Functional Description
FlowCERT LITE 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 FlowCERT LITE. The time taken to receive the echo is
measured and the distance from the transducer face to the surface being
monitored is calculated.
FlowCERT LITE can measure from zero to 49.213 feet (15m) 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, level space, distance, OCM
head, or OCM flow, independently from that shown on the display.
Additionally there is an RS232 port, so that the FlowCERT LITE can be
operated remotely by a PC or other equipment.
FlowCERT LITE 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 FlowCERT LITE memory, in case an alternative set of
parameters needs to be stored.
Five 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 ‘all new’ dB transducer range, the FlowCERT LITE lives up to
its reputation as the most reliable ultrasonic level measurement system
available.
The Pulsar FlowCERT LITE ultrasonic level controller has been designed to
provide maintenance-free fit and forget performance.
