2、 Measurement principle of lubricating oil flowmeter

Under the action of the pressure difference between the liquid at the inlet and outlet of the flowmeter measurement chamber, a pair of elliptical gears continuously rotate on the bearings and discharge the liquid. By measuring the number of revolutions of the elliptical gears, the total value of the liquid flowing through the instrument can be determined. If the volume Q discharged after one revolution of the elliptical gear and the number of rotations of the elliptical gear per unit time is N, then the volume of liquid flowing through during that time is NQ.

3、 Characteristics of Lubricating Oil Flow Meter Products

The lubricating oil flowmeter installed correctly according to the requirements can ensure sufficient accuracy during use, and the accuracy of the cumulative value can usually reach level 0.5, making it a relatively accurate flow measuring instrument. However, if the flow rate of the measured medium is too high during use.

Small, the impact of instrument leakage errors will become prominent, and sufficient measurement accuracy cannot be guaranteed. Therefore, diesel flow meters of different models and specifications have an allowable value for * * * small flow rate. Only when the actual measured flow rate is greater than the lower limit flow rate allowable value, can the measurement accuracy be guaranteed.

Secondly, when using a lubricating oil flowmeter, it is important to note that the temperature of the measured medium should not be too high, otherwise it will not only increase measurement errors but also have the potential to cause gear jamming. Therefore, the oil flow meter is used within the temperature range specified by the instrument.

LAGear flowmeter (circular gear flowmeter)

overview

It is a new type of volumetric flowmeter, also known as a Fuda flowmeter, used for precise continuous or intermittent measurement of liquid flow or instantaneous flow in pipelines. It is suitable for flow measurement of high viscosity media such as heavy oil, polyvinyl alcohol, and resin, and can accurately measure small flow rates.

Working principle and structure

There is a pair of gears that mesh with each other inside the flowmeter chamber as rotors. The two gears and the chamber can form a fixed volume, which is called the standard volume. The flow rate is measured by calculating the number of flows through the standard volume over a certain period of time.

Schematic diagram of gear flowmeter structure

characteristic

Flow measurement is independent of the flow state of the fluid;

The higher the viscosity of the medium, the smaller the amount of leakage from the gear and measuring space gap. Therefore, the higher the viscosity of the measured medium, the smaller the leakage error, which is more beneficial for measurement.

The gear flowmeter has high measurement accuracy and is suitable for high viscosity medium flow and measurement, but it is not suitable for fluids containing solid particles and requires the installation of filters. If gas is mixed in the medium, it can also cause measurement errors.

L has a small volume, light weight, and low vibration noise during operation, and can measure fluids with viscosity up to 10000 pa. s. The measurement accuracy is level 0.5 and level 0.2. The measurement range is wide * * * and the height can reach 50:1

There are various types such as universal, high-pressure, and food grade, suitable for measuring small flow rates of various cleaning liquids.
