Submersible Level and Temperature Smart Sensor

Overview

The Seametrics LevelSCOUT Smart Sensor is an integrated datalogger and level/temperature sensor and is ideal for site assessments, tidal studies, environmental monitoring, surface water discharge measurement, and aquifer level monitoring, as well as aquifer storage and recovery. This sensor networks with all of the Seametrics Smart Sensor family. Its compatibility with Seametrics' Wireless Data Collection technology makes it ideal for remote monitoring.

This industry standard digital RS485 interface device records up to 50,000 records of level, temperature, and time data, operates with low power, and features easy-to-use software with powerful features. Constructed with 316 stainless steel, acetal, and Viton®, this sensor provides high-accuracy readings in rugged and corrosive field conditions. The LevelSCOUT is an absolute sensor, requiring no vent tubes, desiccant, or bellows. It can be paired with a BaroSCOUT barometric sensor and used with the Aqua4Plus Barometric Compensation Utility to adjust the LevelSCOUT readings for current atmospheric pressure.

A 1/2 AA 3.6v lithium battery powers the LevelSCOUT. The unit is programmed using Seametrics’ easy-to-use Aqua4Plus Lite or Aqua4Plus control software. Once programmed the unit will measure and collect data at the time interval programmed. While most will use the LevelSCOUT with Seametrics' Aqua4Plus Lite or Aqua4Plus software, it is by no means limited to that software. You can use your own Modbus® RTU software or logging equipment to read measurements via RS485, tying into your existing systems and databases.
