1. Operation Principle
<>The operation of a magnetic flowmeter or mag meter is based upon Faraday's Law, which
states that the voltage induced across any conductor as it moves at right angles through a
magnetic field is proportional to the velocity of that conductor.
Faraday's Formula:
E is proportional to V x B x D where:
E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor
To apply this principle to flow measurement with a magnetic flowmeter, it is necessary first to state
that the fluid being measured must be electrically conductive for the Faraday principle to apply. As
applied to the design of magnetic flowmeters, Faraday's Law indicates that signal voltage (E) is
dependent on the average liquid velocity (V) the magnetic field strength (B) and the length of the
conductor (D) (which in this instance is the distance between the electrodes).In the case of
wafer-style magnetic flowmeters, a magnetic field is established throughout the entire
cross-section of the flow tube (Figure 1). If this magnetic field is considered as the measuring
element of the magnetic flowmeter, it can be seen that the measuring element is exposed to the
hydraulic conditions throughout the entire cross-section of the flowmeter. With insertion-style
flowmeters, the magnetic field radiates outward from the inserted probe (Figure 2).
2. Main Features andApplications

carefully read the relevant sections.
Sensor installation method for the flange connection. Criteria and process pipe welding flange
screw holes in the inter-position, bolt can be passed smoothly to facilitate the integration
between the sensor and process piping.
Installation must ensure that sensors Center and the process pipe center line, and then a good
grounding line, otherwise it would cause measurement error.
According to the work of instrument characteristics and technical characteristics, the choice of
instrument installation environment should pay attention to:
(1) The instrument should be installed at the ventilation to dry, avoid installing at the place easy
accumulation water.
(2) The instrument should try to avoid just sun shine and rain. Open-air installation, should
keep out rain in places;
(3) Installation of places as much as possible to avoid strong vibration;
(4) as far as possible to avoid a strong electromagnetic field equipment; such as large motors,
large transformers.
(5) Select the ease of maintenance, activities, convenient place.
Installed on the sensor in the pipeline, we should note the following points
(1) sign the direction of the flow sensors and pipeline flows in the same direction within the
medium;
(2) The need to ensure that sensor tube is full filled with the measured medium;
(3) The sensors should be five times the upstream straight pipe section D above, the sensor
should be three times the downstream straight pipe section D above (available from the center
of sensor , D to measure the pipe diameter);

3, with a threading instrument connectors, cable connectors must be approved by
threading into the instrument cavity (see circle). After the wiring , waterproof joints
should be tightened to ensure that moisture and corrosive gases do not enter
the electronic part.
4, Input and output lines recommend the use of the installation of conduit,
conduit tube be recommended thick solid brass or soft metal pipes Road. Conduit should be noted that the order
to prevent flood water flowing into the conduit or conduit into the internal instrumentation. Input power line and
signal lines should be separated through their respective special perforated cavity into the instrument, prohibited
parallel and banding together.

Pay attention to the following questions on connect the power supply :
1, the power cable of inside the sensor will not wound.
2, the power input line should separated with other input and output lines , threading through the
holes into their own dedicated instrument cavity.
3, noted that the positive and negative polarity DC power supply, if the reverse then the
instrument does not work.
4, power supply should have a good grounding in order to protect the operator's personal safety.

Instruments
The converter current output electrical isolation has been achieved. Output to take an active
approach. Current output mode 4-20mA, 20mA current output value from the corresponding traffic
parameter item "scale flow of value" is determined (reference to factory nameplate on the
instrument measuring range a value). The maximum current output load resistance of 750Q, the
load resistance includes the cables used to connect the resistance. Current output cable is
recommended RWP2x16/015 PVC insulated sheathed cable shield. 2.
Counter
The Transmitter frequency, pulse output has been achieved electrical isolation, the output for the
active mode (see above chart). Transmitter frequency, pulse output with transistor output mode.
Maximum pulse output frequency 5KHZ, the output pulse amplitude of 24V. Active mode the
maximum load current 50mA, passive mode the maximum load current 0.2A. As the frequency
and pulse output terminals are shared, it is not to choice two output modes. Users can set the
parameter "frequency output" to select the work. Frequency output upper limit corresponding to
the measured flow value by the parameter item "scale flow value" decision (reference instruments
to measure the scope of a factory nameplate values). Pulse output equivalent by the parameter
'pulse equivalent L / P "decision.
Transmitter communication with RS485, MODBUSASC, MODBUSRTU communications
capabilities (requires a user specified when ordering). Available through the "485 output
communication protocol" parameter is set to specify. Instrument Communication Interface specific

Before connect power, follow the manual of the first part of the note 1,2 and sensor part of
the installation manual to verify whether the system is properly installed and connections.
End customer can directly run instrument, the reason is including sensors and signal
transmitter of two parts, all of the data have been based on user requirements and technical
specifications of the company's manufacturing process in the factory setting.
After complete correct electric connection, run power on instrument. Instrument transmitter first
implementation of the initialization; display the company logo (see below). Wait 3 seconds after the
instrument into the own measurement mode, immediately began to flow measurement and
displays the current flow measurement value or other self-assemblies off information. If there is no
meter to power after the show (display without backlight), then the power supply and connectivity
in identifying ways to meet the requirements, may view the instrument power supply fuse is intact
(you can see the 8 common faults and processing).
