IP65 IP67 IP68 MTF Battery Operated Flow Meter Explosion Proof Long
MTF electromagnetic flow meter, composed of sensor and converter,
on Faraday’s law of electromagnetic induction. It is used to
conductivity of liquid or solid. Generally, the conductivity should
be over 5υS/cm
MTF electromagnetic flow is used for measuring the flow
which is widely used in flow measuring of Metallurgy, Chemical
Paper industry, Environmental protection, Oil industry, Textile
industry and City administration, Water works,etc.
1). No baffles and running part inside the measuring tube,
therefore no additional flow
loss and no jams happen. Especially for measuring the flow of
solid-liquid object, for
example, sewage, mud pulp and CWS (coal water slurry).
2). It can be used in kinds of strong acid and alkali in chemical
3). High accuracy, it is up to ±0.2%,it is capable for testing
4). It provides the function of zero correction of sensor and
automatic zero adjustment.
5). It has lightning-protection and electricity-protection
circuits. The effective,
anti-interference circuits apply to all kinds of bad environment.
1). It’s the first one to apply “Fuzzy Algorithm” technology to the
electromagnetic flow meter in China. It has the function of
2). It is the first domestic company that has electromagnetic flow
meter with HART
communication function .
3). Explosion-proof design accords with the national
requirements and has been approved by tests and can be used in
4). It adopts the international leading excitation technology,
which circuit is simple,
stable, and reliable.
5). It has the function of infrared remote control and button
operation so as to make
the operation more convenient.
6). It provides the function of zero correction of sensor and
automatic zero adjustment.
7). It has multi-language interface to satisfy all the users’
8). It has the function of self-adjustment and self-checking.
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
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
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.
Sensor diameter selection
The selection of the sensor diameter is not the same as the
diameter of pipe.This option
applies to the following:
A.for Low flow velocity in the pipe and the stable flow rate, to
meet the requirements of the instrumentation on the flow rate
range,we should increase the flow rate of partial area and
select the sensor diameter smaller than the pipe diameter ,and
install another different -
diameter pipe before the sensor.
B.In terms of the price, for the magnetic flow meter with large
diameter, the larger diameter
you want, you higher price you will pay; for the low flow rate in
the pipe and stable parameter,
the selection of small diameter would be better. It will not only
make the meter work in good condition but also reduce the cost.
