The corrosion resistance of stainless steel flow meters

Stainless steel flow meters are generally used in corrosive environments. According to different measuring environments and measuring mediums, stainless steel such as 304/316/316L can be used.

304 stainless steel
As a widely used steel, 18Cr-8Ni has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties. It has good hot workability such as stamping and bending, and no heat treatment hardening phenomenon (non-magnetic, temperature -196℃ ~800℃).

316 stainless steel

18Cr-12Ni-2.5Mo is added with Mo, so its corrosion resistance, atmospheric corrosion resistance, and high-temperature strength are particularly good, can be used under harsh conditions; excellent work hardening (non-magnetic). Equipment used in seawater, chemical, dye, paper, oxalic acid, fertilizer, and other production equipment; photography, food industry, coastal area facilities, ropes, CD rods, bolts, nuts

316L stainless steel

18Cr-12Ni-2.5Mo low carbon as the low C series of 316 steel, in addition to the same characteristics as 316 steel, it has excellent resistance to grain boundary corrosion. Among the uses of 316 steel, products with special requirements for resistance to grain boundary corrosion.

316L stainless steel is not resistant to hydrochloric acid, because the chloride ion in hydrochloric acid will chemically react with the town in 316, and the reaction changes slowly, but there is still a problem after a long time. If it is convenient to use in the chemical industry, it is not necessary to consider materials such as lining plastic.

What is a flow meter?

A flow meter is an instrument used to measure the volume or mass of gas, steam, or liquid. Based on a specific industry, there are many different names for flow meters. Such as flow meters, flow indicators, liquid flow meters, flow sensors, etc.

Most flow meters consist of three parts: primary device, sensor, and transmitter. The job of the sensor is to sense the fluid passing through the main device. The raw signal from the sensor is then converted into usable data by the transmitter. The flow meter may consist of one or more physical devices because these components are combined most of the time.

Target flow meter measures oxygen:

The main measurement medium of this flowmeter is high viscosity, many impurities, easy to block, high temperature, low temperature, and strong corrosion. Oxygen is a pure gas, a small molecule gas, and its flow rate is slow. The target flowmeter does not meet its measurement characteristics.

Differential pressure flow meters (Bar-type series flow meters, orifice plates, wedge types, nozzles, V cones, etc.) measure oxygen:

All of them belong to a kind of throttling device. When measuring, the pressure is taken through the pressure taking port, and then converted into a flow signal output by the transmitter. In the process of converting the flow signal, the transmitter is prone to zero drift, and the stability of the flow is difficult to guarantee.

The pressure loss is larger than other flow meters, and it is difficult to accurately measure under low pressure and low flow rate conditions. Easy to get dirty and easy to block, large maintenance, can be used for general process control.

When there is no interference on site, the accuracy is greater than 2.5%, and the installation of large pipe diameter is time-consuming and laborious.

Metal tube float flowmeter measures oxygen:

This flowmeter is a mechanical flowmeter designed to measure small flow gases, with a measurement accuracy of 2.5%. There is no advantage in measuring large pipe diameters, hydrogen, and oxygen.

The flow range of DN300: 600～6000m3/h. The upper limit of flow can only reach 6000 cubic meters per hour, which cannot meet the on-site flow. Large pipe diameters are expensive and troublesome to install.

Biogas Flow Meters are instruments that can measure the flow of biogas. Could be a vortex flow meter, thermal mass flow meter, etc. Commonly used in biogas stations, biogas production fermentation tanks, etc.

renewable energy source-biogas

At present, the use of biogas is mainly concentrated in three major fields: rural areas, aquaculture, and industry.

Utilization of rural biogas
The comprehensive utilization of rural biogas can effectively solve the problem of living energy for farmers. The existing plant straw and animal manure in rural areas are used as raw materials. Use facilities such as biogas digesters to produce biogas after long-term fermentation. Provide farmers with gas, lighting, organic fertilizers.

Utilization of biogas in aquaculture
Livestock and poultry manure is put into the biogas project to produce biogas after fermentation. After the manure is fermented, it can be directly used as crop fertilizer, fish farming, pig feeding, seed soaking, etc. Promote the integration of agricultural planting and breeding. The main utilization methods are as follows: First, to provide gas for surrounding residents. The second is to provide electricity for the farm through power generation, and the remaining electricity will be connected to the grid.

Utilization of biogas in industry
The utilization of biogas in the industrial field is mainly concentrated in papermaking, brewing, food processing, sewage treatment and other industries. Industrial waste is used as raw material for fermentation to produce biogas. Mainly power generation and heat supply. Biogas can be used for internal combustion engine power generation, combustion support of large coal-fired boilers or to replace raw coal. Use small boilers to produce steam, etc.

