The Pulsar Oracle 160 open channel flow meter provides
non-contacting, maintenance-free accurate flow measurement and
control, in a wide range of flumes and weirs by calculating flow
from the measured head preceding a primary measurement device (PMD),
using the time of flight, through air, ultrasound technique.
Flow calculation is to the British Standard BS3680 where
applicable.
The Oracle 160 uses advanced
measurement and control routines, which include on board
totalisation of flow and outputs for remote logging and alarm,
will provide real advantages in the application. The standard
choices of PMD factory installed give ease of calibration in
comparison to other open channel flow units available.
Available as a 3 or 5 relay unit
ensure maximum application choice and control versatility. Full
flexible Pen-stock control is standard
The high level specification,
which includes ac and DC supply capability in one unit, back lit
LCD display, pump control software routines, two-way digital
(RS232) communication and a choice of integral or optional
remote programming, is all available in a choice of wall mount,
fascia mount, panel mount or 19 inch rack mounting
configurations.
An optional analogue input on the
5 relay version only allows the unit to accept input from
Pulsars SPEEDY devices to provide, (for instance velocity) to
enable an "area times velocity" Q=VA calculation to be
utilised in situations where no PMD is present.
