Station operators now have automatic notification of line leaks, not thermal problems. No more drive-off customers from thermal problems! The ISM-4080 Integrated Shutdown Modules are built using the field proven technology of the ARM-4073 Automatic Repressurization Module. Auto-Repressurization technology (patent application), developed by Vml, prevents leak detector false alarms. The ISM-4080 integrate Auto-Repressurization with real time pressure monitoring to determine when thermal contraction is occurring and compensation is required.
