IMPORTANT

Improper grounding can have an adverse affect on the flow measurement. Please ensure that the instrument is properly grounded.

The electromotive force of the magnetic flowmeter is minute and it is easy to be affected by noise. And also that reference electric potential is the same as the measuring fluid potential. Therefore, the reference electric potential (terminal potential) of the Flow Tube and the Converter/Amplifier also need to be the same as the measuring fluid. And moreover, that the potential must be the same with ground.

Please be sure to grounding according to Figure 4.1.7.

A Magnetic flowmeter calculates volume flow rate from a minute voltage that corresponds to the flow velocity of a fluid an outputs as a 4 to 20mA signal.

The three parameters must be set to obtain a correct signal.

NOTE

Nominal size, flow span and meter factor must be set. In these three factors, Nominal size (unit:mm) and meter factor are set before shipment.

This chapter explaines how to set flow span, other functions and data settings. Please set data correctly.

• you cannot set the leftmost digit of display to numeric value

greater than "4". If the leftmost digit of the span must be "4| or more, set the numeric value beginning from the digit second from the left on the display (the fourth digit).

• If the leftmost digit of the display is set to "3", the digits to its right can be set to "0" only, regardless of the decimal point position

6. FUNCTION AND DATA SETTINGS

6.1 Flow Rate Span Setting

(1) Determining the Flow Rate Span Value

The flow rate span is the instantaneous flow rate value at which the output current is to be 20 mA.

Please determine the span under considering the followings.

•Please set the maximum flow rate at the most variable flow rate line. If the flow rate of the fluid exceeds the flow rate span value, the flow rate that exceeds this value (20mA or more) is not output and the flowmeter will not display the correct flow rate. (108% or more can't be output)

• In a line where the flow rate is comparatively stable, set a value that is 1.5 to 2.0 times larger than the normal flow rate.

• Please set a value that will correspond to a flow velocity of 0.5 to 10m/s.

Please comfirm the flow velocity by sizing data or parameter No. “13”. (Parameter No. “13” indicates corresponding flow velocity to set span)

• The basic input value for display is flow span value. It is recommended that the accuracy of the first digit is in a 0.05 to 0.1% in case inputting the flow rate span value. For example, 30m

•In a span setting, the maximum value that can set is “30000” except any relation with decimal position.

/h should be set as 30.00m3/h.

6.2 Measuring Mode Setting

(1) Measuring Modes

The measuring mode is Standard or Noise Reduction mode. Standard mode is set before shipment. If the output fluctuation is large when a fluid actually flows, the fluctuation is reduced by increasing the damping time constant.

• If the output fluctuation is still large when the damping time constant is increased, use the Noise Reduction mode.

• Use the standard mode for sticky fluids.

After the measuring mode is changed from Standard mode to Noise Reduction mode or from Noise Reduction mode to Standard mode, be sure to adjust the zero point. Perform zero adjustment with the metering tube filled with the fluid and with the fluid static.

6. FUNCTION AND DATA SETTINGS

7. OPERATION VIA BRAIN TERMINAL

Products provided with optional code / BR come equipped with a BRAIN communication function which allows them to communicate with dedicated brain terminals (BT) or CENTUM-XL / CS. In the BRAIN - Series communications system, a +2 mA, 2.4 kHz modulated signal is superimposed onto the 4 to 20 mA DC analog signal for data transmission. Since the modulated wave is an AC signal, superimposing it on the analog signal will cause no error in the DC component of the analog signal. Thus, monitoring can be performed via communications while the ADMAG CA is online.

A BT200 can be connected to the terminals shown in Figure 7.1 on products that are not provided with a / BR (brain communication function).

7.1 Operation Via the BT200

This section describes the operation procedures using a brain terminal. For details on the functions of the ADMAG CA, see Chapter 6, "Function and Data Settings." And also, see the "BT200 Instruction Manual" (IM IC0A11-01E) for more detailed information.

8. ACTUAL OPERATION

After you have installed the flowtube into the process piping, wired the input / output functions, set up the required converter parameters, and performed the pre-operation zero adjustment, the magnetic flowmeter should output an accurate flow signal from its terminals as soon as the measured liquid begins to flow.

This section describes procedures of zero adjustment and alarms countermeasure.

8.1 Pre-Operation Zero Adjustment

In the magnetic flowmeter, zero adjustment is required before beginning operation in order to obtain a 4 to 20mA signal that is accurately proportional to the flow.

This section describes two procedures for performing zero adjustment. Using the data setting keys on the converter front panel or using a BT200. Zero adjustment is made to set the instrument output to 0% (4mA) when the flow rate is

0. The detector must be filled with fluid and let it stand until all motion has ceased.

8. ACTUAL OPERATION

IMPORTANT

1. Zero adjustment should be done only when the fluid is filled in the flow

tube and the fluid velocity is completely zero by closing the valve.

2. Zero adjustment should be done prior to the other operation. For 60

seconds during the zero adjustment, any setting cannot be accepted.

3. As warming up time for converter, please wait 5 min. for size 15 to 100

mm (0.5 to 4 in) or 10 min. for size 150, 200 mm (6, 8 in) before zero adjustment after the power is turned on.

