Multi Language Integrated Electromagnetic Flow Meter , Electrical Flow Meter
Content:
It composed of sensor and converter, be used to measure electrical
conductivity of liquid or solid. And the electrical conductivity should be
over 5υS/cm. Meanwhile,It can also be used to measure various mediums
like acid, alkali, saline solution,paper pulp,ore pulp and so on.
But these mediums can’t contain a lot of magnetic materials and bubbles.
MTF electromagnetic flow meter is used for measuring the flow conductivity liquid,
which is widely used in flow measuring of Metallurgy, Chemical industry,
Paper industry, Environmental protection, Oil industry, Textile industry,
Food industry and City administration, Water works,etc.
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.
Selection 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 the 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.
The installation of the sensor on the cathodic-protection pipe.
Waining:
1) the ground ring is amounted on the two surface of the sensor,it must be isolated
from the flange connecting to the pipe, and make the sensor and ground ring connected
ground wire 2,the material of ground ring should be resistant to the corrosive medium,
standard material that the manufacturer provide is stainless steel ICr18Ni9Ti.
2) The flange on the both sides of instrument should be connected to the sensor by the
cross-sectional area of 16mm copper wire to make the cathodic protection potential and
sensor isolated. the cathodic protection pipeline and sensor are isolated to the both sides
of the connecting duct. When installing, please note the following points:
The ground ring isolated to the flange of pipe must be installed on the both sides of the
meter(and the grounding of low mete,and measuring ground must be connected to each
other).
The pipe and flange must be connected with copper wire (L),and avoiding connecting to
the sensor.
The flange bolts must be insulated (as pictured)the customer must use the liner and gasket
made of isolated materials.
