Flow Meter
MAGYN Serials Intelligence Electromagnetic Flow Meter
conducts measurement based on the principle of the Faraday
Electromagnetic Induction Law. When conductive liquid flows
in a magnetic field and incises the magnetic flux, there
generated induced electromotive force E in the conductor,
as below.
E=KBVD
Where,
k--------Instrument constant
B--------Magnetic induction density
V--------Average velocity in the cross section of a measured
pipe
D--------Inner diameter of a measured pipe
When measuring a flow rate, the conductive liquid flows
at a velocity of V perpendicularly through a magnetic field,
which inducts a voltage that is direct proportional to the
average velocity. The inducted voltage signal is measured
on two or more poles immediately contacted with the liquid,
sent to a convertor through a cable, and then
intelligentized
before it is transferred to and displayed in a LCD or converted
into a 4¡«20mA or 0¡«1kHz output. Patent No.: ZL 03 2 63802.7
Feature and Usage
|
Absolute |
When the temperature, pressure, viscosity and density
of the measured fluid changing, the flow meter do
not be influence. |
|
Easy Maintenance |
No moving parts in measuring tube, so easy maintenance.
|
|
Widely Use |
Can measure conductivity liquid, fiber content
conductivity liquid, solid content conductivity
liquid, suspending material conductivity liquid
whenever fiber or solid. |
|
Easy Install |
Install any angle only need liquid full of the pipe.
Straight pipe require 5D for upper stream and 2D
for down stream |
|
Large Turndown Ratio |
The turndown ratio can reach to 1:100 |
|
Enclosure |
For DN15~DN1200 is IP68 |
|
High Intelligence |
Back light English/Chinese LCD display, Meun setting control, three grades password protection, Two-way
measuring available, slight signal removal, Auto
flow compensate and other function. |
|
SMT Technical |
Intelligence self-detect and self-diagnoses, many
kinds of alarming |
|
SMART Excitation |
Low power consumer, zero stability, longtime reliability
|
|
Multi- Output |
4-20mA or 0~10mA current output, Standard Pulse
Output, RS485 computer communication output |
|
Slect the right lining and electrode material can
measure nearly all conductive liquid. |
|
The power supply system has good voltage vibration
adaptability. The power system also resist well
electromagnetic interfere. |
