Aqua Sensor for Hydraulic Oil & Lubrication Systems
In hydraulic and lubrication systems, even small amounts of water can cause oil acidification, corrosion, and performance loss. Early detection and removal are crucial to avoid system failures, downtime, and costly repairs. Our Aqua Sensor provides a reliable way to monitor and manage water contamination in oil, ensuring smooth operation and longer equipment life.
How Aqua Sensors Measure Water in Oil
The two common methods are:
- PPM (Parts Per Million) – widely used but limited as it doesn't account for oil temperature changes.
- Saturation Level (%) – adjusts for temperature variations, providing a more accurate and reliable reading.
Our advanced Aqua Sensor measures dissolved water content online, in real time, as a saturation percentage. It works independently of oil type, age, and temperature:
- 0% = water-free oil
- 100% = fully saturated oil
Benefits of Using Aqua Sensors
- Continuous real-time monitoring of water contamination
- Prevents oil acidification and corrosion of system components
- Ensures longer oil life and reduced maintenance costs
- Independent of oil type, age, or temperature
- Improves system reliability and reduces downtime
With our Aqua Sensor, you can effectively monitor and control water content in oil, ensuring maximum system reliability, lower costs, and extended equipment lifespan.

FAQ'S
Oil Filtration & Contamination Sensors are advanced monitoring and filtration devices used in hydraulic and lubrication systems to detect, measure and remove oil contamination in real time. They help maintain ISO 4406, NAS 1638 and AS 4059E cleanliness standards, preventing costly hydraulic system failures and component damage.
Oil contamination is the leading cause of hydraulic system failures — responsible for nearly 80% of all breakdowns. Contaminated oil causes accelerated component wear, increased downtime, reduced system efficiency and costly repairs. Early detection using oil contamination sensors helps prevent these issues before they become critical.
Techknow Engineering offers three types of oil filtration units — Portable Oil Filtration Units, Mobile Oil Filtration Units and Electrostatic Oil Filtration Units — along with Low Vacuum Dehydration Units for water and dissolved gas removal from hydraulic and lubrication oils.
ISO 4406 measures particle contamination in three size ranges (4µm, 6µm and 14µm) and assigns a cleanliness code, while NAS 1638 classifies contamination into classes 00 to 12 based on particle count per 100ml. Both standards are used globally to define and maintain hydraulic oil cleanliness levels.
An In-line Oil Particle Counter uses advanced LED-based Light Extinction Automatic Optical Monitor Technology to measure and display ISO/NAS cleanliness levels in real time. It continuously monitors oil flowing through the hydraulic system and alerts operators when contamination levels exceed acceptable limits.
An Aqua Sensor measures dissolved water content in hydraulic and lubrication oil in real time as a saturation percentage — from 0% (water-free) to 100% (fully saturated). Even small amounts of water in oil can cause acidification, corrosion and performance loss, making early water detection critical for system protection.
Oil Filtration & Contamination Sensors can be installed in hydraulic power units, gearboxes, compressors, turbines, lubrication circuits and any industrial machinery where oil cleanliness is critical. They are widely used across oil & gas, power generation, marine, manufacturing and heavy machinery industries.
