Common Industrial Fuel

Fuel oil refers to light distillate fuel oil and heavy distillate fuel oil obtained after crude oil is distilled and processed in a refinery. The former mainly includes gasoline, diesel and jet fuel used in crawling machinery and aircraft internal combustion engines. The latter is mainly used as boiler fuel for steam furnaces and various heating furnaces.

Fuel oil is a fuel used for engine operation, mainly divided into gasoline and diesel.

There are two main types of fuel for automobiles, gasoline and diesel.

The aircraft uses aviation kerosene.

The classification of gasoline is based on the octane number it contains, such as 90#, 97#, etc. The higher the octane number, the lower the probability of deflagration produced by the car, and the better it is for the engine. Therefore, most high-end cars use higher-grade gasoline.

The classification of diesel is based on its freezing point. 0# means that when the temperature is lower than 0 degrees Celsius, it will condense into a solid. The same reason -10# means that it condenses into a solid at -10 degrees Celsius. This is the reason why the diesel cars in the northern winter have a lower label to prevent the fuel from being frozen.

Fuel flow meter for diesel

Fuel flow meter for diesel

Three kinds of flow meters are commonly used to measure diesel:
The first is an oval gear flow meter, which is also commonly used, with an accuracy of 0.5.
The second type is liquid turbine flowmeter, the accuracy can be 0.5 or 0.2, flange or thread connection
The third type is float type, installed vertically or horizontally, with an accuracy of 1.5.

Although they all measure the flow of diesel oil products, the difference is still very large.

For example, dual-rotor flowmeters and oval gear flowmeters can measure diesel fuel. And various parameters are in line with the measurement range of these two flowmeters.

However, the measurement range of the dual-rotor flowmeter is very large and the noise is very low, and the accuracy is also high. Under the conditions of high precision and low precision, the liquid flow range is very large. However, the minimum pipe diameter is 25mm and the maximum is 300mm;

The oval gear flowmeter is different. The minimum pipe diameter is 6mm and the maximum is 200mm.

And the flow range is very wide. The most important thing is that the price is relatively cheap, which is the best choice for most customers.

How does micro motion flow meter work?

The micro-motion mass flowmeter is a flowmeter made according to the Coriolis acceleration theory. There is a straight tube that rotates in a plane around a fixed axis O at an angular velocity w, and a particle in the tube moves outwards along the straight tube at a speed v. Because The mass point m is in a system with both rotational motion and linear motion, so it will obtain two accelerations.

Serving size:

① Centripetal acceleration a, its value is rw^2 (r is the distance from the particle m to the axis O), and the direction points to the axis O.
② Tangential acceleration ac, its value is 2uw. The direction is perpendicular to a, it comes from the rotating pipe. At the same time it produces a reaction force to the pipe. This reaction force is the Coriolis force. Its calculation formula is:

F=2muw —————-(3-8)

Where:
F is Coriolis force, N;
w is the angular velocity, 1/s;
u is the radial velocity in the rotating system, m/s,
m is the mass of the moving object, kg.

If the density of the fluid is p, the tangential Coriolis force on any section of pipe △x is:

△F=2pA△xuw ———(3~9)

Where:
A is the cross-sectional area of ​​the pipe.

In the formula (3-9), pAu is the natural flow rate of the fluid, set as QM’, then the formula (3-9) can be expressed as:

△F= 2w△xQm————-(3-10)

From the above equation, we can know the mass flow Qm as long as the Coriolis force △F is measured. This is the measuring principle of micro-motion mass flowmeter.

How to choose a Hydrogen flow meter? Hydrogen is a valuable and widely measured industrial gas. Custody transfer metering is a very important feature of hydrogen flow measurement.

Common gas flow meters include thermal mass flow meters, vortex flow meters, precession vortex flow meters, and gas ultrasonic flow meters. How to select a hydrogen flow meter? Next, we will discuss in detail.

Characteristics of hydrogen

Hydrogen (chemical formula H2) consists of two hydrogen atoms, which is colorless, tasteless, odorless, non-toxic, and flammable. With a molecular weight of 2, and a specific gravity of 0.0695, hydrogen is considered the lightest gas, more than 14 times lighter than air (mv=28.8).

Hydrogen is very flammable. Under normal pressure, a mixture with a hydrogen content of 4.0% to 74% can be flammable. Since the minimum ignition energy of hydrogen (0.02mJ—one order of magnitude smaller than the minimum ignition energy of hydrocarbons) is very small, strict precautions must be taken to prevent leakage.

