SALINOMETER DS-20 | ALFA LAVAL Boiler Water Salinity Monitor | Marine Salinity Alarm System | SM MARINE SERVICE™
The ALFA LAVAL Salinometer DS-20 is a highly reliable marine salinity monitoring system designed to continuously measure and monitor salt concentration levels in boiler water, condensate return systems, and fresh water production plants onboard ships.
Maintaining proper water quality is critical for marine boilers, steam systems, and freshwater generation equipment. Even small amounts of salt contamination can lead to scaling, corrosion, reduced heat transfer efficiency, and costly machinery damage. The Salinometer DS-20 provides continuous monitoring and alarm functions that allow engineering personnel to detect contamination before serious damage occurs.
Widely installed on commercial vessels worldwide, the DS-20 has become a trusted solution for maintaining water purity and ensuring safe operation of boilers and freshwater systems.

PRODUCT OVERVIEW
The Salinometer DS-20 operates by measuring the electrical conductivity of water. Since dissolved salts increase conductivity, the system can accurately determine contamination levels and trigger alarms when preset thresholds are exceeded.
The equipment is commonly installed in:
- Marine Auxiliary Boilers
- Exhaust Gas Boilers
- Steam Condensate Systems
- Fresh Water Generators
- Distilled Water Systems
- Feed Water Monitoring Systems
- Engine Room Water Treatment Systems
The system continuously monitors water quality and provides visual indications of salinity levels in parts per million (PPM). If contamination rises above acceptable limits, the DS-20 activates alarms, allowing immediate corrective action.
This helps prevent:
- Boiler Tube Corrosion
- Steam System Contamination
- Scaling Formation
- Fresh Water Quality Problems
- Heat Exchanger Damage
- Costly Machinery Repairs
