Pulsar Quick Start Manual - Ultra 5
Congratulations on your purchase
of a Pulsar Ultra 5!
This quality system has been developed
with the latest digital ultrasonic tech-
nology for liquids, slurries, and solids.
No more noise and beam angle issues.
It provides non-contacting level, vol-
ume, advanced pump control, differen-
tial level, and open channel flow with 5
user-defined relays. Comes standard
with 110VAC and 24VDC with an iso-
lated 4-20 mA output.
LIQUIDS and SOLIDS
• Mount the transducer away from any obstructions, fal-
ling water/solids, rough walls, pumps, switches, etc…
• Visualize looking down the echo path of the transducer
and seeing a nice clear shot (2’+ dia.) to the very bot-
tom during fill and empty cycles.
• Ensure the maximum level does not come within the
minimum dB blanking distance.
• Confirm the inside of the standpipe is smooth and does
not have any protrusions at the weld.
• Do not hang the transducer by the cable.
• Typically, mount the dB transducer 1/2 the tank radius.
(Call Pulsar Technical Support for Special Service
Passcode and Instructions 850-609-1777.)
LIQUIDS
• Dome top tanks will require Gain & Algorithm change.
• If reading false level, use P21 and set true distance
SOLIDS
• Consult factory if the silo is extremely dusty—we can
increase the return signal strength (even during fill).
• DATEM may map-out the true echo. Use P21 to set
true distance and turn “Update Datem” off!
• If acoustically noisy, change Algorithm to Largest.
TRANSDUCER WIRING
TERMINAL IF SPLICING (shielded pair)
RED = POWER RED = BLACK
WHITE = SIGNAL WHITE = WHITE
BLACK & GREEN = 0V BLACK & GREEN = SHIELD
• Use any standard, 2 conductor/shielded pair for splic-
ing (recommend 18 AWG gauge, UV protected)
• Use 16 AWG gauge if going 500 - 3,000 ft cable run.
• Transducer shield is required - do not cut or float!
• Battery is actually the 24VDC terminals.
• If I.S. Zone 0 is required, consult factory for details.