The most preferred hydrogen flow meter

Thermal Mass Flow Meter can directly measure the mass flow of various gases. Unaffected by changes in viscosity, density, temperature, or pressure.

Thermal Mass Flow Meter is a true mass flow meter. No temperature and pressure compensation is required. Thermal gas mass flow meters are designed based on the principle of thermal diffusion. Including natural gas, coal gas, liquefied gas, flare gas, argon, carbon dioxide and other mixed gas flow measurement.

Mass flow measurement of hydrogen

At present, the Coriolis mass flowmeter and thermal gas mass flowmeter are the most reliable and the most reliable hydrogen flow measurement applications. Both of these are flow meters for direct mass flow measurement, and neither have movable parts and have a large range. The fluid contact surface is made of 316L, which improves the durability and safety of field application.

The sensors of Coriolis mass flowmeter and thermal gas mass flowmeter are all welded. Because the pressure sensor interface and temperature sensor are not required to correct the flow reading to the volume flow under the standard state. Therefore, the system pipe joint used Be reduced to a minimum.

The sensor connection method has flange connection, flange to clamp connection, thermal gas mass flowmeter can also provide large pipeline plug-in connection.

Coriolis mass flowmeters and thermal gas mass flowmeters can provide up to 0.5% accuracy due to their excellent detection technology, which has huge advantages in trade settlement and measurement.

These two types of flow meters have advanced measurement technology, good long-term application stability, and extremely low on-site maintenance costs. They are very popular measuring instruments.

The shortcomings of Coriolis mass flow meters: large pipe diameters are bulky, inconvenient to install, and extremely expensive to purchase. It is inferior to the thermal gas mass flowmeter in the small flow measurement characteristics.

Disadvantages of thermal gas mass flow meters: the high flow rate range is not as good as Coriolis mass flow meters. In order to accurately measure the hydrogen flow rate, it is necessary to use real flow calibration for the flow meter calibration.

Hot Water Flow Meters Improve Heating-Boiler System

Hot water flow meters refer to flow meters that can measure and indicate the flow of high temperature water. Hot water is widely used in industry and civil use. Such as heating systems, baths, boilers, industrial indirect heating, heat transfer, etc. There are many types of water flow meters. Some of the most common types include electromagnetic flow meters, turbine flow meters, and vortex flow meters. These meter types have unique features that distinguish them from each other. According to the function of the hot water flow transmitter and the user’s budget. You can choose a suitable flow meter to monitor the hot water pipeline.

Features of Hot Water Flow Measurement

What are the characteristics of hot water flow measurement? Let’s take a look.

1. The temperature of the measured fluid is not very high. When the flow meter is installed at the entrance of the heat exchanger body. The temperature of the fluid is generally not higher than 140°C. When the liquid outlet of the heat exchanger is installed, the flow temperature is lower.
2. The measured fluid pressure is not very good either. In order to send hot water to the highest floor in the building heating system, the pressure is sometimes higher. In the ground heating system, the highest pressure is 1MPa.
3. The pipe diameters vary in size. The smallest user, the pipe diameter is only DN20~DN40. The large-diameter flowmeter sometimes reaches about 1m.
4. Better cleanliness. Hot water is not as clean as tap water. The solid matter in the single water and its viscosity will not have a big impact on the general flowmeter.
5. Corrosive. Fresh water does not corrode the flowmeter. However, geothermal water has a certain degree of corrosion. Because it contains chloride ions and so on. Ordinary stainless steel materials are corroded, and the higher the fluid temperature, the more severe the corrosion.
6. The requirement for scope is not high. The pumps used in power plants (stations) to deliver hot water are generally combined in size. When the hot water supply is at its maximum, usually several large pumps are opened. When the heat supply is the smallest, generally only a small pump is turned on. The ratio of the maximum flow rate to the minimum flow rate is about 5~10. A flow meter for heat measurement of a single user. In the heating season, the flow measurement range of up to 10 can meet the demand. After the hot water valve is turned off, the market value of the flow should be 0.

Hot Water Flow Meter with Pulse Output

Commonly used flow meters have three forms: current output, voltage output, and pulse output.

Among them, the current output and the voltage output signal of the instrument are in line with the International Electrotechnical Commission (IEC) standard. There is currently no standard for the pulse output signal of the instrument.

The flowmeter with pulse output, its output is a pulse signal proportional to the flow rate. Compared with the analog signal of voltage and current, the pulse signal is convenient for remote transmission without reducing the accuracy, and there is no zero drift. It is easy to connect with the computer, easy to carry out cumulative display and has a strong anti-interference ability.
