User manual for - FLOW METER SPP-N118
- Do not use the unit in areas with significant temperature variations, exposure to
condensation or ice.
- Do not use the unit in areas exposed to direct sunlight.
- Make sure that the ambient temperature (e.g. inside the control box) does not
exceed the recommended values. In such cases forced cooling of the unit must
be considered (e.g. by using a ventilator).
The unit is designed for operation in an industrial environment and must
not be used in a household environment or similar.

GENERAL CHARACTERISTICS
is measurement of instantaneous flow (flow rate), and counting of
total flow (e.g. passage of fluid or gas ), The device can be used as regulator, to control
industrial process. Measurement of instantaneous flow can be indicated in range: 0 to 9999
(plus decimal point) and can be expressed in combination of two cubic measures (Litre and
m
3
) and three time measures (second, minute, hour). Total flow can be indicated in range
from 0.000 to 4294967295 m

with maximum resolution of 0.001 L.
can cooperate with flow sensors with current output (0-20mA or 4-20mA).
Sensors can be powered from sensor supply output (stabilized, 24VDC +5%, -10% 100mA).
The device can be equipped with two relay (or OC type) outputs, which can be driven due
to instantaneous flow, total flow or batcher counter value. Optionally
with two relays
outputs can be equipped with active current output. Build in RS 485 interface enables access
to all internal registers, and supports MODBUS RTU communication protocol. The controller
can be ordered in two power supply versions. The meter can be ordered in three power supply
versions.
The device has 5 buttons being used for main presets programming. To get high
protection level, the keyboard is mounted under transparent cover. To allow user to change
presets without opening the cover, an IR sensor is mounted. Remote controller keyboard is
equivalent to the device keyboard (Note, that remote controller is not a part of the
set – it is an additional equipment).
Additional features:
•
alarm preset; alarm signal is released when measurement exceeds measurement range
•
direct access to relays thresholds settings, without password,
•
batcher mode.
