What must concentrated natural gas motor fuel dispensers measure in terms of flow?

Concentrated natural gas motor fuel dispensers must measure the maximum and minimum flow rates per unit of time to ensure accurate and reliable fueling processes. This measurement is critical for several reasons. First, knowing the maximum flow rate helps prevent overfilling and ensures that the dispensing equipment operates within safe limits. It also assists in monitoring the performance of the dispenser, identifying potential issues, and maintaining compliance with regulatory standards.

Measuring minimum flow rates is equally important, as it helps determine if the dispenser is functioning correctly and efficiently. If flow rates fall below expected minimums, this may indicate a malfunction, clog, or other issues that could lead to service interruptions or safety hazards. Together, monitoring both maximum and minimum flow rates provides a comprehensive understanding of the dispenser's operational performance, helping ensure the safety and reliability of natural gas fueling.
