Introduction

The electromagnetic flowmeter uses Faraday???s Law of electromagnetic induction to measure the process flow. The device consists of two units: a detector, through which the fluid to be measured flows and in which low-level signals proportional to flow rates are obtained; and a converter, which supplies excitation current to the detector, and amplifies the signals from the detector and then processes and converts the signals into the 4???20mAdc current signal or communication signal. Thanks to the unique patented magnetic field distribution technology, the meter is highly immune for upstream flow disturbances. Combined with multi-functional converter LF600 (combined type) or LF602 (separate type) equipped with its original noise-suppression circuit and arithmetic operation capability, LF410 has high tolerance to noise, giving stable output even for slurry fluid measurement. IR (Infrared) switches enable parameter setting of the converter without removing the cover. Flow direction can be set in either way, and its 128 x 128 dot matrix LCD display allows the LCD rotated to 90, 180 and 270 degrees with a software.

Specifications

Overall Specifications

The AF900 hand-held terminal (HART*1 communicator) can be used to communicate with the flowmeter from a remote place. PROFIBUS-PA*2 interface is available as option.

*1: HART protocol (Highway Addressable Remote Transducer) is a communication protocol for industrial sensors recommended by the HCF (HART Communication Foundation).

*2: PROFIBUS is the communication protocol for the factory automation and process automation that PROFIBUS Organization recommends. Instead of analog control with a conventional analog signal (4-20mA), it is one kind of the fieldbus which digitized all signals. Flowmeters support PROFIBUS-PA.

Measurement range in terms of flow velocity:

0 ??? 0.3 m/s to 0 ???10 m/s (0 ???1.0 ft/s to 0 ??? 32.8 ft/s). 0 ??? 0.1 m/s to 0 ??? 0.3 m/s (0 ??? 0.3 ft/s to 0 ??? 1.0 ft/s) range is available optionally.

Cable ground

Wiring Precautions

(1)Explosion proof type flowmeters are not provided cable glands.

Refer to the part Cable connection port at detector and converter.

(2)Connect the grounding wire (IV wire 5.5mm?? or more) to a good earth ground (100?? or less ground resistance). Make the wire as short as possible. Do not use a common ground shared with other equipment where earth current may flow. An independent earth ground is recommended.

(3)The allowable cable lengths between the detector and converter for the separate type flowmeter depend on the electrical conductivity of the object fluid. See Figure 12 below.

(4)DO1, DO2 (opt.), and DI (opt.) use the same common terminal (COM). This COM can not connect to other equipments which have their own ground terminal.

(Power supply for connecting to DI or DO, etc???) Need to wire separately.

Wiring Precautions (PROFIBUS)

(1)For wiring path, avoid places near electrical equipment that may cause electromagnetic induction or electrostatic induction interference (such as a motor, transformer and wireless transmitter).

(2)Use a PROFIBUS-PA cable for signal cable. In addition, make sure to use a shielded cable to improve noise resistance. Furthermore, installation of signal cable in metal conduit is recommended.

(3)General PROFIBUS-PA cables are designed for indoor use where cables are not exposed to humidity, rain, etc. When you install cables, make sure to check the operating conditions such as the operating temperature range of the cable by contacting its manufacturer.

(4)When you carry out cable end treatment of PROFIBUS-PA cable, use a dedicated cable stripper etc. so that the core wire of the cable will not be nicked or damaged. In addition, for cables, be careful of allowable maximum bend diameter etc. (Basically, do not install cables in a way cables are twisted or bent.).

(5)Consider installing a PROFIBUS-PA arrester in the communication path of PROFBUS-PA so that the electromagnetic flowmeter will not be affected by lightning etc.

(6)The electromagnetic flowmeter is not equipped with terminating resistors.Use the terminating resistor unit for PROFIBUS-PA or junction box, if necessary.

(7)Only one PROFIBUS-PA cable goes through a cable gland of the Electromagnetic Flowmeter. Please use the junction box at system configuration.

Figure 12. Electrical Conductivity and

Cable Length

Piping Precautions

(1) Design piping so that the flowmeter detector pipe is always filled with the fluid being measured,

whether the fluid is flowing or not.

(2)The detector has no adjustable piping mechanism. Install an adjustable short pipe where needed.

(3) The required straight pipe length should comply

with the requirements as follows.

(4) Be sure to grounding the flowmeter according to below figure.

Meter Size

To select the meter size:

See Figure 13 and find meter sizes within the velocity of 0.1 to 10m/s for a specified full-scale (measuring range high limit) flow. Select one that has its full-scale velocity between 1 and 3m/s.

Note: Make sure the full-scale flow rate used for the final planning stage stays within 10m/s in terms of flow velocity.

Flow velocity (m/s)

Flow rate (m3/h)

Figure 13. Flow Rate and Flow Velocity

Calibration Range

If the calibration range is not specified, the standard range as shown below will be used. If the range is specified, we will use the specified range for calibration.

Note: The unit of "gal/min" is not exchanged (converted) by "m3/h".

PED matrix in each flange connection.

The following sizes fall under the category for PED in each flange connection when the meter ships to EU. All of them had complied with it from a notified body.

Table 2 PED matrix in each flange connection

About establishment environment

Do not store or install the flowmeter in:

???Places where there is direct sunlight.

???Places where excessive vibration or mechanical shock occurs.

???Places where high temperature or high humidity conditions obtain.

???Places where corrosive atmospheres obtain.

???Places submerged under water.

???Place where there is slop floor. To put the flowmeter temporarily on the floor, place it carefully with something, such as stopper, to support it so that the flowmeter will not topple over.

In places like the following places, there is the case that infrared switches do not function correctly. (If this is unavoidable, use an appropriate cover.

???Places where gets very bright light onto operation panel. (direct sunlight, reflection light of sunlight by windowpanes, diffused reflection light of strength etc.)

???Places where smoke and steam occur near.

???Places where a snow, ice or mud that may attached.
