There is an isolated 4-20 mA output for each point of measurement that can
be connected to a recorder or PLC, to monitor
level space, distance ,
volume , OCM head or flow (dependant on the application chosen),
independently from that shown on the display. There is an RS232 port, so
that the UltraTWIN
can be operated remotely by a PC or other equipment.
UltraTWIN can be programmed either by the built-in keypad (standard), 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 UltraTWIN
memory, in case an alternative set of
parameters needs to be stored.
The system utilises the unique DATEM software (
D igital A daptive T racking of
E cho M ovement). 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 UltraTWIN lives
up to its reputation as the most reliable ultrasonic level measurement
system available.
The Pulsar UltraTWIN ultrasonic level controller has been designed to
provide maintenance-free fit and forget performance.
The UltraTWIN can show
level , space, distance, on the display. The relays
can be programmed to activate alarms, pump starters, or other control
equipment. In addition, the digital inputs can be used to modify pump and
control regimes to optimise performance. There is an isolated 4-20 mA
output that can be connected to a chart recorder or PLC, to monitor level,
space or distance, independently from that shown on the display. There is an
RS232 port, so that the UltraTWIN can be operated remotely by a PC or
other equipment.
The UltraTWIN is programmed by the built-in keypad or by PC via the RS
232 Serial Interface (optional). All the 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 UltraTWIN, in case
a previous set of parameters needs to be restored.
