PULSAR MEASUREMENT

It gives the system
the edge when identifying the “true target level” in the
face of competing echoes from pipes, pumps or other obstructions. When
coupled with the powerful, long range abilities of a dB transducer and radar
range, the Zenith 140 level and pump controller has no equal.
The Zenith 140 can measure from 0.077m to 25m from the face of the
transducer to the surface being monitored, dependent on the transducer
used.
The Zenith 140 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 Zenith 140 can be operated remotely by a PC or
other equipment.
The Zenith 140 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 Zenith 140, in case
a previous set of parameters needs to be restored.
