  • Page 14 RPmag - installation INSTALLATION GENERAL CRITERIA The fl owmeter can test automatically fl ow direction. Because the direction arrow marked on the nameplate is fl ow direction when calibrated in factory, you should install the fl owmeter to make the actual fl ow direction same as the fl ow direction arrow marked on the nameplate.
  • Page 15 RPmag - installation The electromagnetic fl owmeter must be installed so that the pipe is always completely fi lled with fl uid. In partially fi lled pipe case, the fl owmeter must be installed with the siphon phenomenon, for which the pipe stretch where the meter is installed is kept always full.
  • Page 16 RPmag - installation The electromagnetic fl owmeter can not be installed at the pipe highest point, because air or gas accumulations may occur in the measuring pipe. See Fig.15-A Fig.15-A Installation at highest point The electromagnetic fl owmeter can not be installed upstream of a pump to prevent cavitation, which can damage the sensor lining.

It should be prevent from the leakage of the corrosive liquid.
  • Page 18 RPmag - installation MOUNTING REQUIREMENTS a) The sensor pipe and the line pipes must have the same axis. For the sensors under DN50, the axial diff erence between the measuring tube and operating pipe should be less than 1.5mm; for the sensors from DN65 to DN300, it should be less than 2mm;...
  • Page 19 RPmag - installation 7.10 EQUIPOTENTIALITY AND ELECTRICAL INTERFERENCE REDUCTION The measuring circuit assumes the fl uid at ground potential, as it is in most of application with conductive pipes. The sensor is isolated from the fl uid because of the lining, therefore it’s necessary to connect the grounding cables to the pipe’s fl...
  • Page 20 RPmag - installation c) Some systems, such as pipes with cathodic protection, may be aff ected by potential disturbance because not all the line is at ground potential. In order to eliminate this type of interference, it must be isolate the line with two rubber pipes as shown in Fig.19A.
