2. Structure and Operation Principle

2.1. Structure

KFL-DC series electromagnetic flowmeters are made up of sensor and transducer, together with

LCD screen, current and pulse output, alarm signal and RS-485 communication.

2.2 Operating Principle

Faraday’s Laws of Induction form the basis for the electromagnetic flowmeters. It states that a voltage is induced in a conductor as it moves through a magnetic field.

This principle is applied to a conductive fluid which flows through a magnetic field generated perpendicular to the flow direction

(see Schematic).

The voltage induced in the fluid is measured at two electrodes, installed diametrically opposed. This signal voltage U

E

is proportional to the magnetic induction B, the electrode spacing D and the average flow velocity v. Noting that the magnetic induction

B and the electrode spacing D are constants, a proportionality exists between the signal voltage UE and the average flow velocity v.

The equation for the volume flow shows that the signal voltage UE is linear and proportional to the volume flowrate. The

Fig. 1:

Electromagnetic Flowmeter Schematic induced signal voltage is processed in the converter into scaled, analog and digital signals.

Note 1: Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the instrument itself can be damaged and that fragments from the instrument can contaminate the user's process fluids. Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam

(150°C [302°F] or above). Contact KFL for detailed information of the wetted parts material.

7.3 Digital Data Output And Count

Digital output is frequency output and pulse output. Frequency output and pulse output use the same connection output point, therefore, users can only choice one of frequency output and pulse output at the same time.

7.3.1 Frequency Output:

The range of frequency output is 0 ~ 5000HZ and frequency output opposes percent flux.

F= (Measure value / Full scale value) · the range of frequency

The up limit of frequency output can be adjusted. It can be choice from 0 ~ 5000HZ, and also can be choice low frequency: such as 0 ~ 1000HZ or 0 ~ 5000HZ.

Frequency output mode general can be used in control application, because it responses the percent flux. Users can choice pulse output when the equipment is applied to count.

7.3.2 Pulse Output Mode:

Pulse output mainly applies in count mode. A pulse output delegates a unit flux, such as 1L or

1M3 etc. Pulse output unit divide into 0.001L, 0.01L, 0.1L, 1L, 0.001M3, 0.01M3, 0.1M3, 1 M3,

0.001UKG, 0.01UKG, 0.1UKG, 1UKG, 0.001USG, 0.01USG, 0.1USG, 1USG. When users choice the pulse unit, they should notice the match of the flux range of flowmeter and pulse unit. For volume flux, count formula as follows:

Note: D-nozzle (mm)

V-velocity of flow (m/s)

The oversize flux and too small pulse unit will be made the pulse output over the up limit.

Generally, pulse output should be controlled below 2000P/S. However, the too small flux and too large pulse unit will be made the instrument exports a pulse long time.

Otherwise, pulse output is different from frequency output. When pulse output cumulates a pulse unit, it exports a pulse. Therefore, pulse output is not equality. Generally, measure pulse output should choice count instrument, but not frequent instrument.

7.3.3 The Connection Of Digital Output

Digital output has three connected points: digital output connected point, digital ground point, and symbol as follows:

POUT ----- digital output point;

PCOM ----- digital ground point;

POUT is collector cut-off circuit output. Connect the line diagram as follows:

13. Installation

This section covers the steps required to physically install the flowtube. Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Please refer to the following safety messages before performing any operation in this section.

- 20 -

KFL ®

KFL-DC Series Electromagnetic Flowmeter

! WARNING

Failure to follow these installation guidelines could result in death or serious injury:

Installation and servicing instructions are for use by qualified personnel only. Performing any servicing other than that contained in this manual may result in death or serious injury. Do not perform any servicing other than that contained in the operating instructions, unless qualified.

! CAUTION

The flowtube liner is vulnerable to handling damage. Never place anything through the flowtube for the purpose of lifting or gaining leverage. Liner damage can render the flowtube useless.

! CAUTION

To avoid possible damage to the flowtube liner ends, do not use metallic or spiral-wound gaskets. If frequent removal is anticipated, take precautions to protect the liner ends.

Short spool pieces attached to the flowtube ends are often used for protection.

! CAUTION

Correct flange bolt tightening is crucial for proper flowtube operation and life. All bolts must be tightened in the proper sequence to the specified torque limits. Failure to observe these instructions could result in severe damage to the flowtube lining and possible flowtube replacement.

13.1. Upstream and Downstream Piping

To ensure specification accuracy over widely varying process conditions, install the flowtube a minimum of five straight pipe diameters upstream and two pipe diameters downstream from the electrode plane (see Fig. 10).

Fig. 10:

Upstream and Downstream Straight Pipe Diameters

13.2 Flowtube Orientation

The flowtube should be installed in a position that ensures the flowtube remains full during operation. Horizontal or inclined positions are preferred. Fig. 11, Fig 12, and Fig. 13 show the proper flowtube orientation for the most common installations. The following orientations ensure that the electrodes are in the optimum plane to minimize the effects of entrapped gas. As illustrated in Fig. 12B and Fig. 13B, avoid downward flows where back pressure does not ensure that the flowtube remains full at all times.

Incline or Decline Orientation

13.3 Flow Direction

The flowtube should be mounted so that the FORWARD end of the flow arrow, shown on the flowtube identification tag, points in the direction of flow through the tube (see Figure 2-6). In this mounting configuration, the conduit ports point upstream.

Fig. 14:

Flow Direction

13.4 Grounding

Grounding the flowtube is one of the most important details of flowtube installation. Proper grounding ensures that only the voltage induced in the magnetic field of the flowtube is measured.

Use Table 2-4 to determine which grounding option to follow for proper installation. Attached grounding rings should be grounded equivalently to non-attached grounding rings.

The flowtube case should always be grounded in accordance with national and local electrical

14. Troubleshooting

a) Check the power supply connection; b) Check the power fuse to see for OK; c) Check the contrast of LCD and regulate it to working state;

2) Exciting Alarm a) Check if the exciting cables EX1 and EX2 did not connected; b) Check if the total resistance of sensor’s exciting coil resistances less than 150 Ω ; c) If a) and b) are OK, the converter is failed.

3) Empty Pipe Alarm a) If measured fluid full of testing pipe of sensor; b) When shorting circuit three connectors SIG 1, SIG 2, SIGGND of converter, and no

“Empty Alarm” displayed then the converter works OK. In this case, it is possible that conductivity of measured fluid may be small or empty threshold of empty pipe and range of empty pipe are set wrongly. c) Check if the signal cable is OK; d) Check if the electro-poles are OK or not.

- Let the flow is zero, then the displayed conductivity should be less than 100%.

- Resistances of SIG1 to SIGGND and SIG2 to SIGGND are all less than 50k Ω

(conductivity of water) during measurement operation. (It is better to test the resistances by means of multimeter with pointer to see the charging process well.) e) The DC voltage should be less than 1V between DS1 and DS2 testing the voltage by means of multimeter. If DC voltage is larger than 1V, the electro poles of sensor were polluted that have to be cleaned.

4) Incorrect Measurement Of Flow a) Check if the fluid full of testing pipe; b) Check if the signal cable connection is right; c) Check if the sensor coefficient and zero settings are no deferent from the data on the labels of product that are calibrated by manufacturer.
