Installing an EMUX
Establishing remote, wireless communications with an externally-
powered FlowHawk monitor that also will be connected serially to a
SCADA or other process control system through an RTU (Remote
Terminal Unit) requires installation of an EMUX (p/n 106226E).
Locate the EMUX outside the manhole (in which the monitor is
installed) in the proximity of the RTU and/or external power source
within a weatherproof (for outdoor installation) or other protective
(for indoor installation) enclosure. Installing the EMUX primarily
involves the following procedures:
 Installing the communication cable
 Installing the wireless EMUX
 Connecting the communication cable to the monitor
 Installing a wireless antenna
 Connecting an RTU to the EMUX
 Providing external power to the unit
Installing the Communication Cable
Unless the monitor will be located outside a manhole, the
instructions for installing the communication cable for the EMUX
are the same as for the standard EMU. Therefore, please refer to
Installing the Communication Cable on page 4-20 for instructions.
If the monitor will be installed outside a manhole, proceed directly
to the following section, Installing the EMUX.
