1010BXFM-3 Section 1
Dual Path
Dual Path uses two measurement channels to achieve a single output via a “virtual” third
channel. The resultant data is the average of the two channels. This meter type only supports
clamp-on or in-line transit-time operation.
Since System 1010BX is a multitasking, multifunction system, all necessary operations are
interleaved to guarantee the fastest operation and greatest real-time data density.
Installation Menu choices govern the functionality of the real-time operating system. For ex-
ample, data will be reported either in data units selected by the installer during the site setup
or default units, if the installer chose not to edit that menu choice. You can access the instal-
lation menu at any time to change the selected flow rate units. Note that changing primary
site setup data like the pipe outer diameter (OD) or the transducer model will invalidate the
site setup, thus requiring a reinstallation.
1.6 DESCRIPTION OF CHANNEL FUNCTIONS (1010DBX Systems only)
Dual channel 1010DBX systems provide two measurement channels that allow its operation
as two completely independent single-channel meters. In addition, you can combine the two
measurement channels in the various meter types described below to enhance the functional-
ity of the system. On single channel systems, you do not get a choice of meter types since this
requires two independent measurement channels.
