Factors affecting the accuracy of petroleum flow meters

(1) Instrument accuracy

During the production of the flow meter, due to rough parts, assembly accuracy and wear, etc., the accuracy of the flow meter itself is not high or the accuracy is reduced, so that the quantity of petroleum products sent (paid) is inaccurate. Therefore, when selecting a flowmeter, one with higher accuracy should be selected. At present, the accuracy of the working flowmeter is required to be ±0.5% in China, and the periodic verification should be carried out according to the regulations in use.

(2) Installation process

Although the accuracy of the flowmeter is high, due to improper or unreasonable installation process, the flowmeter will produce systematic errors. If there is not enough straight pipe section in front of the flowmeter (generally the straight pipe section should not be less than five times the diameter of the oil pipeline used), eddy current will occur, and the elbow in the pipeline will increase the flow resistance for a long time, which cannot guarantee the working pressure of the flowmeter. It can cause errors in the indication value of the flowmeter.

(3) Medium

The medium used for the factory calibration indication value of the flowmeter is different from the medium at work, and the indication value reflected by the flowmeter is also different. For example, water is used as the medium during calibration, but it is used in various petroleum product media during work, so there will be errors, mainly due to the different viscosity of the medium. Therefore, it is required that the medium used for calibrating the indication value of the flowmeter should be consistent with the working medium, so as to eliminate the error caused by this.

(4) Temperature

The flowmeter cannot display the true value of the output (payment) amount due to accidental errors caused by temperature instability during the work start to end. Therefore, it is required that the flowmeter should keep the temperature as consistent as possible during the oil delivery process.

(5) Differential pressure and flow rate

The use of the flowmeter should be within the specified pressure differential range to ensure accuracy. Because the pressure is high and the flow rate is fast, the flow rate is also large, and vice versa. If the flowmeter cannot maintain the consistency of the pressure difference between the front and rear during the oil delivery process, and it is higher or lower than the working pressure difference range of the instrument, it will affect the accuracy of its output (payment) volume.

(6) The working environment is different from the verification environment

During the periodic verification of the flowmeter, if it is carried out in a specific device of the metrological verification unit, when it cannot be consistent with the verification conditions in use, environmental errors will also occur. Therefore, when periodic verification is required, it is required to be carried out under working conditions, that is, on-site calibration.

Flowmeter selection principle

The rational design and selection of flow meter should be a scheme with high reliability, convenient maintenance and cost saving under the premise of meeting the requirements of use.

The factors that need to be considered in the selection of flow meters mainly include: fluid characteristics, flowmeter characteristics requirements, installation conditions, environmental conditions and costs.

In addition, the selection of flow meters cannot fully pursue high performance and high precision, which not only increases the procurement cost, but also increases the cost of spare parts.

Accurate measurement and regulation of fluid flow is the basis for ensuring the safety of petrochemical production processes, improving product quality and reducing energy consumption.

Due to the complexity and diversity of the medium for flow measurement, there is no universal flowmeter, and no flowmeter can be applied to various media under any different conditions.

Each flowmeter has its advantages and limitations in measurement, and flowmeters with different principles, structures and functions play a role in their respective applicable ranges.

Therefore, the selection of flowmeters needs to follow standard specifications and selection principles, and comprehensively consider various factors that affect flow measurement.

Application of flow meter in petrochemical industry

3.1 Application in Onshore Oilfield

Constrained by various factors, the drilling of deep wells and ultra-deep wells in Youshan generally has the problem of wasting high-density weighted materials.

In order to maximize the use of weighted materials, it is necessary to combine the relevant parameters of the centrifuge, the change of density difference, the viscosity of drilling fluid and other data. With the support of the calculation flow meter sensor, accurate data information can be obtained. Working speed and processing capacity. And scientifically control it with the help of computer to achieve the purpose of recycling.

In the use of flow meters in the petroleum industry, the selection of flow meters is very important. Therefore, we must fully consider the characteristics and working principles of flow meters and choose suitable flow meters.

3.2 Application on Offshore Drilling Platforms

At present, the development of offshore oil resources is in the ascendant, and a large number of offshore drilling platforms have been put into operation. They are mainly composed of modules such as public system, process production system and auxiliary process system.

According to the functional requirements of each plate, it is determined that it needs to rely on a large number of flow meters in its role.

For example:

The main measurement uses condensate oil as the fluid medium, its parameters are viscosity 0.89cp, temperature range 42～65℃, working pressure 6690～7411KPa, conventional flow 0.521m/h.

Combine the above basic data to filter the flow meter.
First, since the petroleum medium is not conductive, electromagnetic flowmeters can be excluded;
Second, condensate is highly dependent on pipelines, which are then delivered directly to end equipment. This can exclude turbine, ultrasonic and mass flow meters;
Finally, due to the limited space of the offshore drilling platform, the differential pressure flowmeter is also difficult to apply.

