1 Introduction

1.1 Tek-Flux 1400B Series

Tek-Flux 1400B Electromagnetic Flowmeters are used to measure the flow rate of a variety of conductive liquids. It functions according to the fundamental principle of Faraday’s law of Electromagnetic Induction, which describes the relationship between an electrical conductor and the voltage it generates when moving within a magnetic field.

1.2 Principle of operation

In an Electromagnetic Flowmeter, a magnetic field is generated by a pair of diametrically placed electrical coils mounted external to the flow tube. As the conductive liquid passes through this Electromagnetic field, an electrical voltage is induced in the liquid, which is directly proportional to its velocity. This induced voltage is perpendicular to the directions of both - the liquid flow and the Electromagnetic field.
A pair of diametrically placed electrodes mounted along the inner wall of the flow tube and in the direction of the induced voltage, sense this induced voltage. The sensed voltage is further processed by the Transmitter to indicate the flow rate and generate a standard output signal proportional to the measured flow rate.

1.3 Flow Computation Basics

The flux density of the Electromagnetic field and the distance between the Electrodes are constant for a given Flowmeter. The induced voltage is therefore only a function of the liquid velocity.
E = K.B.V.D
Where ­E = Induced voltage B = Magnetic field strength K = Flow tube (meter) constant v = Mean flow velocity D = Distance between the electrodes
And the volumetric flow is calculated as –
qv = (π x D2/4) x v
Therefore,
qv = (π x E x D) / 4 K B
The induced voltage is not affected by the physical properties of the liquid like temperature, viscosity, pressure, density and conductivity, as long as the conductivity of the measured liquid is above a minimum threshold.

3 Preinstallation Check

a. Re-confirm the compatibility of the process liquid with the materials of the Flow Sensor
liner and the electrodes as ordered by you.
• If the process liquid is a mixture of different components, confirm the compatibility of all the components.
• Make sure that the electrical conductivity of the liquid is greater than 10 µ Siem.
• Many process liquids are designated by generic names. But these may contain certain
contaminants in traces. These traces may also be harmful to the Flowmeter. Therefore, check the compatibility of such traces as well.
• Note that the severity of corrosion of materials depends upon the temperature and the concentration of the process liquid.
• The corrosion due to service liquid will reduce the life of the Flowmeter.
b. Confirm that the available supply voltage and its frequency (for AC supply) are in
accordance with the specifications of the Flowmeter.
c. Ensure that the selected Flowmeter size is suitable for the flow rate to be measured.
Note that the velocity under normal conditions should be between 0.2 mis and 12 mis.
d. Confirm that an appropriate Earth pit is available for proper Grounding.

5 Sensor Installation

The Flowmeter can be installed at any arbitrary location in the pipeline as long as the installation requirements are satisfied. At the same time, care should be exercised when selecting the installation site to assure that moisture cannot enter into the connection area.
• A ball valve assembly with Weld Neck Flange will be supplied in advance.
• A hole of 1.96" diameter is to be made on the pipe line. The Weld Neck Flange is to be
welded into the Pipe Line for Flowmeter installation.
• Put a gasket between Weld neck Flange and Ball Valve Assembly.
• Mount Ball Valve Assembly on the Weld Neck Flange by aligning Weld Neck Flange and
Ball Valve Assembly Bottom Flange. Ensure Ball Valve Lever Alignment is with respected to the Flow direction as shown in the figure.
• The Ball Valve Assembly Mounting Bolts are provided (M 10 X 3.93") The mounting bolts are to be tightened. Follow diametrically opposite tightening Sequence.
• Loosen the Collet Clamping Screws provided on the periphery of collect at the Top of Ball Valve Assembly.
• According to the theory of velocity profiles for fully developed turbulent flow in the pipe line, the average velocity point is located at a distance of 1/8 D from the pipe wall where D is the internal pipe diameter.
• We insert up to 10% of Pipe Diameter.
• Before Sensor is inserted, the insertion length is marked on the Sensor.
a) Measure the length of Assembly from Pipe Surface to Collet Top. (Say X) b) Say Insertion Length is Y. c) Say Pipe Thickness is Z. d) Now mark the length of X + Y + Z starting from Electrodes and up.
• Now open Ball Valve lever fully. Slowly insert the Flow meter's Sensor, passing through the hole.
• Up to the length marked on the Sensor. The Flow Transmitter direction should be as per the drawing.
• Once, the Insertion Length is achieved, tighten the Collet Clamping Screws.
• For the Flowmeter installation in a pit, for proper installation, commissioning and
maintenance of the Flowmeter, the pit dimensions have to be at least 2 mtr X 2 mtr.
• Kindly ensure that the pit is covered with the protective cover. The pit should be waterproof so that in rainy season it should not get flooded or submerged in water.

Page 14

5.3 Flow Sensor Local Earthing / Grounding

a. A proper grounding of the Primary Head is very important to ensure proper functioning
and accurate measurement by the Flowmeter.
b. This ground is the reference ground for measurement and should not introduce any
interference into the signal to be measured. c. Use 0.098 inch² or higher conductor diameter cable for Earthing. d. To prevent any electrical interferences do not connect the ground of any other heavy
electrical equipment, to this ground. e. This ground also functions as the safety ground.

5.4 Checking for sealing

Once the Flow Sensor has been mounted, fill the pipeline gradually (preferably) with water instead of process liquid and confirm that the entire mounting is leak-free. If even minor leaks are noticed, check the axial alignment of the Flow Sensor with the upstream and downstream pipe lengths, cleanliness of gasket, the rating of gasket material and proper tightening of the bolts. After eliminating the leakages, allow the process liquid to pass through the pipeline.

12 Operational Precautions

a. The Junction Box of the Flow Sensor in case of a Remote Transmitter is designed for field
applications and use. However, it is advisable to protect it from exposure to direct sunlight and rain, by installing a weather shade over it. Likewise, the Transmitter is designed for field applications and use. However, it is advisable to protect it from exposure to direct sunlight and rain, by installing a weather shade over it. This will help extend the useful life of the Flowmeter as a whole.
b. Keep the covers of the Transmitter and that of the Junction Box well fastened, taking care
that the O-rings and Gaskets are undamaged and properly seated for effective sealing.
c. Keep the cable gland nuts tight and ensure that the cables are gripped uniformly around
their circumference to prevent any ingress of moisture or water into the Transmitter and Terminal Box.
d. Ensure that the Mains power supply is stable, without any surges & spikes and well within
the specified range.
e. Measure and ensure that there are no sources of strong magnetic field in the immediate
vicinity of the Flow Sensor. Such magnetic fields can interfere and alter the output signal of the Flowmeter.
f. Follow these steps to check that the zero flow condition is proper.
• Stop the flow through the Flow Sensor by shutting off the valve which is immediately downstream of the Flow Sensor.
• This way the Flow Sensor will remain filled with liquid.
• Keep the Transmitter powered ON.
• Measure the output signal using a calibrated 3½ digital multi meter.
• The output must be within 4±0.01 mA.
g. If the output is not within above values, the possible causes can be-
• Improper grounding.
• Shifted zero. In this case follow the Calibration mode.
• Contaminated electrodes.
h. Note that the pulsed-DC technique of exciting the field coils ensures a stable zero or auto
zeroing, provided all other requirements are satisfied.
i. The flowing liquid must be free of any gas bubbles as the presence of bubbles causes
falsified output.
