UNDERSTANDING THE DIFFERENCE

Water Cut Meters Vs. Water-in-Oil Monitors

Both detect water contamination in hydrocarbons, but operate at opposite ends of the measurement scale and serve different industrial functions

Learn More

Water Cut Meters

Water Cut Meters measure high volumes of water (typically 0% to 100%) mixed with oil. They are primarily used in production and custody transfer.

Water-in-Oil Monitors

Water-in-Oil Monitors measure small amounts of water (typically in low ranges). They are primarily used for machinery protection and quality assurance.

INDUSTRY APPLICATIONS

Trusted Across Critical Industries
Upstream Oil & Gas
(Wellheads & Separation)
This is the most common home for high-capacity water cut meters. When oil is pumped from a reservoir, it is naturally mixed with a significant amount of formation water.

Well Testing:
Installed directly at the wellhead or on test manifolds to track how much water an individual well is producing. This helps reservoir engineers evaluate well performance and detect early "water breakthrough". 

Production Separators:
Placed on the oil discharge leg of 2-phase or 3-phase production separators to verify that the separation equipment has successfully stripped the bulk water out of the crude stream before it enters a transport pipeline. 
Midstream Oil & Gas
(Pipelines & Custody Transfer)
In the midstream sector, minimizing water is a matter of financial accuracy and pipeline integrity.

LACT Units & Custody Transfer Skids:
When crude oil changes ownership (e.g., from a producer to a pipeline operator or onto a tanker ship), buyers use water cut meters to measure BS&W (Base Sediment and Water). Buyers only want to pay for the net oil, not the water.  

Pipeline Corrosion Control:
Water trapped in crude pipelines causes internal pipe corrosion and can lead to the formation of gas hydrates. Continuous monitoring alerts operators to drop water out before it ruins midstream infrastructure.
Marine Engineering & Shipping
Onboard ocean-going vessels, oil tankers, and submarines, water-in-oil monitors act as critical safety switches to prevent catastrophic mechanical failures.

Main Engine & Propulsion Lubrication:
Large marine diesel engines and thrusters rely on massive oil sumps. If a heat exchanger leaks seawater into the engine lube oil, it can wipe out bearings. Inline sensors monitor the oil loops in real time to trigger alarms before the oil loses its lubricity.  

Fuel Purifiers & Centrifuges:
Ships burn heavy fuel oil (HFO) or marine diesel, which must be run through high-speed centrifugal purifiers to remove water before it hits the injection system. Monitors are installed on the purifier outlets to ensure the fuel is bone-dry.
Power Generation
(Turbines)
Power plants rely on massive, rotating machinery that cannot tolerate water ingress.

Steam & Gas Turbine Lubrication:
Water can sneak into turbine oil via steam gland seal leaks or cooling systems. Continuous trace monitors ensure the turbine bearings stay flooded with pure oil, preventing unexpected power plant trips.
Heavy Manufacturing & Industrial Hydraulics
High-pressure hydraulic lines and high-speed industrial gearboxes are highly sensitive to moisture. Engine protection systems requiring continuous monitoring of water in oil or fuel.

Hydraulic Power Packs:
In steel mills, paper mills, and injection molding facilities, water contamination in hydraulic oil degrades the fluid, destroys precision valves, and causes pump cavitation.

Industrial Dehydration Systems:
Used on the outlets of oil filtration skids or vacuum dehydrators to verify that the recycling system has successfully removed moisture from reclaimed industrial oils.

Product Range

Water-cut Analyzers

The EASZ-1 Water-Cut Monitor is a reliable online instrument that has been in use for more than a decade. It is a low powered 2-wire solution for water in oil measurements. Suitable for offshore and onshore environments with simplified zero calibration on dry oil with the press of a button. Percentage calibration using RS-232 or HART.

Water in Oil Monitors

The EASZ-2 LR is an “Easy 2 Use” online instrument that is far more accurate and repeatable than it’s predecessors. It has been designed to faithfully maintain accuracy and repeatability in industrial environments without compromising precision, especially in lower concentrations of water…

 

0-100% Full-cut

Online cut measurements of oil in water or water in oil. Communication through RS-485 Modbus with 4-20 mA output, low/ high alarm. Bluetooth for easy set-up and calibration in an oil field. A modern solution to an age old application. The multi-point calibration system allows users to improve the accuracy across the full range of 0-100%.

Water in Oil Monitors

The EASZ-1 and EASZ-2 are original products designed and manufactured by EESIFLO®. EASZ inline sensors display and transmit actual water content in crude oil pipelines, petroleum, lubrication, hydraulic systems and vegetable oils. The products are designed for general purpose measurement of water content in oil and in Ex versions for the oil and gas industry where these products are often referred to as watercut meters and BS&W probes which are used in oil separation units, LACT systems and crude oil metering stations.
