Intr

oduction

By utilizing ultrasonic echo ranging principles with Sonic Intelligence and velocity
compensation, the SPL provides outstanding measurement accuracy, usually within
0.25% of range.

The distance calculation may be converted to space, material level, material volume,
or remaining vessel capacity. The Reading chosen (and operating data) is displayed
on the

Liquid Crystal Display

(LCD).

The relays and mA output 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 SPL 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.

With the addition of a Milltronics Smartlinx

®

protocol specific ‘plug-in’ communications

module, the SPL is compatible with popular industrial control system standards.

Programming can be done locally using the portable programmer keypad, or
remotely through optional Dolphin Plus software or SmartLinx
