2Product Description
This section covers the reference and specification data, as well as ordering
information.
2.1 Introduction
Electromagnetic flow meters are also called as Magmeters. They are non-contact
instruments used for measuring the volumetric flow rates of any fluids that can
adequately conduct electricity in closed pipelines. These instruments are highly
accurate, reliable, and stable devices that are used in various high-pressure industrial
processes.
2.2 Measuring Principle
The Tek-Flux 1400A Electromagnetic flow meter operates on the principle of Faraday’s
Law of Induction. According to this principle, any change in the magnetic flux linked to
an electric circuit causes an electromotive force (or voltage) to be induced in this
circuit. The induced voltage is therefore directly proportional to the rate of change of
magnetic flux with time.
The flow meter typically consists of two electromagnetic coils that are mounted on
opposite sides of a non-magnetic measuring tube. Two electrodes are fitted inside the
tube to detect the voltage generated by the conducting fluid. Although these
electrodes come into contact with the fluid, they do not obstruct its flow.
When current is applied to the coils, they generate an alternating magnetic field across
the cross-sectional area of the tube. A fluid flowing through the magnetic field acts as
a conductor, and a voltage is induced. The induced voltage is picked up by the
electrodes and sent to a transmitter that is either mounted on the flow meter or
connected remotely. The transmitter calculates the volumetric flow rate and displays
the output.
The induced voltage is calculated using the following equation:
U = B x d x v
Where,
U = Voltage Induced by the Conducting Fluid
B = Magnetic Flux Density
d = Distance Between the Electrodes
v = Average Velocity of the Conductor (i.e. fluid flowing in the tube through
the magnetic field)
Since the magnetic flux density and the distance between the electrodes remain
constant, the induced
voltage is directly proportional to the conductor velocity.
The value of the velocity is used to calculate the volumetric flow rate as follows:
Q = A x v
Where,
Q = Flow Rate
A = Area
v= Average velocity

3Installation
This section covers instructions on installation and commissioning. Installation of the
device must be carried out by trained, qualified specialists authorized to perform such
works.
CAUTION
•When removing the instrument from hazardous processes, avoid direct
contact with the fluid and the meter
•All installation must comply with local installation requirements and local
electrical code
3.1 Correct Mounting Point
•Correct mounting point is important for the installation of a flow meter. Wrong
point may influence measuring accuracy or flow meter service life, or even
damage the flow meter.
•The axis for measuring electrode shall be approximate to horizontal direction.
(Angle with horizontal line shall be no more than 10°)

TechnologySolutions
Instruction Manual
Tek-Flux 1400A
www.tek-trol.com
13
At flow meter upstream, there should be straight pipe no less than 5D and no less
than 2D at flow meter downstream. (D is the inner diameter of the flow meter)
3.2 Requirements for Measuring Flow Meter Accuracy
•Medium must be conductive;
•The pipe should be completely filled with the medium;
•Medium conductivity should be homogeneous to avoid severe disruption. If chemical
substances need be injected into the pipe, the injection should be operated at
upstream side of flow meter;
•Magnetic flow meter system should be connected to the ground;
•There must be a straight pipe run no less than 5DN at flow meter upstream and 2DN
at flow meter downstream. (DN is the internal diameter of the pipeline);
•Do not install the flow meter near large electrical machine or transformer in order to
avoid the electromagnetic interference.
3.3 Installation Condition
NOTE
Do not expose the electronic unit box to direct sunlight; in case of outdoor
installation, use a suitable protection shield
•Install flow meter at relative low of horizontal pipe or in an upward vertical direction.
Do not install the flow meter at the highest point of the pipe and in the vertically
downward direction

•Install flow meter at the rising pipe
•For installing at open pipe, flow meter should be installed at relative low. If the fall in
the pipe is more than 5m, vent valve should be installed at the sensor downstream
where it should have back pressure
•Control valve and stop valve should be installed at the downstream of sensor and not
at the upstream side.
•Sensor should be installed at the outlet of pump and not at the inlet

4.1 Safety Instruction
•Please cut off power supply before connecting the device
•Check the cable model before connecting the cable
•Follow procedure for cable into lead collar: at first, loosen the gland nut on lead collar
and take off blind; secondly, put gland nut and rubber ring on cable, make the cable
through lead collar; finally, straighten out cable, screw gland nut tight to make rubber
ring press cable.
•When wire stripping, do not damage insulating layer which should be reserved.
4.2 Grounding
Grounding of Tek-Flux 1400A is very important. Bad grounding will result in abnormal
operation. Flow meter sensor part should have separate grounding cable (whose
sectional area of copper core should be 1.6mm2, ground resistance should be less than
10Ω.).
4.2.1 Grounding Ring
If the pipeline connected with sensor is insulative, grounding ring will be needed, the
material should be same as electrode material. If the medium is abrasive, then
grounding ring with neck should be selected.

TechnologySolutions

4.2.2 Grounding Mode
If flow meter is installed in metal pipeline, there should be no insulating coating on
pipeline in wall.
•If flow meter is installed in the pipeline with insulating paint, the inner part of
the grounding ring should be painted on both the sides of the sensor.
4.3 Transmitter Connections
4.3.1 Basic Circuit of the Transmitter
The converter can supply the exciting current to the coil in the sensor of
electromagnetic flow meter; the head amplifier amplifies the electromotive force
from the sensor and converts it into standard signals of current or frequency so that
the signals can be used for displaying, controlling, and processing.
