Integral 2x16 Character LCD panel display shows real-time data and Installation Menu for key-
pad input or RS-232 remote programming.
z
Flexible mounting: Integral and/or Remote - either on pipe or located up to 300 feet (100m) from
the transducers. For distances greater then 300 feet (up to 1000 ft), please contact Siemens
Customer Service.

Wide-Band pipe matching provides high performance and stability for Steel pipes.
z
ZeroMatic Path sets Zero flow compensation without stopping flow; eliminates zero drift.
Integral Datalogger
FUS1020 provides an integral Datalogger that records user-assigned data at a programmable log
interval for later retrieval. Data reports can be transmitted via the RS-232 port to either a serial printer
for hard copy, or to a PC/laptop computer where the report format is comma-delimited ASCII text to
facilitate its import to spreadsheet or database software.
Analog Outputs
z
Loop powered isolated current varies from 4-20 mA in proportion to any user-selected data
function.
z
Digital PGEN output pulse function allows user assigned PGEN digital signal pulses per unit of
volume.
z
Buffered open collector relay trigger output provides logic levels for response to user-assigned
alarm functions.
