Why do Water in Oil Monitors go under different names?
Online Water-in-Oil Sensors are essential for detecting and monitoring water contamination in oil and fuel systems. However, depending on the industry or application, these instruments are often referred to by different names.
Why So Many Different Names?
Online Water in Oil Sensors are often given different names. Sometimes they are referred to as water sensors, water-cut analyzers, bs&w probes, moisture sensors and moisture meters. The name given to the product often depends on which industry is using them and what terms they are familiar with. Some operators also use the EASZ products for detecting water in fuel lines.
Is It Moisture or Is It Water?
The answer to this may not be so clear when considering that some chemicals are designed to be either hydrophilic or hydrophobic. We are measuring small or large changes in the dielectric constant of a liquid. The instrument will detect changes in H2O content, whether the H2O in oil is dissolved, emulsified or free.
The video above shows a typical application where the instrument is referred to as a ‘moisture in oil meter.’ At the beginning of the video, however, it is actually detecting a change in the free water content during tank truck unloading
What is an Online Water in Oil Monitor?
An online water in oil monitor or water sensor measures everything that passes through a process pipe. An offline instrument determines the water content of an oil by measuring a small volume (spot sample) in a laboratory e.g. centrifuges, karl fischer etc.
Why Online Monitoring is Important
- Water contamination in oil can cause corrosion, oil degradation, equipment failure, and costly downtime. Relying solely on spot sampling may leave operators blind to water events that occur between tests.
What are the benefits of continually monitoring oil and fuel?
Spot sampling for water in oil is not able to capture every “water event.” A water event could simply be small clouds of water droplets travelling down a pipe but never detected by a typical moisture sensor. Our water in oil monitors will not only give an indication of the dissolved water in oil but also capture events e.g. free water.
With an online water-in-oil monitor, operators benefit from:
Early detection of water ingress from condensation, cooler leaks, or process faults.
Continuous protection of engines, turbines, compressors, and pipelines.
Improved efficiency by reducing the need for frequent manual sampling.
Reliable compliance with quality and safety standards.
Selecting the Correct Water in Oil Monitor
General Industry
These versions of our products do not require Ex Certification and are installed in non-hazardous areas. The standard connections are normally either screwed connections e.g. NPT, BSP, or flanged units to ANSI, DIN, JIS. Other connections are also available e.g. SAE for hydraulic oil and sanitary connections for the food and drink industry.
