MULTI-Tank Monitors/Controllers

Electronic Sensors, Inc. (ESI) provides Level Devil ® American-made tank monitors, for local or remote tank monitoring — including some of the industry’s most versatile and popular sensor controller units.

Our multi-tank systems provide efficient, and feature-rich, monitoring of 2 to 99 tanks per unit. (And some of our multi-tank controllers are also available in lower-cost single-tank versions).

Remote monitoring is available via cellular, satellite, WiFi/RF, Ethernet or Bluetooth® communications — reaching your cellphone, smartphone or computer from virtually anywhere (using solar, battery or AC power).

9023-tank-teller-monitorLocal displays and alarms are also available, and relay boxes extend the functions possible for our monitor/controller units, allowing them to be programmed to control lights, horns, switches, pumps, relays and other devices.
