Which Veeder Root model do you recommend for my application?
Choosing the best automatic tank gauge for your application largely depends on the number of tanks that you need to monitor. The Veeder Root TLS-4c is capable of monitoring 2 tanks and TLS-4i is capable of monitoring 4 tanks. This limitation is based on the number of sensor inputs available to each tank. At a minimum, each tank requires a level probe, sump sensor and interstitial space monitor. The Veeder Root 450PLUS is capable of monitoring up to 64 tanks and can track 99 sensors of any one type.
