The default display resolution is 0.001 Unit.
b) Accumulated flow can choose positive accumulation, negative
accumulation and net accumulation
，
The default display is net accumulation.
c) When the display value of minimum resolution reaches maximum, the
resolution of screen display will be carried automatically, and the maximum

Communication Output Modes
Ultrawater ultrasonic water meter has three output modes. The three output
modes are integrated into a communication module. The three output modes
are all passive output through connecting wires. It needs external 8-24V
AC/DC power supply. The output mode can be used simultaneously or
separately, and the output mode can be selected by setting Modbus.
a)
Pulse Output
（
See Section 3.6
）
b)
4-20mA Outpu
t
（
See Section 3.7
）
c)
Modbus Output
（
See Section3.8
）
When different output modes are selected, the corresponding icon
will always be illuminated.
When using pulse and current loop output for a long time, the endurance of internal battery
will be seriously consumed. MODBUS output is highly recommended. If it is necessary to use
pulse and current loop output, please connect 8-24v AC / DC externally, please inform when
ordering.
