If theinstructions contained within it are not followed, in particular the safety guidelines, this couldresult in danger for people, the environment, and the device and the system it is connected to.The FMG90B corresponds to the state-of-the-art technology. This concerns the accuracy, the operating mode and the safe operation of the device.In order to guarantee that the device operates safely, the operator must act competently andbe conscious of safety issues.OMEGA provides support for the use of its products either personally or via relevant literature. The customer verifies that our product is fit for purpose based on our technical information. The customer performs customer- and application-specific tests to ensure that the product is suitable for the intended use. With this verification all hazards and risks aretransferred to our customers; our warranty is not valid. Qualified personnel:The personnel who are charged for the installation, operation and maintenance of theFMG90B must hold a relevant qualification. This can be based on training or relevanttuition.The personnel must be aware of this operating manual and have access to it at all times.The electrical connection should only be carried out by a fully qualified electrician. General safety instructions:In all work, the existing national regulations for accident prevention and safety in theworkplace must be complied with. Any internal regulations of the operator must also becomplied with, even if these are not mentioned in this manual. Degree of protection according to EN 60529:Please ensure that the ambient conditions at the site of use does not exceed the requirements for the stated protection rating (§ 9 "Technical data"). Prevent freezing of the medium in the device with appropriate measures.Only use the FMG90B if it is in perfect condition. Damaged or faulty devices must be checked without delay and, if necessary, replaced.When fitting, connecting and removing use only suitable appropriate tools.Do not remove or obliterate type plates or other markings on the device, as otherwise thewarranty is rendered null and void. Special safety instructions:Crystallizing liquids:Liquids which crystallize when dried out can cause a malfunction of the FMG90B. Make sure that the FMG90B is not run dry.Prevent the crystallization of the fluid in the device by taking appropriate measures.Further warnings that are specifically relevant to individual operating procedures or activities can be found at the beginning of the relevant sections of this operating manual.Construction and function FMG90B Series- 8 -3 Construction and functionComponents:① Housing:The Housing consists of plastic and has the IP65 degree of protection.② Electrical connection:The electrical connection is made via 4-pin plug M12x1.③ Operation / flow indicator LED.④ Process connection:The process connections are available in different sizes.Construction:The measuring tube with its grounding sleeves and electrodes passes through the housing and forms the external process connection of the FMG90B.A magnetic field for the measurement process is generated inside the housing, which also contains the sensor and signal conditioning circuitry.The two stainless steel electrodes are located in the middle of the measuring tube between the grounding sleeves.The FMG90B does not need any moving parts to make measurements. The inside of the measuring tube is completely open, allowing the fluid to flow unhindered through the measuring tube.Function:The magnetic inductive flow sensor functions according to the induction principle. A DC voltage is generated by the movement of a conductor in a magnetic field:The measuring tube of the FMG90B is located in a magnetic field (B).An electrically conductive medium (V) flows through the measuring tube. The positive and negative charge carriers are oppositely deflected.A voltage (U) is generated at right angles to the magnetic field, which is picked up by the two electrodes.Thereby, the induced voltage is proportional to the average flow velocity of the liquid.The electronics of the FMG90B converts the induced voltage into a flow-proportional frequency signal.FMG90B Series Installation of FMG90BTechnical changes reserved - 9 -4 Installation of FMG90BBefore installing, check that❒ the wetted materials of the device are suitable for the media being used( § 9 “Technical data”).❒ the equipment is switched off and is in a safe and de-energized state. ❒ the equipment is depressurized and has cooled down.SUITABLE TOOLS:Use only suitable tools of the correct size.4.1 Installation instructionsCAUTION! Risk of malfunction due to external magnetic fields! Magnetic fields close to the device can cause malfunctions and should be avoided.Ensure that no external magnetic fields are present at theinstallation site of the FMG90B.•The FMG90B can always be installed anywhere along the pipeline. However, straight sections of piping are preferable.Bubble-formation / run empty possibleDirt deposits possibleRun empty possibleDirt deposits possibleInstallation of FMG90BFMG90B Series• Installation can occur in horizontal and vertical pipes. The flow sensor is only suitable for application in completely filled pipe systems.•As a matter of principle magnetic inductive flow sensors are widely independent from the flow profile. An inlet section is not absolutely necessary.To reach a most highly accuracy of the measurement, you should use straight inlet and outlet sections according to the inner diameter. The inlet section has to be at least10 x inner diameter; the outlet section 5 x inner diameter in order to achieve the specified accuracy.•The inlet and outlet sections and the gaskets must have the same or a slightly larger inside diameter than the measuring tube in order to achieve the specified accuracy.•If two or more FMG90B devices are used side by side, maintain a separation of at least 1.0 in between adjacent devices.If adjacent devices are too close together, operation of both devices may be impaired due to mutual interference.4.2 AssemblyThe FMG90B is installed directly into the pipeline. The compact design and light weight of the unit make wall-mounting unnecessary.IMPORTANT NOTICES:• Only use suitable gaskets for installation.• Observe the flow direction indicated on the type plate. • Observe the mounting dimensions (♑ § 9.3 “Dimensions”).Select an appropriate location for installation(♑ § 4.1 "Installation instructions").To ensure the best possible measuring accuracy, a vertical installation position with increasing flow is preferable (no collecting of dirt deposits).Wrap the FMG90B connections with 1 to 2 wraps of threadtape (e.g. Teflon ® tape). Wrap tape in a clockwise direction, viewed form the end, leaving the first two threads uncovered. Make sure the tape does not intrude into the flow path.Attach the FMG90B with arrow pointed in the direction of flow. The fittings should be screwed into FMG90B hand tight.CAUTION! Material damage! Maximum torque 3.7 ft lb.While tightening, counter the FMG90B only by hand!If you use an open-end or a pipe wrench, the FMG90B can be damaged.To tighten the FMG90B, use an open-end or a pipe wrenchfor the fittings and only the hand for the FMG90B.FMG90B Series Electrical connection 5 Electrical connectionThe electrical connection of the FMG90B is made via the 4-pin plug M12x1 at the top of the housing.The wiring of the FMG90B depends on the ordered version. A distinction is made between frequency output or analog output and frequency output.CAUTION! Electric current!The electrical connection should only be carried out by a fully qualified electrician.De-energize the electrical system before connecting the FMG90B.Connection cable:Suitable connection cables with molded coupling socket M12x1 are available in different lengths as OMEGA accessories. The maximum permissible cable length is 10 m. Connection 4-pin plug M12x1:Screw the coupling socket of the connection cable to the plug of the FMG90B.Tighten the knurled nut of the coupling socket with a maximum torque of 1 Nm.Electrical connection FMG90B Series5.1 WiringsPinout:The pinout differs according to the chosen configuration of the device.

1000系列电磁流量计 1000系列电磁流量计 2.1工作原理
法拉第感应定律（指的是当导体通过磁场时会在导体内部产生感应电势）即 为电磁流量计测量的基础原理。这种测量原理可应用于具有导电性的流体，该 流体流入磁场垂直于流体方向的管道，在流体中感应生成的电势可利用对称布 置的两个电极进行测量。信号电压UE与磁感应强度B，电极间距D以及流体平均 速度v成正比。由于磁感应强度B与电极间距D为常量，所以信号电压UE与平均 流速v成正比。用于计算体积流速的等式表明信号电压UE与体积流量成线性正 比。
