6.1. Intended use and features The electromagnetic flowmeter PEM-500 is designed for volumetric measurement of the flow rate of conductive liquids in piping systems. It measures the flow and volume of the fluid flowing in both directions. Complete filling of the sensor tube by the fluid is required for correct measurement. -
Page 9: Table 1. Pn 16 Sensor Data
EN.IO.PEM.500 The sensor enclosure is made of non-magnetic material, welded with flanges and a set of fastenings. An insulating insert of the required properties is placed inside the tube (compatible with the type of fluid). The system of electromagnet coils generating the required magnetic field is fixed directly on the measuring tube. -

Page 11: Installation
EN.IO.PEM.500 INSTALLATION 7.1. General recommendations − It is recommended that the flow direction matches the direction of the arrow on the sensor; the transmitter is set by default to operate in that direction. It is possible to reverse the flow direction on the instrument in operation, but then the flow direction must also be changed in transmitter parameters. - Page 12 EN.IO.PEM.500 In order to avoid metrological errors caused by air bubbles or lining damage, the following points must be observed: during installation, the sensor must be properly positioned, the flange bolts must be tightened simultaneously on both sides; it is recommended that the flowmeter be installed so that the axis of the electrodes is ➔...

Page 14: Electrical Connection
EN.IO.PEM.500 ELECTRICAL CONNECTION All connection and installation operations must be performed with supply voltage and other external voltages (if used) disconnected. A circuit breaker must be installed next the flowmeter transmitter (in the same room) on the flowmeter feeding line. It must be easily accessible and clearly and unambiguously marked with symbols compliant with local electrical equipment safety regulations. -
