2 Product Description
This section covers the reference and specification data, as well as ordering information.
2.1 Introduction
Electromagnetic flowmeters 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 flowmeter 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 flowmeter 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 flowmeter 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)
www.GlobalTestSupply.com
07
Technology Solutions
Instruction Manual Tek-Flux 1400A
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

4.4 Connection of Cable
4.4.1 Output and Power Cable
All cables for signal transferring and for the power supply must be prepared by users. However, care must be taken to choose the cables that meet the upper limit load of consuming current. When the DIP switch next to the terminal is set to ON, the converter inside can provide +28V power supply and up-pull 10kΩ resistance to Output Frequencies (PUL) to isolated OC gate, Alarm Output (ALMH, ALML), and Status Control (INSW). Therefore, when the converter has a frequency output and works together with the sensor, the DIP switch can be set to ON, getting frequency signals from P transmitter, a diode should be used.

4.5 Digital Output
The transmitter has two output signals: frequency and pulse output. The user can choose only one type of output.
4.5.1 Frequency Output
Frequency output range is 0 to 5000Hz, and corresponding the percent of flux.

=
  
The upper limit of the frequency output can be adjusted from 0 to 5000 Hz; the lower frequency can be adjusted from 0 to 1000 Hz or 0 to 5000 Hz. The frequency output mode can be used in the control application, because it corresponds to the percent of flux. Users can choose pulse output when the equipment is applied to count mode.
4.5.2 Pulse Output Mode
The pulse output mainly applies in count mode. A pulse output delegates a unit flux, such as 1l or 1m3 etc. The pulse output unit divides into 0.001l, 0.01l, 0.1l, 1l,
0.001m3, 0.01m3, 0.1m3, 1m3. When users choose the pulse unit, the match of the flux range of flowmeter and pulse unit should be noted. For volume flux, the count formula is as follows:
×  
QL=0.0007854×D2×V (l/s)
or
QM=0.0007854×D2×V×10-3 (m3/s)
Note:
D is the diameter of the nozzle (mm) V is the velocity of flow (m/s)

• Current Zero is Correct When the converter is in parameter setting, select to “Analog Zero” and press enter. The standard of signal fountain is set to “0.”. Adjust the parameter and make sure the ampere meter is 4 mA (±0.004 mA).
• The Full-Scale Current is Correct Select “Analog Range” to enter. Adjust the converter parameter and make sure the ampere meter is 20 mA (±0.004 mA). Adjust the current between zero and full range, the current function of the converter should reach exactness. The line degree of the current output of conversion should be controlled within the scope of 0.1%.
• Current Line Degree Checking You can place the standard signal source at 75%, 50%, 25%, and check the line degree of current output.

6 Troubleshooting
This section provides troubleshooting techniques for most common operating problems.
6.1 No Display
1. Check the power supply connection
2. Check the power fuse for faults
3. Check the contrast of LCD and adjust
6.2 Exciting Alarm
1. Check the connection of the exciting cables
2. Check the total resistance of sensor’s exciting coil resistances (less than 150Ω)
3. If first and second points are OK, then the converter is faulty
6.3 Empty Pipe Alarm
If measured fluid full of testing pipe of sensor:
1. Short circuit three connectors SIG 1, SIG 2, SGND of converter; if no “Empty Alarm” is displayed then the converter works. In this case, it is possible that the conductivity of measured fluid may be limited or the empty threshold of the empty pipe and the range of the empty pipe are incorrectly set
2. Check if the signal cable is OK
3. Check if the electro-poles are OK or not
4. Let the flow be zero, then the displayed conductivity should be less than 100%
5. Resistances of SIG1 to SGND and SIG2 to SGND are all less than 50kΩ (conductivity of water) during measurement operation. (It is better to test the resistances by means of multi-meter with pointer to see the charging process well
6.4 Measure Flow Disallow
If measured fluid full of testing pipe of sensor, check if the signal cable is OK.
