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,

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).

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 ca
