Monitors / Controllers OVERVIEW

9023-tank-teller-monitorElectronic Sensors, Inc. (ESI) provides Level Devil ® American-made tank monitors, for local or remote tank monitoring — including some of the industry’s most popular sensor controller units. We have systems for single-tank or multi-tank installations (and most of our multi-tank controllers are also available in lower-cost single-tank versions).

Remote monitoring is available via celluar, landline, satellite, Ethernet, or serial/RS-232 communications — reaching your cellphone, smartphone or computer from virtually anywhere (using solar, battery or AC power). Local 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 switches, pumps, relays and other devices.

Select the units you want from our current line of monitor/controller units (click on the model name or number for details).