8. ACTUAL OPERATION

8.2 Self-diagnostics Functions

• The self-diagnostic function displays instrument internal errors, input/output signal abnormalities, setting errors, and other problems.

• When an alarm occurs, an alarm number announcing that an error has occurred is superimposed on the normal data display.

However, alarms are only displayed during normal flow rate data display mode and

when parameter numbers are changed in the setting mode. (Alarms are not displayed when data items are being changed.)

• When the BT200 is used, alarms are displayed in the A to N60 SELF CHECK parameter. If an error is detected and ERROR appears in the display, investigate the nature of the error.

8.2.1 Display and Output Status during Alarm occurrence

• If an error occurs, the panel display LED flashes and an alarm number is superimposed on the normal display. During this time the current output is fixed to

2.4mA max., 4mA, HOLD or 21.6mA max., as selected in 4-20 ALM OUT (output current during alarm).

•An alarm (status contact output) is output for any of the errors indicated in the table at right.

11. OPERATING PRINCIPLE

11.1 Principle of Magnetic Flowmeter Operation

The operating principle of the magnetic flowmeter is based on the law of electromagnetic induction which states that when a conductor moves in a magnetic field, in the direction perpendicular to the magnetic field, an electromotive force is induced perpendicular to the direction of the conductor movement and to the direction of the magnetic field. The value of the electromotive force is proportional to the conductor velocity and magnetic flux density.

In Figure 11.1, when a conductive fluid flows at an average velocity of V (m/s) through a pipe whose inner diameter is D (m), in which a magnetic field of uniform flux density B (tesla) exists, an electromotive force E (volts) is induced perpendicular to the direction of the magnetic field and to the flow.

E=D⋅V⋅B V

................. (1)

The volumetric flowrate Q is obtained from the following equation.

⋅D2⋅V m3/s

...... (2)

From equations (1) and (2), the next equation is obtained.

⋅Ε

m3/s

⋅

....... (3)

Therefore, the electromotive force E is expressed as shown below.

⋅

⋅Q V

............. (4)

If B is constant, then Q will be proportional to E from equation (3). The magnetic flow converter amplifies and converts this electromotive force E to a

standard signal of 4 to 20 mA or a pulse signal.

11. OPERATING PRINCIPLE

11.2 Principal and Features of the capacitance Magnetic flowmeter

The measuring principle of the capacitance magnetic flowmeter (ADMAG CA) is basically the same as that of a conventional wetted-electrode magnetic flowmeter. The capacitance magnetic flowmeter, however, picks up the e.m.f. signal generated in a liquid through the ceramic tube wall's capacitance by placing both electrodes outside the metering tube (ceramic tube) making them non-wetted.

The ADMAG CA can offer stable measurement by taking the following measures against fluid noise ( slurry noise and flow noise) which are problematic in flow measurement by magnetic flowmeters.

(1) Slurry Noise

Slurry noise is the noise generated when solid matter in a fluid collides with the electrodes. Against this noise, stable measurement is realized by employing a capacitance detection construction in which the electrodes are not wetted.

(2) Flow Noise

Flow noise voltages generated when measuring low-conductivity fluids have the characteristic, the higher the frequency, the smaller the noise voltage. The ADMAG CA provides the flow measurement of fluids having a very low conductivity by adopting a high-frequency excitation affected less by flow noise and by taking zero-stability measures by improving the magnetic circuit and employing capacitance electrodes.

11.3 Capacitance Magnetic flowmeter circuit Configuration

(1) Circuit Configuration

A capacitance magnetic flowmeter differs from a wetted-electrode magnetic flowmeter in forming area electrodes outside the metering tube. The magnetic flow detector consists of a ceramic tube, capacitance electrodes formed outside the ceramic tube, a magnetic circuit including excitation coils and a core, earth rings and shield cases.

Since electrode impedances are extremely high for capacitance electrodes, driven shield is implemented for capacitance electrodes by providing shield cases in the form of enclosing the capacitance electrodes to prevent the effect of stray capacitance.

The converter is composed of the exciting circuit for dual square wave frequency excitation, an amplify circuit to amplify the e. m. f. generated between capacitance electrodes and digital circuit including an A/D converter and timing circuits.

POWER

• Power supply (switching regulator system) The switching regulator system is a power circuit unique to Yokogawa. Supply

Voltage changes do not affect the converters Yokogawa. Supply voltage changes do not affect the converters operation because this system not only can be driven by either AC or DC power but also continuously controls the secondary voltage.

• Excitation system and signal conditioning There is a problem with an unstable zero point in high-frequency excitation that is

less affected by fluid noise. To resolve this problem, it is necessary to make the rise of magnetic field faster and have the magnetic field remain constant during signal sampling. The ADMAG CA stabilizes the zero point by adopting capacitance electrodes and improving.

The signal allows the stable measurement of fluids whose conductivity is very low or

fluids which are stick because the signal is less affected by flow noise.

•Functions Soft ware engineering actively utilizes the capability of microcomputers to its maxi-

mum. The converter is provided with various functions such as span setting in an engineering unit, totalization, pulse output, self-diagnosis and others as well as active use of microcomputer for excitation and signal conditioning.
