Vaporless - Model ISM-4080 and ISM-4081 -Integrated Shutdown Module
The ISM-4080 and the ISM-4081 Integrated Shutdown Modules are built using the field proven technology of the ARM-4073 Automatic Repressurization Module. Auto-Repressurization technology (patent application), developed by VmI, prevents leak detector false alarms. The ISM-4080 and ISM-4081 integrate Auto-Repressurization with real time pressure monitoring to determine when thermal contraction is occurring and compensation is required.
Submersible Shutdown at Catastrophic Line Leak Detection
When the mechanical leak detector senses a leak, the turbine authorization is removed and alarm contacts are authorized.
Automatic Line Leak Test
The ISM-4080 and ISM-4081 automatically monitors line leak tests before dispensing product and monitors Auto-Repressurization tests between deispensing cycles.
Manifolded Pumping Systems
Controls multiple submersibles manifolded into one line! Brings manifolded pipe systems into compliance using a leadlag submersible contro for any number of manifolded submersibles.
- No Interference with Automatic Tank Testing
- Line Leak Monitoring Reports through Automatic Site Monitoring Equipment
- Sump Sensor Monitoring
- External Bypass Switch
ISM-4080 - Automatic shutdown of the submersible pump is a wump sensor alarm is detected.
ISM-4081 - For use where submersible pump shutdown is not desirable (and not required) if the sump sensor is activated. Allows a choice of alarm only response or submersible shutdown if a sump sensor alarm is activated. The Leak Detector Sensor (Low Pressure) alarm will still shut down the submersible pump following detection of a catastrophic line leak.
