SLS-1500 Datasheet, PDF (3/5 Pages) List of Unclassifed Manufacturers – Compact Flow Meter for Industrial Applications

3.6 Digital Communication via I²C-Bus
The SLS-1500 liquid flow meter has been designed
for use with the SCC1 interface cables. For special
applications, direct communication with the flow meter
via the standard I²C-interface is possible. The
physical interface consists of two bus lines, a data
line (SDA) and a clock line (SCL) which need to be
connected via pull-up resistors to the bus voltage of
the system.
These lines may be used on 3.3 V or 5.0 V levels with
a recommended clock frequency of 100 kHz. For the
detailed specifications of this I²C communication,
please refer to specific I²C Application Notes from
Sensirion.
