User manual - FLOW METER SPI-73
- In order to minimize fire or electric shock hazard, the unit must be protected
against atmospheric precipitation and excessive humidity.
- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,
humidity, corrosive gasses and oils.
- Do not use the unit in areas where there is risk of explosions.
- 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.
easurement of instantaneous flow can be indicated in range: 0 to 999999 (plus decimal
point) and can be expressed in any scalable user units of flow and three time measures
(second, minute, hour). Total flow can be indicated in range from 0.000 to 4294967295 user
units with maximum resolution of 0.001 units. Device can operate with different flow sensors,
acceptable flow factors of sensors from 0.01 to 10000.00 pulses per unit (with resolution 0.01
pulses/unit), additionally these flow sensors can be equipped with either electronic (open
collector) or contact output.
Sensors can be powered from sensor supply output (stabilized, 24VDC +5%,
-10% 100mA). The device is equipped with one relay (or OC type) output, which can be driven
due to instantaneous or total flow. 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.
Modern design guarantees high operational reliability. Front panel is protected from dust
and water spatters.
Additional features:
•
settable width of measurement window ( from 0.1 to 39.9 seconds),
•
direct access to relays thresholds settings, without password,
•
alarm pre-set; alarm signal is released when measurement exceeds measurement range,
can operate with flow sensors like
M1RSP
, equipped with
contactron output.
