What kind of flow meter is used to measure lubricating oil?

Project Overview

When choosing a lubricating oil flow meter, the following factors are usually considered:

1. Viscosity range : Lubricants come in a wide range of viscosities, from thinner lubricants to thicker lubricants. The flow meter needs to be able to accommodate the viscosity range of the lubricant being measured.

   

2. Flow range: Determine the flow range of the lubricating oil that needs to be measured. Some applications require the measurement of very small flows, while other applications require the measurement of large flows.

3. Precision and Accuracy: Choose the appropriate level of accuracy based on application needs. Some applications may require high-accuracy measurements, while others may accept relatively low accuracy.

4. Pressure and Temperature: Consider the required operating pressure and temperature range of the flowmeter to ensure that the chosen flowmeter can operate reliably under these conditions.

   

Generally speaking, common types of instruments used to measure lubricating oil flow include vortex flowmeters, gear flowmeters, balance flowmeters, etc. Therefore, the balanced flow meter can naturally be used in the medium of lubricating oil.

For example, the working pressure of lubricating oil in a DN65 diameter pipe is about 1.0MPa, the working temperature is normal temperature, the working flow is 0~850L/min, the pipe material is carbon steel, and flange connection is to be used. Flange standard: GB/T 40PL-DN65, RF. You can use the balanced flowmeter model DQP65CF11456A, and according to user feedback, the measurement accuracy is still very high after using it for two years.
