The SLM-010 Smart Salt Level Monitor from Electronic Design Service (EDS) provides reliable monitoring of salt levels in residential and commercial water softener systems.
Using a compact LiDAR distance sensor and Bluetooth connectivity, the device continuously measures the salt level inside the brine tank and sends alerts when the salt level drops below the configured threshold.
This intelligent monitoring system helps homeowners and service providers maintain water softeners efficiently and avoid problems caused by low salt levels.
With real-time monitoring and smartphone alerts, the SLM-010 eliminates the need for manual tank inspections and guesswork.
The SLM-010 water softener salt level monitor continuously tracks salt levels and alerts users when refilling is required.
Why Salt Level Monitoring Is Important
Water softeners rely on salt to regenerate the resin that removes hardness from water.
If the salt level becomes too low, several problems can occur:
• hard water entering the home plumbing system
• scale buildup in pipes and appliances
• reduced efficiency of the softener system
• potential damage to water heaters and fixtures
A dedicated salt level monitor ensures that the system is refilled before these issues occur.
Typical Applications
The SLM-010 is suitable for many installations including:
• residential water softener systems
• rental properties and vacation homes
• service companies managing multiple softeners
• homes with high water hardness levels
Key Features
• Accurate LiDAR-based salt level measurement
• Bluetooth connection to smartphone or tablet
• Real-time salt level monitoring
• Low-salt alerts and notifications
• Compact installation inside the softener tank
• Compatible with most residential water softener systems
• Durable design for long-term operation
How the SLM-010 Works
The SLM-010 uses a laser-based LiDAR sensor to measure the distance from the top of the tank to the salt surface.
This measurement is used to calculate the remaining salt level inside the brine tank.
The device communicates with a smartphone or tablet using Bluetooth Low Energy (BLE), allowing users to monitor salt levels in real time.
When the salt level drops below approximately 40% of the tank capacity, the system can send a notification reminding the user to refill the tank.
Installation Overview
The SLM-010 installs easily inside the water softener brine tank.
The sensor measures the distance to the salt surface and automatically calculates the remaining salt level.
The monitoring data is transmitted to the SLM-010 mobile application, allowing users to view:
• current salt level
• device status
• system alerts
