Installation INSTALLATION THIS PRODUCT SHOULD BE INSTALLED AND SERVICED BY TECHNICALLY QUALIFIED PERSONNEL TRAINED IN MAINTAINING INDUSTRIAL CLASS FLOW INSTRUMENTATION AND PROCESSING EQUIPMENT. READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING THE UNIT. IF YOU HAVE ANY QUESTIONS REGARDING PRODUCT INSTALLATION OR MAINTENANCE, CALL YOUR LOCAL SUPPLIER FOR MORE INFORMATION.
Installation Installation Recommendations The transmitter is a simple device to install However, the following measures are recommended for reliable, trouble-free operation: • Align pipe accurately Piping should be accurately aligned and of correct length The high pressure body of the transmitter can withstand shock and flow/pressure pulsation However, the piping should be firmly supported by external mounting brackets, both upstream and downstream of the meter, to avoid any pipe flexing actions that could reduce meter life...
Installation Installing the Transmitter 1 Disconnect the electrical power from the target system before making or changing any transmitter connections 2 Use 005 A fast-acting fuse if non-current limited power sources are used 3 Terminate cable shield connection at either DC ground or earth ground 4 Mount the transmitter so fluid is traveling in the direction of the flow arrow Flow Direction Arrow Flow Inlet...
Electrical Connections ELECTRICAL CONNECTIONS The standard cable length provided with an MR Transmitter is 150 ft (457 m) and includes a soldered, Hirschmann cable connector, assembled from the factory Additional cable lengths, shorter or longer, are available to match application requirements To connect the cable assembly to the transmitter, press the cable connector into the connector receptacle on the transmitter The cable only inserts in one direction If the connector does not seem to fit, do not force it Rotate the cable connector 90 degrees and...
