(1) Do not store or install the flowmeter in: Where there is direct sunlight. Where there is snow and ice Infrared switches may not function correctly. Where excessive vibration or mechanical shock occurs. Where high temperature or high humidity conditions obtain. Where corrosive atmospheres exist. That can be submerged under water. Where there is a sloped floor. To put the flowmeter temporarily on the floor, place it carefully with something, such as a block, to support it so that the flowmeter will not topple over. Places where there is following factors. Factors to impede infrared switch to operate properly Intense light such as direct sunlight and reflected sunlight by window glass or metal plate Place where brightness changes suddenly such as ON/OFF of lighting Dense smoke or steam near the control panel Those attached on the control panel such as rain (dew drop), snow, ice, mud and oil, and haze due to their attachment Light reflecting object near the control panel, or reflecting object such as metal plate placed opposing to the control panel When any of above factors is considered, take a measure for the proper operation of infrared switch such as to place a cover or to secure a space for at least a person to stand in front of the control panel. When unable to avoid above factors, operate the EMF converter removing the factor by covering the control panel by hand so that light does not shine on it, by cleaning those attached on the control panel, or by standing in-between the reflecting object and the control panel to block the light. (2) In the case that the piping is non-conductive material, make sure to install the grounding rings(option) to each flange of detector using the M3 or M4 screw before piping. (3) Wire cables correctly and securely. Be sure to ground at the converter side (grounding resistance 100 ohm or less). Avoid a common ground used with other equipment where earth current may flow. An independent ground is preferable (4) Select cable paths away from electrical equipment (motors, transformers, or radio transmitters), which causes electromagnetic or electrostatic interference. (5) The apparatus does not be provided with the cable connections. Please prepare yourself for the cable connections which could be used in Division2 hazardous locations. The cable lead-in section must be tightened securely to keep air tightness. - 6 - 6F8A0883 Handling Precautions (continued) (6) If the inside of the converter and detector's terminal box are wetted or humidified, it may cause insulation deterioration, which can result in fault or noise occurrence. So do not conduct wiring in the open air on rainy days. Also, be careful not to wet down the converter and detector's terminal box even in the case of indoor wiring, and complete wiring work in a short period of time. (7) Make sure the fluid to be measured will not freeze in the detector pipe. This can cause damage to the detector pipe. (8) Select appropriate wetted materials suited for the process fluid to be measured. Otherwise, fluid leakage due to corrosion can be caused. (9) Observe the following precautions when you open the converter housing cover: • Do not open the cover in the open air unprotected against rain or wind. This can cause electric shock or cause damage to the flowmeter electronics. Do not open the cover under high ambient temperature or high humidity conditions or in corrosive atmospheres. This can cause deterioration of system accuracy or cause damage to the flowmeter electronics. (10) Since a varistor is built in converter, do not conduct a withstand voltage test for the converter. In addition, the voltage for checking the insulation of the converter must be 250VDC or lower. (11) This product may cause interference to radio and television sets if they are used near the installation site. Use metal conduits etc. for cables to prevent this interference. (12) Radio transmitters such as transceivers or cellular phones may cause interference to the flowmeter if they are used near the installation site. Observe the following precautions when using them: • Close a transmitter cover before using a transceiver. • Do not use a transceiver whose output power is more than 5 W. • Move the antenna of a transceiver or a cellular phone at least 50 cm away from the flowmeter and signal cables when using it. • Do not use a radio transmitter or a cellular phone near the flowmeter while it is operating online. The transmitter or cellular phone’s output impulse noise may interfere with the flowmeter. • Do not install a radio transmitter antenna near the flowmeter and signal cables. (13) For reasons of flowmeter failure, inappropriate parameters, unsuitable cable connections or poor installation conditions, the flowmeter may not operate properly. To prevent any of these problems causing a system failure, it is recommended that you have preventive measures designed and installed on the flowmeter signal receiving side. (14) For installation and connectirn of the converter, check the model number of converter and read the instruction manual of the relevant converter. * We assume no responsibility for nonconformity caused by violation of precautions described in this manual or used in violation of the installation method and the operation method stipulated in a relevant ordinance or other regulations.

- 16 - 6F8A0883 4.1 Notes on Selecting the Installation Location 1. Avoid places within the immediate proximity of equipment producing electrical interference (such as motors, transformers, radio transmitters, electrolytic cells, or other equipment causing electromagnetic or electrostatic interference). 2. Avoid places where excessive pipe vibration occurs. 3. Avoid places where fluid is pumped in a pulsating manner 4. Avoid places where there is direct sunlight. If this is unavoidable, use an appropriate shade 5. Avoid places where corrosive atmospheres or high humidity conditions obtain. 6. Avoid places where there may be limited access such as pipes installed next to high ceilings or constricted areas where clearance for installation or maintenance work is not provided. 7. Design piping so that the detector pipe is always filled with fluid, whether the fluid is flowing or not. 8. The detector has no adjustable piping mechanism. Install an adjustable short pipe where needed. 9. Chemical injections should be conducted on the downstream side of the flowmeter.

Separate 10. The maximum length of the cable that connects the detector and converter is 300m. Select the converter installation location so that the distance between the detector and converter dose not exceed 300m.

