Domestic ultrasonic flowmeter which good

• Domestic ultrasonic flowmeter，There are many types of flowmeters in the market, such as vortex street flowmeter, target flowmeter, electromagnetic flowmeter, thermal gas mass flowmeter, etc. Different industries are different in choosing flowmeters.

I. sewage treatment

Sewage is divided into industrial sewage and domestic sewage

Sewage is a mixture of solid and liquid. Industrial sewage is difficult to measure due to its complex composition and corrosiveness, so most instruments cannot measure it.

The main instruments used in sewage treatment are electromagnetic flow rate and a small number of open channel flowmeters.Electromagnetic flowmeter has a variety of lining and electrode materials to choose, high precision, corrosion resistance, is the main force in measuring the flow of industrial sewage and domestic sewage.

2. Chemical industry

The chemical industry is one of the most widely used flowmeter industries. Almost all kinds of flowmeters are used in the chemical industry.

1. When measuring air, steam and other gases, vortex flowmeter is most commonly used, and v-cone and orifice are also used;

2. When measuring viscous oil media, positive displacement meter has good application and measurement effect;

3. Orifice plate and v-cone are most used in measurement of ammonia liquid and liquefied gas;

4. Measure all kinds of light oil, such as diesel oil, gasoline, non-corrosive chemical solvents, etc. Turbine flowmeter is the first choice;

5. The metal rotameter is also widely used in the chemical industry, mainly in the measurement of small flow and process control;

6. Electromagnetic flowmeter is the only choice in the measurement of chemical wastewater.

Food and medicine industry

Requirements for flowmeter in food and medicine industry: 1.2. The surface is made of stainless steel, anti-corrosion and anti-rust;3. Quick-loading structure is easy to clean and maintain.

1) sanitary electromagnetic flowmeter

The main measurement of clean water, juice, emulsion, liquid medicine and so on.

Usually for the clip type connection, easy to remove, clean;The material is stainless steel, the lining is FEP, PFA and so on.Because there is no dead Angle on the structure, it is convenient for high-temperature disinfection and is most widely used.

2) vortex street flowmeter

Mainly measure steam, water, beer, cooking oil and so on.

Material for stainless steel, flange clamping, easy to use, the disadvantage is that the accuracy and electromagnetic flowmeter is slightly worse.

3) turbine flowmeter

At present partial manufacturer rolls out wholesome turbine flowmeter, majority is flange clamp is installed, also have clip type structure, measure accuracy and electromagnetism are equal, because prohibit oil must use sealed bearing, must change regularly.
