The CTS Battery Operated Multi-Compartment Fuel Tank Alarm system has three functions; to detect and warn of a fuel storage tank overfill, a high/low liquid level and a bund leak. If the tank level alarm identifies that any of these states have occurred, the channel in question will illuminate on the alarm’s screen, and a loud siren and flashing red light will go off. When its battery is low, this level bund alarm will sound a single beep every minute to alert the user of this.

Thanks to being battery powered, these fuel tank alarms are designed to be installed on isolated or portable systems, and each channel can be configured allowing the alarm to be customised by the installer. Options are available that come with three relays, allowing additional equipment to be connected to the tank level alarm such as larger alarm systems or building management systems for remote monitoring.

The CTS Battery Fuel Tank Level Alarm box has undergone a redesign for the convenience of the tank manufacturer/installer. It benefits from the same functionality the market knows and loves, but now with external mounting lugs for installation without opening up the tank alarm box, captive screws to prevent accidentally dropping and losing them in the bund and improved cable gland positioning.

If you need a tank level alarm for a fluid other than diesel or light oil, also available are a water and chemical alarm probe, and a high viscosity oil tank level probe – which is also suitable for AdBlue as well as high viscosity oils. Please see the accessories table.

Please note: Codes SWS4000 and SWS4001 do not come complete with probes. Please view the accessories table to select the combination you need. All cables must be free of electrical noise.