Featured Biogas Flow Meters

Purpose of biogas flow measurement

In the process of biogas production and use, it needs to be flow metered. The main purposes are as follows:

• Provide reference data for biogas station. The purpose of installing flow meters in biogas supply stations is to provide basic data for the scheduling and control of biogas.
• Check the efficiency of fermentation tanks or landfills. Know the efficiency of the fermentation tank through the biogas flow. If the flow fluctuates unexpectedly, you can check the status of the fermentation tank in time.
• Control the combustion efficiency of the boiler. When a biogas boiler is burning, it is necessary to understand the flow of biogas to control the ventilation of the boiler. Excessive ventilation will reduce the furnace temperature. The ventilation rate is too low and the gas cannot be fully burned, causing waste and pollution.
• Control greenhouse gas emissions. Both CH4 and CO2 in biogas are greenhouse gases. Among them, CH4 is a greenhouse gas that is more harmful than CO2.
• Charges for civil biogas metering. Civil users install flow meters mainly for metering charges, and the management department conducts cost accounting.

Difficulties in biogas measurement

Biogas is a kind of gas that is very difficult to measure. It has the following characteristics:

• Very low pressure: the original biogas from the fermentation tank usually does not exceed 0.1 kg (10kPa).
• Composition changes: Biogas is composed of a variety of mixed gases. The composition of the biogas produced will fluctuate greatly depending on the raw materials for gas production.
• Large flow fluctuations: With changes in biogas raw materials, bacteria conditions, temperature fluctuations, etc., the output biogas flow rate will also vary greatly, so the flowmeter is required to have a larger turndown ratio.
• Water vapor: Biogas is produced by the fermentation of biomass, and the water in the biomass will be carried into the biogas. Therefore, the biogas usually contains saturated water vapor.
• Corrosive: Biogas usually contains H2S, although the content is low. But H2S will form corrosive hydrosulfuric acid after encountering water vapor. There is a greater potential for corrosion of metering components.

The Use of Beer Flow Meter in Beer Production Process

In the main technological process of beer production. For effective control in the production process. It is necessary to measure and control the intermediate raw materials – wort, sake in semi-finished products, raw juice wine in high-concentration dilution process, sterile carbonated water, final product filling and waste water generated during production.

Raw material allocation: During the preparation of raw materials for beer production. The main measurement parameters are weight and level.

Wort production: Wort is an important intermediate raw material for beer production. Its measurement involves the handover settlement between the front and rear processes (workshops), which is extremely important. Especially when the front and rear process workshops are separately accounted for. The measurement results are related to the completion of the respective production and economic indicators. Therefore, this measurement point is very important and sensitive, and accuracy is its primary indicator.

Wort has a certain viscosity, but there is no difficulty in the measurement of electromagnetic flowmeter. What needs to be considered is corrosion during the process. The flowmeter used at this measurement point can consider the electromagnetic flowmeter with PTFE lining (or PFA) and stainless steel electrode. It can prevent the corrosion of dilute hydrogen peroxide and alkaline water. Usually the diameter is between 50 and 100mm. The diameter of the flowmeter can be determined according to the flow rate and the matching process piping.

Fermentation: Sake that has been fermented and filtered. It will be transported to the next process through the pipeline – packaging. It also involves the custody transfer of the two departments. Accurate measurement of sake is also extremely important, otherwise unnecessary disputes will arise. The requirements for flow meters are similar to those for wort metering.

High concentration dilution: due to different production processes. Some beers are produced by blending high-strength ale. This requires strict control of the ratio of high-concentration original wine and sterile carbonated water. Guarantee the degree of beer after mixing.

In each production line, two electromagnetic flowmeters are required for proportional flow control. Generally, the diameter of the flowmeter for measuring wine is 50-100mm. The flowmeter for measuring water is 20-50mm. Depends on production scale. In order to ensure that the instrument has a high measurement accuracy. It should be ensured that the fluid velocity is above 1m/s. Make the flow measurement in the best working range of the instrument. At the same time, the time constant of the flowmeter should also be set smaller, generally 1 to 3s. In order to improve the sensitivity of the control and ensure the accuracy of the proportioning.

Flow meters in the production process of the beer industry have their own special requirements. For example, it is necessary to avoid the reproduction of bacteria, to facilitate frequent cleaning and to withstand the disinfection of corrosive alkaline water and hydrogen peroxide under higher temperature conditions. Specific requirements are as follows:

1. The sensor measurement circuit is simple. There are no obstructions and parts that tend to retain media.
2. All the parts and materials in contact with the medium meet the requirements of food hygiene. Such as compliance with FDA (US Food and Drug Administration), EHEDG (European Health Equipment Design Organization) requirements.
3. The parts in contact with the medium can withstand the temperature crash and corrosion when cleaning with steam, alkaline water and hydrogen peroxide.
4. When used in filling process, it should have fast response performance and high measurement accuracy.
5. Can adapt to low temperature (about 2 ℃) and humid working environment.

Vortex flowmeter for the volume of wet gas

When using a vortex flowmeter to measure gas flow, many wet gases are often encountered, such as wet air, wet gas, and wet chlorine.

Read more about: How Vortex Flow Meter measure efficiently? For steam, gas, liquid 

Physically, the commonly used mixture of water vapor and gas is called a mixed gas with certain humidity, that is, wet gas.