4.2 Mounting Procedure 4.2.1 Pipe checks (1) Before installing pipes, check for any leaning, misplacement or eccentricity as illustrated in Figure 4.1. An attempt to unreasonably connect pipes that are inclined may lead to a detector breakdown or fluid leakage. Connecting pipes in an eccentric state may also cause wears and tear of linings and grounding rings, as well as measurement errors. Before installing pipes, make sure to flush the interior of the pipes to remove deposited material. (a) Pipe leaning (b) Pipe axis misplacement (or eccentricity) Eccentricity Inclination Figure 4.1 Pipe leaning and axis misplacement - 17 - 6F8A0883 (2) Preventing an Empty Pipe Condition Fix the relevant pipes installed on both sides of the detector by attaching fittings, etc. to support the pipe. By supporting the pipes, not only the pipe vibration is reduced but also the damage to the pipes by the electromagnetic flowmeter's weight and the fluid mass (see Figures 4.2 and 4.3). Pipe support fittings Pipe support fittingsFigure 4.2 Example of Pipe Fixing Procedure Figure 4.3 Model Diagram of Unsupported Pipes - 18 - 6F8A0883 4.2.2 Installation Procedure In the case that the piping is non-conductive material, make sure to install the grounding rings(option) to each flange of detector using the M4 screw before piping . The M4 screws are prepared to each flange. In addition, in the case of detector with FEP lining, make sure to install the gaskets between grounding ring and lining. The gaskets must be installed so as not to protrude into the measurement tube. And install the ground cables to each flange of detector using the M5 screw as needed. The M5 screws, spring washers and washers are prepared to flange. And the ground cables are included in the package.

See Figure 4.5 and follow the procedure below: 1. Insert two lower mounting bolts through the clearance holes in the upstream (or downstream) pipe flange. 2. Install a gasket next to the upstream (or downstream) flange face and the other gasket next to the downstream (or upstream) pipe flange. The two mounting bolts can now be guided through the clearance holes in the downstream gasket and flange. 3. Place the GF630 series flowmeter detector between the two flange gasket, with the flowmeter detector body above the two bolts. The flowmeter must be oriented in accordance with the flow direction arrow. 4. Install the two upper mounting bolts through the clearance holes in the upstream and downstream gasket and flanges. Then install the remaining mounting bolts depending on the flange pattern used. 5. Thread nuts on both ends of the 4 (or more) mounting bolts, finger tight. (See Table 4.1 Bolt length and tightening torque) 6. While centering the flowmeter with the longitudinal axis of the pipeline, tighten the nuts with a wrench diagonally across in even increments. (See Table 4.1 Bolt length and tightening torque) Note1: The flowmeter detector pipe axis must be aligned with the pipeline axis on both upstream and downstream sides. This is essential to have stable characteristics of flow measurement (especially for flowmeters with meter sizes of 2"(50 mm) or less). Note2: In the case of detector with CR or PU lining, please avoid use of a gasket that is same materials with lining material. If the same materials were used, gasket and lining would bond mutually. CAUTION (1) When high-temperature fluid is being measured, radiant heat from the detector pipe surface and adjoining pipes may cause the ambient temperature of the converter to go above 60 C (140 F). If the ambient temperature goes above 60 C (140 F), try to lower the temperature by measures such as wrapping heat-insulating materials over the detector pipe and adjoining pipes.

Separate 6F8A0883 Notes on wiring CAUTION (1) The apparatus does not be provided with the cable connections. Please prepare yourself for the cable connections which could be used in Division2 hazardous locations. The cable lead –in section must be tightened securely to keep air tightness. (2) Select the cable runs away from electrical equipment (motors, transformers, or radio transmitters) which causes electromagnetic or electrostatic interference. (3) Deterioration of flowmeter circuit insulation occurs if the converter interior or cable ends get wet or humidified. This in turn causes malfunction of flowmeter or noise problems. Avoid a rainy day if the flowmeter is to be installed outdoors. Even indoors, prevent water from splashing over the flowmeter. Try to finish the wiring as quickly as possible (4) The converter has an arrestor installed inside. Therefore, do not conduct a withstand voltage test for the converter. To check the insulation of the converter, use a voltage of 250Vdc or less. (5) After wiring, be sure to install the terminal block protection cover. (6) Because the excitation cable and flow rate signal cable transmit very delicate signals, pass each of them separately through a thick steel conduit tube, keep them away from the large current wiring as far as possible, and do not install them in parallel.

- 40 - 6F8A0883 8. Principle of Operation The operating principle of the electromagnetic flowmeter is based on Faraday's Law of electromagnetic induction and it is designed to measure the volumetric flow rate of fluid. An insulated pipe of diameter D is placed vertically to the direction of a magnetic field with flux density B (see Figure 8.1). When an electrically conductive fluid flowsin the pipe, an electrode voltage E isinduced between a pair of electrodes placed at right angles to the direction of magnetic field. The electrode voltage E is directly proportional to the average fluid velocity V. The following expression is applicable to the voltage.

E = K × B × D × V [V] ........ (Eq. 8.1) Volumetric flow rate Q [m3/s] is: × D² Q = × V ................(Eq. 8.2) 4 Using the Equation 8.1 and 8.2 4 E = K × B × D × × Q × D² 4 × K × B E = × Q ............(Eq. 8.3) × D E = induced electrode voltage [V] K = constant B = magnetic flux density [T] D = meter pipe diameter [m] V = fluid velocity [m/s]

Therefore, volumetric flow rate is directly proportional to the induced voltage. Square-Wave Excitation E V

The GF630/LF600F, GF630/LF610F, GF630/LF620F and GF632 use the square-wave excitation method, which provides long-term stable operation. With square-wave excitation, the GF630/LF600F, GF630/LF610F, GF630/LF620F and GF632 offers reliable measurement without being affected by electrostatic or electromagnetic interference, or electrochemical polarization between the electrodes and the fluid to be measured. - 41 - 6F8A0883 9.
