Mechanical diesel flow meter is a volumetric meter for continuous or intermittent measurement and control of diesel or other liquid flow in pipelines. It has many advantages such as large measuring range, high accuracy, small pressure loss, strong viscosity adaptability, ability to measure high temperature and high viscosity liquid (diesel), convenient calibration, and installation suggestions. It is suitable for flow measurement in petroleum, chemical, chemical fiber, transportation, commerce, food, medicine and health departments.

Characteristics of Diesel Flow

Diesel is a kind of light petroleum, which belongs to the fuel of diesel engine. The use of high-speed diesel engines on cars is more fuel-efficient than gasoline engines.

Diesel demand is growing faster than gasoline. Diesel engines have higher thermal efficiency and higher power than gasoline engines. The fuel consumption per unit is low and relatively economical, so the application is increasing day by day. In many occasions, it needs to be measured.

For oil tanker or diesel storage tank pipeline transportation, it is more suitable to choose a flowmeter with higher measurement accuracy. Because it is not only convenient for trade settlement, but also high precision. The measurement is accurate and can be used for a long time.

According to the role of diesel: the use can be divided into marine diesel engine, locomotive diesel engine, automobile diesel engine, power generation diesel engine, agricultural diesel engine, construction machinery diesel engine, etc.

Diesel Fuel: Diesel fuel is primarily diesel. Light diesel oil is usually used for high-speed diesel engines. Light diesel or heavy diesel for medium and low speed diesel engines.

Mechanical Diesel Flow Meter Working Principle

Oval gear flow meters are our most commonly used Mechanical Diesel Flow Meters.

The oval gear flowmeter is composed of a metering box and a pair of elliptical gears installed in the metering box, and the upper and lower cover plates form a sealed crescent-shaped cavity (due to the rotation of the gear, it is not sealed) as the calculation unit of a displacement .

The flow meter is mainly composed of a housing, a counter, an elliptical gear, and a coupling (magnetic coupling and axial coupling), etc. As shown in the figure.

Structure and working principle of Oval Gear Flow Meter

1.Counter 2. Transmitter

3. Accuracy adjuster (used above DN50)

4. Sealed coupling

5. Front cover 6. Cover plate

7. Oval gear 8. Shell

9. Rear cover

When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet pushes a pair of gears to continuously rotate, and the liquid measured by the crescent-shaped cavity is continuously transported to the outlet. The product of four times the secondary displacement is the total amount of the measured liquid flow.

The elliptical gear generates a torque to make it rotate under the action of the pressure difference △p of the measured medium.

The rotor 1 and the rotor 2 are alternately driven by one to rotate the other. There are two magnets on each rotor as signal generating elements. There is a magnetic signal detecting element at the center of the two axes at the bottom of the cavity. Whenever the magnet turns to the detecting element, the sensor counts as a pulse.

Each pulse corresponds to a certain amount of medium discharge F, F=XXml/p, so the volume flow Qm per unit time can be obtained: Qm=F*H, F is the amount of medium removed by each pulse; H pulse per unit time number.

Advantages of Oval Gear Mechanical Diesel Flow Meters

  • High measurement accuracy: 0.2 and 0.5;
  • The mechanism is simple, firm and reliable;
  • Especially suitable for measuring medium with high viscosity. And it is not sensitive to changes in the viscosity of the liquid being measured;
  • Easy to install. No straight pipe sections are required before and after the flowmeter. Even if the flowmeter is close to valves, elbows, shrinks, and expansions, there is no need to add straight pipe sections.
  • In order to prevent the gear of the flowmeter from being stuck by impurities. A filter must be installed upstream of the flow meter

It is a type of flowmeter, and the measurement component is a purely mechanical structure, which is a mechanical flowmeter. Such as oval gear flowmeter.

Take an oval gear flowmeter as an example. Under the action of fluid flow, a pressure difference is formed between the inlet and outlet of the instrument. A pair of oval gears are constantly rotating on the shaft. The cavity between its gears is filled with liquid.

As the rotation is discharged, the flow rate of the liquid flowing through the meter can be known by measuring the number of revolutions of the oval gear.
Assume that the volume of the oval gear discharged by one rotation of the oval gear is Q. The number of rotations of the oval gear per unit time is N. Then the volume of liquid that flows during this time is NQ.

Commonly used fuel flowmeters include turbine flowmeters, circular gear flowmeters, oval gear flowmeters, mass flowmeters, etc.

Industrial oil flow meters measure the volume or mass of oil. Can realize the mutual conversion of volume and mass.

The main industrial oils are hydraulic oil. Gear Oil. Turbine oil. Compressor oil. Refrigeration oil. Transformer oil. Cylinder oil, heat treatment oil, heat transfer oil, etc. Of course, edible oil can also be produced in the industry. In addition, there are greases with lubricating oil as base oil and thickening agent.

Therefore, whether it is a company that uses, trades, or produces oil, it needs to accurately measure the oil flow.

There are many common oil flow meters, such as turbine flow meters, positive displacement flow meters, gear flow meters, mass flow meters, etc.
