Ferrous Wear Meter

Ferrous Wear Meter (FWM)

A device to determine if there are metal particles in oil samples from lubricated machinery. This device is the optimal solution for taking oil tests on-site, on board or in remote locations where you don't have access to a laboratory.

The FWM is:

  • Simple
  • Accurate
  • Easy to use.

Prevent breakdown and plan your maintenance 

With the Ferrous Wear Meter from Parker Kittiwake, you can equip your vessel with a strong and incredibly simple tool for breakdown prevention and wear monitoring of all lubricated parts on board.

Designed specifically for use by crew on board, the Ferrous Wear Meter is ideal to monitor the wear on:

  • Engines
  • Gear boxes
  • Bearings.

Main advantages and benefits: 

  • Appropriate for use on-site, on board and in remote locations
  • Very simple and easy to use
  • With LCD screen to give PPM
  • Reduced Operating Costs
  • Decreased Downtime
  • Reduced Scrape Down Oil Usage
  • Immediate ferrous wear measurement in PPM on the LCD screen.

Perform the test in less than 2 seconds

To do the test just do the following:

  1. Take a tube with 5 ml of sample oil
  2. Put it in the hole in the unit
  3. It's metallic content in PPM will display on the LCD screen in less than 2 sec.

Base your maintenance decisions on data 

By performing an analysis on a sample of lube oil, the Ferrous Wear Meter detects the content of ferrous debris from abrasive wear in moving parts. With sample as small as 5 ml, the instrument utilizes a magnetic principle to determine the amount of debris in the lube oil. By doing the analysis frequently with fixed intervals, an increase in wear can be detected at an early stage. This will allow the crew to base their maintenance on the actual conditions of the equipment, rather than on conservatively recommended service intervals.

Easy operation that everyone can do 

The test itself could not be more straight forward or simple. A sample is draw from the equipment you wish to analyze and is put into one of the disposable test tubes that comes with the analyzer. The Ferrous Wear Meter just need to be powered up, and once it is ready for use, the test tube is inserted into the test tube slot. In a matter of seconds, the instrument will display a reading, showing the content of ferrous material in ppm.

Cleaning and maintenance

Like any other device, machinery, or item on board of your vessel, keeping the Ferrous Wear Meter clean and upholding the general maintenance of the device will extend the lifetime of the FWM.

When cleaning the instrument, you should use a soft cloth and only a mild detergent. The usage of other solvents or cleaning products on the FWM might cause damage to the device.

The measurement hole of the instrument (see picture below) is very important to keep clean all the time, as test data will be variable and inaccurate if not. This hole can also carefully be cleaned with a soft cloth and mild detergent like the rest of the FWM.

Furthermore, the Ferrous Wear Meter have no user serviceable parts. Which makes it easier for you to only focus on the basic, but necessary cleaning. However, do not disassemble the FWM! If you do, the warranty will be invalid if the FWM is disassembled.

Positioning of the FWM

The instrument should be located according to the following guidelines:

Find a flat, level surface as for example a workbench or a desk and set up the FWM here

Keep the instrument in a temperature stable environment for the best results. Thus, away from strong drafts and heat sources such as air conditioning vents or heaters

If you have strong magnetic fields avoid placing the FWM in near proximity to this. For example, large electronic motors or generators, power transformers, loudspeakers, or microwave ovens. These devices create such strong magnetic fields sometimes that the device can be affected even through walls.

How to take a sample

Here is a step-by-step guide for you to take a sample:

  • Shut the main drain valve (see 1 in picture)
  • Open the sampling valve very carefully (see 2 in picture) and purge into a suitable container (the oil will be disposed of later)
  • Remember to close the sampling valve (see 2 in picture) after purging
  • Keep the main valve closed (see 1 in picture), while you allow liquid to build up in the drain line (see 3 in picture)
  • Take the sample bottle and place it under the sampling line (see 4 in picture)
  • Open the sampling valve very carefully (see 2 in picture) and collect your sample. At the same time you should collect enough additional material to check for example corrosive wear with the Cold Corrosion Test Kit (FG-K19875-KW).
  • Close the sampling valve (see 2 in picture) and re-open the main drain valve (see 1 in picture) or reset to the correct running position of your need.

Scrape Down Oil Analysis (SDA)

Are you worried about abrasive wear or water in your cylinder/ lube oil?

The non-stop financial pressure on you makes the drive to safe money apply not only to fuel savings, but also to cylinder lubrication oil.

Thus, the Ferrous Wear Meter can be used to feed rate optimization of cylinder scrape down feed rates on-board vessels, which allows you to save in your oil use. Furthermore, you can be sure that catastrophic cylinder damage is happening to the liner and/pr ring packs due to less lubrication of the cylinder bore.

As you know, the drive to save operating costs has, moreover, led vessels to operate under slow steaming conditions, as you run the vessel at lower speeds and engine powers. This is leading to issues with cylinders, where corrosive wear appears, also known as cold corrosion.

You can get the full picture of your cylinder operating conditions, when using the Ferrous Wear Meter together with the Cold Corrosion Test Kit (FG-K30377-KW), as well as Base Number (BN) Testing done with the DIGI TBN Test Kit (FG-K1-004-KW).

Cold Corrosion Test Kit (FG-K19763-KW)

The Cold Corrosion Test Kit is a good way to accurately analyze the level of corrosive elements in cylinder oil, which can prevent serious damage.

Within 5 minutes you will know the non-metallic iron concentration in the scrape down oil. Thus, it is a quick and simple on-board test, where you avoid sending the sample to a laboratory.
