2. Product Description
The ELS2Electrolyte Level Sensor is a non-invasive level sensor with incorporated temperature
monitoring designed for quick installation and easy set up. This device complies with the NERC PRC-005
requirements for electrolyte level inspection. With this sensor, you eliminate unnecessary remote site
visits and will eliminate the required quarterly inspection of battery electrolyte level in your battery
string.
An ELS2system will include one sensor module to be attached to each cell for monitoring electrolyte
level and temperature. Each of these modules will be connected back to a system interface module
called the ELSi2 for processing of data for alarm analysis and reporting.