In order to prevent high cost, it is also necessary to exclude flow meters and positive displacement. In order to meet the requirements of small pipe diameter and low flow rate, it is also necessary to choose a rotameter.

mechanical water flow meter

Mechanical water flow meters refer to a type of flow meter suitable for clean water processes or applications. The working principle of a mechanical water flow meter is to measure the speed of water flowing through a pipe. This causes the piston or turbine to rotate. The volume flow of water is proportional to the rotation speed of the blades. Compared with electronic water flow meters, mechanical water flow meters may become clogged when the water is dirty or contains large particles. When the water flow is low, the mechanical water meter does not work well.

Working Principle of Ultrasonic Clamp on Water Flow Meter

Clamp on Ultrasonic Flow Meter adopts the measurement principle of time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.

The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.

By setting the flowmeter and considering the cross-sectional distribution of the flow velocity, the average flow velocity can be calculated. Then the volume flow of the fluid can be obtained according to the cross-sectional area of the pipe.

Notes:
V measure fluid velocity
M ultrasonic reflection times
D pipe diameter
θ The angle between the ultrasonic signal and the fluid
T up The time when the downstream sensor transmits the signal to the upstream
T down Time from upstream sensor to downstream
ΔT = T up – T down

Kerosene Gasoline

Pure kerosene is colorless and transparent liquid, pale yellow when it contains impurities. Slightly smelly. The boiling range is 180-310°C (not absolute, it needs to be changed according to the specific situation during production). The average molecular weight is between 200-250.

The melting point is above -40℃. The kinematic viscosity at 40℃ is 1.0～2.0mm2/s. Insoluble in water, soluble in alcohol and other organic solvents. volatile. Flammable. After volatilization, it mixes with air to form an explosive gas mixture. Complete combustion, sufficient brightness, stable flame, no black smoke, no lights, no obvious odor, and little environmental pollution.

Kerosene is miscible with petroleum-based solvents. The solubility of water is very small, and the solubility of kerosene containing aromatic hydrocarbons in water is greater than that of aliphatic hydrocarbon kerosene. Kerosene can dissolve anhydrous ethanol. Mixtures with alcohols separate at low temperatures in the presence of water.

Different uses of kerosene have different chemical compositions. The same kerosene has different physical and chemical properties due to different preparation methods and origins.

The quality of various kinds of kerosene decreases in turn: power kerosene, solvent kerosene, lamp kerosene, fuel kerosene, and washing kerosene.

Kerosene is a high-boiling hydrocarbon mixture with C11-C17 carbon atoms. The main components are saturated hydrocarbons, and also contain unsaturated hydrocarbons and aromatic hydrocarbons. Due to different varieties, it contains 28-48% alkanes, 20-50% or 8%-15% aromatic hydrocarbons, 1-6% unsaturated hydrocarbons, and 17-44% cyclic hydrocarbons. The number of carbon atoms is 11-16. In addition, there are a small amount of impurities, such as sulfides (thiols), colloids, etc. The sulfur content is 0.04% to 0.10%. Free of benzene, diolefins and cracked fractions.

Mainly used for lighting and fuel for various blowtorches, gas lamps, vaporization furnaces and kerosene furnaces; it can also be used as detergent for mechanical parts, solvent for rubber and pharmaceutical industries, ink thinner, cracking raw material for organic chemicals; glass ceramics Industrial, aluminum plate rolling, chemical heat treatment of metal workpiece surfaces and other process oils; some kerosene is also used to make thermometers. According to the use, it can be divided into power kerosene, lighting kerosene, etc.

Types of Kerosene Flow Meters

Which flowmeter should I choose to measure kerosene flow? We need to understand the corresponding situation of the measurement conditions first. The type of flowmeter that can be selected for different flow ranges can also be different.

For common measurement sites, trade measurement is generally involved. Our recommendation is to use a liquid waist wheel flowmeter or an oval gear flowmeter. Because volumetric measurement is used, this method measures accuracy. Especially suitable for trade settlement scenarios.

The second is the choice of liquid turbine flowmeter. Turbine flow meters are measured by the rotation of vanes inside the flow. Compared with the volumetric measurement method, the accuracy will be slightly less. But still maintain a stable 0.5 level of accuracy.

The measurement accuracy of other types of flowmeters, such as metal tube rotameter, orifice flowmeter, and vortex flowmeter, is significantly lower than that of the above two types of flowmeters. It is also optional if it is used for process control or internal monitoring.

what is upstream and downstream flow?

For pipelines where fluid flows, we must first understand the upstream and downstream fluids when installing the flowmeter.

The direction of fluid entry is upstream. The direction of fluid discharge is downstream.

The straight pipe section of the flowmeter is the straight pipe section that requires a certain length of the water inlet and outlet of the flowmeter. That is, the pipe in that section needs to be straight. There can be no elbows, valves and the like. Generally, the upstream length requirement will be longer than the downstream length requirement.

10D Upstream and 5D Downstream

When users use the orifice flowmeter, they generally require 10D Upstream and 5D Downstream for the straight pipe sections before and after the orifice flowmeter. So what does this D stand for? Today I will briefly talk about it.

The D represents the diameter of the pipe. For the orifice plate in the orifice plate flowmeter, the minimum requirements for the front and rear straight pipe sections are 10D Upstream and 5D Downstream. If there is a pump or regulating valve in front of the orifice plate, then the requirements for the straight pipe section are greater.
