Electronic Line Leak Detection

Electronic Line Leak Detection

Solves your mechanical Leak testing Problems
Intelligent electronic systems virtually eliminate "False Alarms"
Self-diagnostic system - eliminates the required functional testing for mechanical leak detectors
No site shutdown to perform 0.38 lph test 

Saves you money
Electronic systems have long life expectancy with less moving parts to fail which saves you time and money
Cost savings typically present a 2-3 year payback on investment 

Lower your installations and maintenance costs 
PLLD Sensor installs directly in sub-pump
No need to break down pipe work
Integrates with TLS-350 and TLS-350R Tank Monitoring Systems
