subject: How Density Meters Are Used In Different Industries [print this page] Density meters are used to measure density with the use of a hydrometer and a drop of warm oil. The measurement of most oils in a density meter is at 50 degree Celsius although oils with very high viscosity may be set to warm temperature at 70 degrees Celsius. Density meters have a calculator option, which enables you to adjust the reading of the density. The calculator will show the anticipated combustion performance or CCAI, if the viscosity is read in Centipoise or Centistokes.
They are typically suitable for residual fuel and diesel oils. It uses hydrometers for measuring the marine fuel density. Given the fuel's viscosity, a density meter can identify the fuel mass delivered, calorie value and the CCAI. It is used to confirm the fuel quantity delivered, the fuel grade already delivered, the combustion performance and viscosity.
Density meters may be bought as stand-alone kits, as part of testing equipment in lube oil and fuel testing or supplied in own case. Results of a density meters has been found to be just as accurate as laboratory techniques.
Keep in mind that a density meter should not be used for heating any kind of liquid except for residual fuel oil or diesel. It should not be used with any kind of fuel with a temperature that has a low flash point, an example of which is gasoline.
When choosing density meters, there are important considerations that you need to keep in mind. For one, requirements for monitoring oil condition and online machinery are getting more and more apparent following the increase in maintenance costs, production capacity and maximization of equipment performance.
Given that pressure, temperature and vibrations sensors all play a part in playing the role of monitoring condition, other factors that you need to consider with regard to the actual condition of the machinery and equipment include regular monitoring of lubricant and oil condition as well as metal debris in order to detect whatever changes there may be.
The use of density meters have grown increasingly over time. Because of it's ability to measure and control liquid continuously, it helps to assure the quality of the product at the same time promote cost-effective measures in terms of getting rid of testing and sampling applications, among which include sludge settling to very corrosive substances in petrochemical industries; alkaline solution and acid concentration and mineral oil density.
Density meters also apply the measurement principle, which is taken from a single oscillating component, allowing for the elimination of seals within a reference chamber made of stainless steel and charged with gas. This type of construction does great wonders in terms of repeatability, which enables measurement to wider steams and temperatures having a significant reduction in viscosity and vibration errors. Sensors, which meet CIP needs and are also self-draining, re independently measured of position and orientation and also have a quick response to changes in liquid temperature.
