The distance calculation may be converted to space, material level, material volume, remaining vessel
capacity, differential level, or average level Readings. The Reading chosen (and operating data) for each
vessel is displayed on the
Liquid Crystal Display
(LCD).
The relays and mA outputs may be used as preset (or programmed as desired) to activate alarms and/or
operate remote monitoring equipment and/or process control equipment.
As well, the DPL+ may be connected to a Milltronics
BIC-II
(Buffered Interface Converter) to provide
RS-232C and/or RS-422 communications for host computers, Distributed Control Systems, and
special
(capable of operating as a host device) Programmable Logic Controllers.
Operator programming is accomplished using a Milltronics infrared programmer and is stored in non-volatile
memory, unaffected by power interruption. The infrared interface permits one programmer to be used for any
number of DPL+ level monitors. Upon programming completion, the removable programmer may be locked
away, thereby securing all programming.
While the DPL+ is typically used to monitor material level in open or closed vessels, any process which
requires a distance measurement (within the system range) is a candidate for DPL+ application.
Refer to Application Examples for detailed descriptio ns of a small sample of
process measurement requirements to which the DPL+ may be applied. If process or equipment position
monitoring at distances greater than 60 m (200 ft) is required, refer to Example - 6, Tripper Measurement.
Throughout this manual (unless stated otherwise) references to material level also apply to any material or
object surface to be monitored by the DPL+.
