Azbil Corporation No. SS2-MTG300-0300 - 7 - . Fluids that have sufficient conductivity at high temperature but do not meet the conductivity requirement at room temperature (about 20oC (68oF)). (e.g. fatty acids and soap) . Some fluids contain surfactant (e.g. rinse, shampoo and CWM (coal water mixture)) . Insulating adhesive materials (e.g. kaolinite, kaolin, calcium stearate) . The analog output may fluctuate due to flow noise, which is generated by the process fluid flow. In such a case, connect the upstream grounding ring to the downstream grounding ring by a wire. The output fluctuation may be reduced. Caution On PLC Connection . A circuit in some PLC may affect the flow measurement and the analog output may fluctuate. In this case, make sure that the both PLC and the MagneW Two-wire PLUS+ flowmeter are properly grounded. Proper grounding solves the fluctuation problem. Notice for power supply . Use the following power supply. If the power supply does not meet the following specifications, this device may not work. . Current capacity: 24mA min.  CAUTION In accordance with the safety standards of flameproof regulation, please comply with the following instructions.: (1) The voltage of general equipment such as the power supply and the receiver should not exceed 250VAC, 50/60Hz, 250VDC at any time at normal or abnormal operation. (2) The ambient temperature around the device is 50oC (122oF) maximum. (3) The process fluid temperature is 125oC (257oF) max. for the size of 15mm (1/2 inch) or larger. (4) The process fluid temperature is 100oC (212oF) max. for the size of 10mm (3/8 inch) or smaller. (5) Use the specified flameproof cable glands. (6) Wait for seven minutes after switching OFF the power supply, before opening the front cover or the terminal cover. A specified explosion-proof performance is available only when this device is used under the conditions described above. 4 12
