Functional Description
Ultra 3 sends a transmit pulse to the transducer, which emits an ultrasonic
pulse perpendicular to the transducer face, and the returned echo is sent back
to the Ultra 3. The time taken to receive the echo is measured and the
distance from the transducer face to the surface being monitored is
calculated.
Ultra 3 can measure from zero to 131 feet (40m) from the face of the
transducer to the surface being monitored, dependent on the application
chosen and transducer used.
The relays can be programmed to activate alarms, pump starters, or other
control equipment. There is an isolated 4-20 mA output that can be
connected to a recorder or PLC, to monitor, depending on application
chosen, level, space, distance, OCM head, OCM flow or volume,
independently from that shown on the display. There is an RS232 port, so
that the Ultra 3 can be operated remotely by a PC or other equipment.
Ultra 3 can be programmed either by the built-in keypad (standard on all
wall and fascia units), or by PC via the RS 232 Serial Interface (optional).
All parameters are stored in non-volatile memory, so are retained in the
event of power interruption. A second backup copy of all parameters can
also be retained in the Ultra 3 memory, in case an alternative set of
parameters needs to be stored.
Three user definable control relays with individual setpoints and intelligent
performance logging software features ensure maximum control versatility.
The system utilises the unique DATEM software (Digital Adaptive
Tracking of Echo Movement). This is a proven digital mapping technique
developed especially for the Pulsar Ultra range, which gives the system
unequalled ability when identifying the “true target level” in the face of
competing echoes from pipes, pumps or other obstructions. Coupled with
the powerful, long-range abilities of the ‘all new’ dB transducer range, the
Ultra 3 lives up to its reputation as the most reliable ultrasonic level
measurement system available.
The Pulsar Ultra 3 ultrasonic level controller has been designed to provide
maintenance-free fit and forget performance.
