  • This meter is designed for in-line installation, meaning it mounts directly into the DEF fluid line so that fluid passes through it as it is dispensed, measuring flow in real time.

  • The meter is resettable, so you can zero the reading between dispenses to accurately measure and record each individual transfer independently.

  • This is an electronic meter, providing an electronic readout of the DEF volume dispensed rather than a mechanical dial or register.
