RM140 - Overfill & Grounding Monitor

Overfill protection and grounding monitor for truck or rail loading in petro-chemical applications. Built to function with all probes designed to the API code: API RP 1004 and the EU Standard EN13922, the RM140 Series is the world’s most flexible and adaptable monitor. 

The RM140 provides state-of-the-art overfill protection and grounding monitoring that is compatible with all commonly used overfill protection and grounding systems.

Known  around the world for its superior reliability and 'bullet proof' design. The RM140 series can detect the type of sensor in the transport, the state of liquid in the tank, an overfill situation, and/or verify the grounding condition.

 

  • Grounding and/or Overfill Monitor in one competitive package.
  • Automatic sensing of 2-wire/thermistor or 5-wire overfill systems.
  • Supports up to (8) 2-wire/thermistor probes and up to (12) 5-wire probes.
  • Self-test at start up/continuous self-monitoring, ensures safety throughout the loading process.
  • Separate grounding and overfill control outputs.
  • Ultra high visibility display provides flexibility for indoor/outdoor use.
  • Full sensor diagnosis at a glance.
  • Coded wireless by-pass key for secure and reliable operation.
  • Built in 110 & 240 voltage selection.
  • Built in 6 or 8 channel selection.
  • Upgradeable software to allow for additional features.

Operation
In order to load the RM140 checks for grounding and overfill status of the gantry/vehicle.

The RM140's ground verification ensures there is sufficient grounding in place to allow loading to occur.

The RM140 checks the overfill status by sending a intrinsically safe signal to the probes in the vehicle asking them if they are dry or wet.

When probes are 'dry', a signal is returned to the monitor. If the signal meets pre-determined characteristics the monitor goes to a “permissive” state which allows loading to occur. If the probe becomes 'wet', the relay is opened and the monitor goes to a "non permissive" state which prevents loading from occurring.
