2 Product Description

2.1 Introduction

Tek-Flux 1400C Utility Electromagnetic Flow Meter is widely used for high-pressure
applications with highly accurate and reliable measurements. Tek-Flux 1400C is used to
measure flow rate for various conductive liquids. This Inline Battery-Powered Magmeter is
specially designed for applications where availability of electricity and power supply is
unavailable. The Tek-Flux 1400C Magmeter provides 5 years battery life, which minimize the
maintenance and enhance the productivity of smart measurements in field instruments.

2.2 Measuring Principle and Operation

Tek-Flux 1400C Utility Electromagnetic Flow Meter operates on the principle of Faraday’s
Law of Electromagnetic Induction. It describes the relationship between an electrical
conductor and the voltage, which is generated by magnetic field. The induced voltage is
directly proportional to the velocity of fluid flowing through a magnetic field and passes
through the transmitter. The transmitter converts this voltage into a quantifiable flow
velocity, where volumetric flow rate of the fluid is determined by the velocity.

Technology

Fig 1: Tek-Flux 1400C Utility Electromagnetic Flow Meter

In an Electromagnetic Flow Meter, a magnetic field is generated by a pair of diametrically
placed electrical coils. These electrical coils are mounted externally to the flow tube. As the
conductive liquid passes through this Electromagnetic field, the force of the magnetic field
causes the negatively and positively charged particles of the liquid to separate. This
separation causes an induced voltage between the electrodes and the sensor. This induced
voltage is directly proportional to the velocity and perpendicular to both the liquid flow and
the electromagnetic field direction. The sensed voltage is further processed by the
transmitter to provide a standardized output signal or displayed in an appropriate
engineering unit.

2.3 Flow Computation

The flux density of the electromagnetic field and the distance between the electrodes are
constant. Therefore, the induced voltage is the function of liquid velocity as below:

Where,
E = Induced Voltage
K = Flow tube Constant
B = Magnetic Field Strength
v = Mean Flow Velocity
D = distance between Electrode

Volume flow is calculated by following equation:

Therefore, From Equation 1 and 2:

Hence, induced voltage or e.m.f is not affected by the physical properties of liquids like
temperature, pressure, density along with conductivity above the minimum threshold level
of measured liquid. When the pipe is completely full of liquid, the flow meter provides
reliable and accurate measurements.
The electromagnetic field coil assembly is excited by the pulsed DC technique, which
eliminates the noise and provides zero correction automatically.

3.1 Pre-Installations Checks

• Re-confirm the compatibility of the process liquid with the materials of the Flow Tube
liner and the electrodes as ordered by you.

o Confirm the compatibility of all components i.e., if process liquid is a mixture of

different components.

o Check the compatibility of process liquids that contain harmful contaminants.
o Note that the severity of corrosion of material is depending upon the temperature

and the concentration of the process liquid.

o Corrosion due to service liquid reduces the life of Flow Meter.

• Ensure that the selected Flow Meter size is suitable for the flow rate to be measured.

• Note that the velocity under normal conditions should be between 0.2 m/s and 12 m/s.

• Confirm that an appropriate Earth pit is available, which is close to the Flow Tube for

proper Grounding.

3.2 Installation of Flow Tube

3.2.1 Selection of Mounting Locations

The Tek-Flux 1400C Utility Magmeter must be installed in the pipeline at a point which
satisfies the following requirements.

• To avoid erratic measurement results, flow tube must be full of liquid.

• Ensure that the Electrodes axis is horizontal within ±15 degrees.

• Ensure straight pipe lengths on both side of the flow tube (5D at upstream and 3D at

downstream from the center of the flow tube).

Fig 8: Straight Run Requirement

• Flow Tube may be installed in horizontal Pipelines preferably, with a slight upward
gradient in the direction of flow.

Fig 9: Horizontal Installation

• Never install the flow tube in empty or partially full pipeline.

• Never install the flow tube in vertical pipelines, where the liquid flow direction is

downward.

Fig 10: Vertical Installation with Liquid in the downward direction

• The piping layout must be preventing of any air content. The entrained air should be
carried out of the flow tube by the liquid flow or by buoyancy at zero flow.

• Ensuring installation location in a way, that water or moisture does not enter the
electrical terminations area.

• If the connecting pipeline is not electrically conducting or is lined with insulating
material, strap the grounding rings to the detector head flanges at either end.

Fig 11: Strap the Grounding Rings

• Use empty pipe detection option to obtain correct flow status and prevent erratic
output for completely draining out the process liquid.

3.2.5 Checking for sealing

Once the flow tube has been mounted, fill the pipeline preferably with water instead of
process liquid for confirmation of leak free mounting.
If even minor leaks are noticed, following instructions are refer:

• Check the axial alignment of the flow tube with the upstream and downstream pipe
lengths.

• Cleanliness of gasket.

• Use rating of gasket material and proper tightening of the bolts.

• After eliminating the leakages, allow the process liquid to pass through the pipeline.

NOTE

the corresponding national standards and regulations and the Safety Instructions or
Installation or Control Drawings.

4.1 Instructions

• The Transmitter is delivered with a cable (pigtail) for making connections, so do not open

the cover of the Transmitter.

• Install a junction box with an appropriate IP rating and mount it close to the Flow Meter at

a distance that allows terminating the cable of the Transmitter.

• Never extend the Transmitter Cable to join another cable.

• Use ferrules for each wire and crimp the ends of the conductors with appropriate cable

lugs.

• Before making various connections, understand how these connections are to be done.

• The Schematic is shown in figure 15.

4.3 After making all the connections

• Confirm that installation has been done and completed, as described in this manual.

Then, the Flow Meter is ready for operational use.

• Inspect and confirm that the O-rings and gaskets of the covers of the Transmitter.

• The Junction Box is intact and properly seated, and both the covers are well fastened.

• Allow the process liquid to start flowing through the Flow Tube.

• Ensure that the flow rate is within the specified limits for the Flow Meter.

• The excessive flow rate could damage the Flow Tube lining.

• The Transmitter is delivered in a powered-up condition, duly calibrated, and configured

for the range of flow rate measurement as per your requirement.

• The Flow Meter will start indicating the flow rate and the totalized flow values

alternately, drive the pulse output, and start communicating over the Modbus.

5.3 Operational Precautions

• Keep the cover of the Transmitter well fastened.

• Take care of the O-ring or gasket to avoid damage and fixed adequately for effective

sealing.

• Keep the cable gland nut tight and ensure that the cable is gripped uniformly around its

circumference. This will prevent any ingress of moisture or water into the Transmitter.

o Stop the flow through the Flow Tube by shutting off the valve, which is immediately

at the downstream of the Flow Tube.

o This way, the Flow Tube will remain filled with liquid.
o The display must be within 0.075% of the FS value.

o Improper grounding.
