Azbil Corporation No. SS2-MTG300-0100 - 7 - Notice for installation To fully enjoy the performance of the device, please choose an appropriate location according to the following. Notice after installation  WARNING When removing the device from the piping, make sure that there is no line pressure or process fluid inside of the device. Removing the device before depressurizing may result in serious injury.  CAUTION Do not use the device as a foothold. It may cause injury or damage of the device. Notice for environment . Install the flowmeter in a location with an ambient temperature of -25°C to 60°C (-13°F to 140°F) and an ambient humidity of 5 to 100%RH to prevent equipment malfunction or output errors. . Do not install the flowmeter in a location subject to severe vibration or in a highly corrosive atmosphere. The converter and detector can be damaged. * When install some electromagnetic flowmeters in closer location, keep minimum 500mm (20 inch) space from each flowmeter. Closer electromagnetic flowmeter installation may cause magnetic interference each other and results in output errors. . Do not install the flowmeter in a location subject to severe vibration or in a highly corrosive atmosphere. The converter and detector can be damaged. . When install some electromagnetic flowmeters in closer location, keep minimum 500mm (20 inch) space from each flowmeter. Closer electromagnetic flowmeter installation may cause magnetic interference each other and results in output errors. Notice for application . Electrolytic bath application, process fluid with higher voltage/current Process fluid of the electrolytic bath application is mostly with high voltage/current. It is not a suitable application for the two wire loop powered magnetic flowmeter. Example: Sodium hypochlorite with 200V and 30kA Four wire magnetic flowmeter is recommended. . Application which pipe frequently becomes empty Both two wire magnetic flowmeter and four wire magnetic flowmeter have empty pipe detection function. The two wire magnetic flowmeter detects empty by monitoring signal fluctuation caused by empty pipe condition. Therefore the empty pipe detection function of the two wire magnetic flowmeter sometimes does not work properly if noise level is too low or too high. The four wire magnetic flowmeter detects empty by monitoring impedance between electrodes and grounding. So the four wire magnetic flowmeter directly monitors the empty pipe condition. If the application requires empty detection quickly and perfectly, the four wire magnetic flowmeter is recommended. . Plastic piping or piping with liner If the customer piping is plastic or lined with insulation material, process fluid may not be properly grounded. In such case, it is recommended to connect earth wire between upstream side grounding ring and downstream side grounding ring for better grounding. . Slurry application Process fluid with slurry exceeds 3% is not suitable for the two wire magnetic flowmeter. The four wire magnetic flowmeter is recommended for the fluid with slurry concentration more than 3%. If hard particles hit the electrode, output of the two wire magnetic flowmeter may fluctuate even though the slurry concentration is less than 3%. In this case, the four wire magnetic flowmeter is recommended. . Electrochemically homogeneous fluid Install the device where the process fluid is electrochemically homogeneous. If two kind of process fluids are mixed at the upstream side, the process fluid must be uniformly mixed. . The application which the electric conductivity changes or non-homogeneous fluid Do not use the device for the following fluid conditions even if the electric conductivity, temperature, and pressure are within the device specifica- 4 11