In wet gas, the density of water vapor constitutes a part of the density of the wet gas. However, in many cases, what needs to be measured and calculated is the volume or mass of dry gas. For example, this is the case when determining the heating value.

There are also wet air, wet chlorine, etc., as industrial raw gas. What companies need is a dry gas, so the “moisture” of these wet gases should be squeezed out when measuring, in order to better control the quality of products. Calculate the cost of the product.

The density of the wet gas is composed of the dry part of the wet gas and the water vapor contained in the wet gas. When the vortex flowmeter is used to measure the flow of the wet gas, because the vortex flowmeter only reflects the wet gas in the working state The volume flow rate cannot distinguish between the dry part of the wet gas and the amount of water vapor. Therefore, the volume flow measured by the vortex flowmeter is the volume flow of all wet gas. If only the volume flow rate of the dry part of the wet gas needs to be measured, the volume flow rate of the water vapor part should also be subtracted.

When using a vortex flowmeter to measure the flow of wet gas, because the vortex flowmeter only reflects the volume flow of the wet gas under working conditions, it cannot distinguish the dry part of the wet gas and the amount of water vapor.

Therefore, the volume flow measured by the vortex flowmeter is the volume flow of all wet gas. If only the volume flow rate of the dry part of the wet gas needs to be measured, the volume flow rate of the water vapor part should also be subtracted.

Precautions for measuring wet gas with vortex flowmeter

(1) Instrument selection

For the wet gas in the industrial gas, when the water vapor reaches the saturated state, water in the free state will appear in the pipeline. This state has a certain impact on the normal operation of the thermal and ultrasonic vortex flowmeters.

If the water in the free state adheres to the surface of the thermal detection element, it will affect the thermal conductivity of the thermistor element. It will affect the detection sensitivity and the lower limit of the range of the instrument.

If the water in the free state adheres to the surface of the ultrasonic transducer, it will also affect the transmission and reception of ultrasound. It will not only affect the transmission efficiency of ultrasound, but also the effect and sensitivity of ultrasound reception.

If this free water stays in the acoustic isolation annulus between the ultrasonic transducer and the tube wall, it will cause an acoustic “short circuit” phenomenon. Ultrasonic waves will diffract along the measuring tube wall and reach the opposite receiving transducer. The normal operation of the instrument was severely damaged.

If the water in the free state passes through the sound beam in the form of water droplets or mist, it will scatter and modulate the sound beam. It will become a serious random interference and affect the stability of the measurement.

Due to the above influences, when measuring wet gas flow, vortex flowmeters with force-sensitive detection should be used. For example, stress vortex flowmeters and capacitive vortex flowmeters. Because of the moisture in the wet gas and the free water, It has little influence on force detection and transmission.

(2) Prevent the corrosive effect of wet gas

Some gases such as chlorine, hydrogen sulfide, and so on. There is a certain degree of corrosiveness in the dry state, but the corrosiveness is not very strong. Once it becomes wet gas, its corrosive effect increases sharply. When selecting the meter, the vortex flowmeter that can withstand the corrosive effect of the medium should be selected in a targeted manner to prevent the invasion of wet gas.

(3) Installation method

When measuring wet gas with a vortex flowmeter.

If installed horizontally, the measuring section should be increased appropriately. Prevent saturated water from staying in the measuring tube of the instrument.
If installed vertically, the vortex flowmeter should be at a certain height from the horizontal pipe section.

(4) Operation and maintenance of the instrument

To prevent free water from accumulating in the pipe, a drain valve or drain valve should be installed at the lowest point of the pipe. Evacuate the sewage and dirt accumulated in the pipe regularly.

The main source of commercial LPG is the processing and refining of natural gas and oil. The raw materials usually contain excessive amounts of propane and butane. To prevent these two substances from condensing in the high-pressure exhaust pipe, they must be removed.

In the petroleum refining process. LPG is collected by titration from the dissolved crude oil mixed with a lighter specific gravity. At the same time, it can also be produced by the molecular fission of heavy hydrocarbons. Therefore, LPG is considered a subsidiary product. Its exact composition and characteristics usually vary from source to source.

Why is Precession Vortex Gas Flowmeter the right Propane flow meter?

Before that, people would use vortex flowmeters to measure propane.
Although the precession vortex flowmeter and vortex flowmeter are all fluid vibration flowmeters. However, the precession vortex flowmeter has the following advantages:

1. The generated vortex signal is stronger than that of a vortex flowmeter, so the lower limit Reynolds number is lower. When measuring gas flow, the lower limit flow rate can be as low as (1.5～2) m/s.
2. Because the vortex signal generated by the flowmeter is stronger than that of the vortex flowmeter. It is less affected by the upstream choke than the vortex flowmeter. Therefore, the length of the upstream straight pipe is much shorter.
3. The meter coefficient K is 1 to 2 times larger than that of the vortex flowmeter.

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.
