Ø Performance characteristics

·Not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity.

·The measuring tube has unobstructed flow components, no pressure loss, and low requirements for straight pipe sections.

·The sensor can be equipped with a grounding electrode to achieve good grounding of the instrument.

·The sensor adopts advanced processing technology, which enables the instrument to have good anti negative pressure capability.

·The converter adopts a liquid crystal backlight display, which makes it easier to read under reflected sunlight or in a dark room.

·By using infrared remote control to set parameters, it is possible to safely set without opening the cover of the converter in harsh environments.

·The converter has functions such as self diagnostic alarm output, empty load detection alarm output, flow upper and lower limit alarm output, and two pole flow value alarm output.

·Not only can it be used for general process detection, but it is also suitable for measuring slurry, pulp, and paste liquids.

Performance

scope of application

PTFE

（F4）

1. It is a chemically stable material in plastics; Capable of boiling hydrochloric acid, sulfuric acid, nitric acid, and aqua regia. It can also withstand concentrated alkali and various organic solvents, but is not resistant to corrosion from chlorine trifluoride, high-temperature oxygen trifluoride, high flow rate liquid fluorine, liquid oxygen, and ozone.

2. Poor wear resistance.

3. Poor ability to resist negative pressure.

1.120 ℃, 150 ℃ (special order)

2. High temperature, strong corrosive media such as concentrated acid and alkali

3. Sanitary media

FEP

（F46）

Same as F4, the wear resistance and negative pressure resistance are higher than F4

1.120 ℃, 150 ℃ (special order)

2. Used in situations with high temperature and negative pressure.

Polyurethane rubber (PU)

1. It has excellent wear resistance (equivalent to ten times that of natural rubber).

2. Poor acid and alkaline resistance.

3. Cannot be used in water mixed with organic solvents.

1.<80℃

2. Neutral and strongly worn mineral slurry, coal slurry, mud, etc.

chloroprene rubber

（CR）

1. It has excellent elasticity, high tensile strength, and good wear resistance.

2. Resistant to corrosion in general low concentration acid, alkali, and salt media, but not resistant to corrosion in oxidizing media.

1.80 ℃, 120 ℃ (special order)

2. General water, sewage, weakly abrasive mud, and slurry.

Electrode material

corrosion resistance

Molybdenum containing stainless steel
0Cr18Ni12Mo2Ti

Used for industrial water, domestic water, and sewage, it is a weakly corrosive medium that can be widely used in industries such as petroleum, chemical, urea, and vinylon.

Stainless steel coated with tungsten carbide

Used for non corrosive and highly abrasive media.

Hastelloy B (HB)

It has good corrosion resistance to hydrochloric acid of all concentrations below boiling point, as well as to non oxidizing acids, bases, and non oxidizing salt solutions such as sulfuric acid, phosphoric acid, hydrofluoric acid, and organic acids.

Hastelloy C (HC)

Capable of withstanding corrosion from oxidizing acids such as nitric acid, mixed acids, or mixtures of chromium and sulfuric acid, as well as oxidizing salts such as Fe⁺⁺⁺、 Cu⁺⁺Or corrosion containing its oxidizing agent. Corrosion caused by hypochlorite solutions above room temperature and seawater.

Titanium (Ti)

Capable of withstanding corrosion from seawater, various chlorides and hypochlorite salts, oxidizing acids (including fuming nitric acid), organic acids, alkalis, etc., but not resistant to corrosion from relatively pure reducing acids (such as sulfuric acid, hydrochloric acid). But if the acid contains oxidants (such as nitric acid, Fe)⁺⁺⁺、 Cu⁺⁺）At this time, corrosion is greatly reduced.

Tantalum (Ta)

Has excellent corrosion resistance, similar to glass. Except for hydrofluoric acid, fuming nitric acid, and alkali, it can withstand corrosion from almost all chemical media (including hydrochloric acid, nitric acid, sulfuric acid, and aqua regia).

platinum-iridium alloy

Suitable for almost all chemical substances, but not for aqua regia and ammonium salts.
