Selectrion of Ground Ring

?

If the pipe connecting to the meter is insulated,the ground ring is needed, generally

metallic or non-metallic grounding rings or grounding electrode (non-metallic) material is

available to adapt to the corrosion of the measured material.

?

If the measured medium is abrasive, ground ring with neck should be used to protect

lining material of two sides and to prolong its life.

?

In order to make the reliable operation of the instrument, and to improve measurement

accuracy, free from outside interference of Send potential,the sensor should have separate

ground wire, and the ground ring of both sides of the sensors should be fitted when the

ground resistance, in the pipe connecting to the sensor or non-metallic pipe, is less than 10Ω.

Electrodes selection

?

- - - -
Electrode material | Main performance |
316L | Good resistance to the corrosion of nitric acid, <5% Sulfuric acid under room temperature, Acetic acid, Alkaline fluid, Sulfite under certain pressure, seawater and Acetic acid, etc. It can be widely used in the petrochemical, urea, vinylon. |
HB | Good resistance to the all the concentration of hydrochloric acid below the boiling point, also resist the corrosion of non-oxidizing acid, alkali, salt like sulfuric acid phosphoric acid hydrofluoric acid, organic acids. |
HC | Resist the corrosion of oxidizing acids like metric acid, mixed acid, the mixture of chromium acid and sulfuric acid, and salts of oxidative, like Fe+++,Q+++,and some other oxidants, like hypochlorite salt solution higher than normal temperature and seawater. |
Ti | Resist the corrosion of seawater, various chlorides,hypochlorite, oxidizing acid(like su-lfuric acid, hydrochloric acid). But if acid includes oxidants(like nitric acid,Fe+++,Q+++),the corrosion resistance will decrease. |
Ta | Good corrosion resistance similar to glass. Resist the corrosion of chemical medium(including hydrochloric acid and fuming sulfuric acid),but can not be used for Sodium hydroxide fluid. |

Electromagnetic flow meter for measuring Heat (Energy)

?

MTF electromagnetic flow meter also have a function for measuring heat (energy)

(Please inform us when you place orders). it is a kind of metering instrument for measuring

the heat (energy) from heat-conducting fluid which belong to the heat exchange system.

Through carrying high accuracy and stable Platinum resistance (PT1000)as measuring elements, to make the heat(energy)meter has a very excellent

Selection of Protection Level


According to the GB4208-84 IEC standard (IEC529- 76) on
the protection level:


IP65 means water-jet type; it allows the taps spray from
all the directions of the instrument. the pressure is
30kPa(0.3bar),the output of the water is 12.5l/m,and the taps
is 3 meters far from the instruments.

?

IP67 means anti-immersion type, it can be submerged in the

water in a short time, when testing, the highest point in the

experiment should be at least 15cm underwater and last for

at least 30 minutes.


IP68 means Submersible-type, it can work in the water for
long-term, Its maximum depth in the water should be
consulted by the manufacturer and the user.


The choice of protection should be selected in
accordance with the above requirements, as well as the actual
instrument conditions. If the meter works under the ground and
always submerged by the water, IP68 should be selected, If
the instrument is installed above ground, IP65 is optional.
