How to choose the right lubricating oil flow meter?
2024-10-12
Lubricating oil flow meter is an indispensable instrument in industrial equipment and machinery, which can accurately measure the flow of lubricating oil and help monitor abnormal conditions in equipment operation. When choosing the most suitable lubricating oil flowmeter equipment, you need to consider the following key factors:

1. Measure media characteristics
Viscosity range: Lubricants have a wide range of viscosity, ranging from thin to thick. The flow meter needs to be able to adapt to the viscosity range of the lubricating oil being measured to ensure the accuracy of the measurement. The elliptic gear flowmeter is especially suitable for measuring the flow of medium with high viscosity such as heavy oil, polyvinyl alcohol and resin.
Medium compatibility: The material of the flow meter should be compatible with the lubricating oil and the internal environment of the gear box to avoid corrosion or damage.
2. Flow range and accuracy
Flow range: According to the actual working needs of the gearbox, determine the lubricating oil flow range that needs to be measured. Some applications need to measure very small flows, while others may need to measure large flows.
Precision and accuracy: High precision measurement is especially important for precision equipment and critical processes. Select the appropriate level of accuracy according to the application requirements to ensure the reliability of the measurement results.
3. Working pressure and temperature
Consider the required operating pressure and temperature range of the flowmeter to ensure reliable operation in the gearbox operating environment. For example, the use temperature of the elliptic gear flowmeter should be within the temperature range specified by the instrument to avoid increasing the measurement error or causing the gear to stick.
4. Flowmeter type and characteristics
Elliptic gear flowmeter: It has the advantages of high measurement accuracy, small influence on liquid viscosity, and no need to install straight pipe section before the table. The working principle is that under the action of the liquid pressure difference at both ends of the instrument measuring chamber, a pair of elliptical gears constantly rotate on the bearing and discharge the liquid. By measuring the number of revolutions of the elliptical gear, the total volume of liquid flowing through the instrument can be calculated.
Balanced flowmeters: Designed with the balance principle of fluid dynamics in mind, they provide stable measurements over a wide flow range. It has good adaptability and accuracy for the measurement of lubricating oil and other media.
Vortex flowmeter: Calculate the flow rate by measuring the frequency of the vortex generated by the fluid in the pipe. Although vortex flowmeters are widely used in a variety of fluid measurements, they may be limited in the measurement of high-viscosity lubricants because their measurement accuracy is greatly affected by fluid viscosity.
Mass flowmeter: Calculate the flow rate by measuring the mass flow rate produced by the fluid as it flows through the sensor. Suitable for liquids and gases, high accuracy, but high cost.
5. Installation and maintenance
Installation method: Different types of flowmeters have different requirements for installation methods. For example, the electromagnetic oil flow meter needs to be installed in an environment without a magnetic field, and the vortex oil flow meter needs to be installed in a straight pipe section. Therefore, in the purchase to ensure that the selected flow meter can adapt to the actual installation environment.
Maintenance needs: The flow meter may suffer from corrosion and wear after long-term use, which affects the measurement accuracy. Therefore, the maintenance needs and replacement cycle of the flow meter should be considered in the purchase to ensure its long-term stable operation.
6. Brand and after-sales service
Brand selection: Choose a well-known, good reputation of the brand, you can ensure the quality of the flow meter and after-sales service. These brands usually have a more stringent quality control system and a more perfect after-sales service network, which can provide users with a better experience.
After-sales service: Understand the manufacturer's after-sales service and technical support. Choosing a manufacturer with perfect after-sales service and technical support can ensure the normal use and timely maintenance of the flow meter.
To sum up, the selection of the most suitable lubricating oil flowmeter equipment needs to consider the characteristics of the measuring medium, flow range and accuracy, working pressure and temperature, flowmeter type and characteristics, installation and maintenance, as well as brand and after-sales service and other factors. Through a comprehensive evaluation of these factors, you can choose the most suitable flowmeter equipment for your needs, providing a strong guarantee for the stable operation of the equipment.
