of the quantity to be delivered.
  • Electronic calculator ME4000.
  • Configurable hose length and diameter.

LNG Measuring Systems general characteristics
