Multi-Functional Level Control

System

General

Scope

This section describes the requirements for a multi-functional level controller

system. Under this item, the contractor shall furnish and install the multi-

functional level controller system, and all associated equipment and accessories

as indicated on the plans and as herein specified.

Submittals

The following information shall be included in the submittal for this section:

 Data sheets and catalog literature for system components.

 Interconnection and dimensional drawings.

Basic System Description

The multi-functional level control system (level system) shall employ acoustic

echo-ranging technology to determine the distance between the transducer and

monitored surface, as a basis for display, output, and digital communication.

The level system shall consist of a microprocessor based level controller and an

ultrasonic transducer (transducer) for single point operation.

The level controller shall be operator configurable to meet specific application

requirements by implementation of available signal processing and process

control functions, in any allowable combination.

Level Controller Functions

Signal Processing

The level controller shall:

 Employ an ultrasonic transceiver suitable for providing excitation to, and

processing resultant signals from the attached ultrasonic transducer.

 Create a digitized echo profile, and apply patented Sonic Intelligence

echo processing techniques to select and verify the echo representing

the reflective surface monitored.

 Shall employ Auto False Echo Suppression with the ability to

automatically reject signals created by obstructions in the sound wave

beam path and determine true material level.

 Calculate the distance between the transducer face and reflective

surface based on the echo selected. The calculated distance may be

converted to represent: material level, differential level*, average level*,

space, material volume, vessel ullage, pumped volume, or head, open

channel flow rate, and/or total flow volume. (* Additional transducer

required.)

 Compensate temperature-induced variation in the acoustic wave

propagation velocity in air. This compensation shall be based on the
