SPECIFICATIONS
Description
Featuring 5 digits of rate and 8 digits of total, the BAT
R/T Millennium edition (BATRT-M) is a battery or loop
powered indicator capable of accepting magnetic pickup,
DC pulse and switch closure inputs from pulse produc-
ing flowmeters. The unit can be ordered with an optional
4-20mA output. The BATRT-M uses the 4-20mA loop to
provide power when this output is used.

Decimal Point Locations: XXXX.XXXX to XXXXXXXX
20 Point Linearization Option (10 Point with Data Logger option)
This feature allows the user to enter 20 different frequencies
with 20 different corresponding K-Factors to linearize non lin-
ear signals.
ANALOG OUTPUT OPTION:
Type: 4-20 mA follows rate display, Two wire hookup
Accuracy: 0.025% Full Scale at 20° C

NOTE:
The BATRT-M uses the 4-20 mA loop power as its pri-
mary power source when this option is used. The battery
is still required for standby battery operation.
