SECTION 1.0: INTRODUCTION

1.1 PURPOSE OF THIS GUIDE

The purpose of this guide is to provide installation and commissioning procedures and basic

operating and servicing instructions for the ONICON F-4000 Series Ultrasonic Flow Meter.

1.2 PRINCIPLE OF OPERATION

ONICON F-4000 Series Ultrasonic Flow Meters utilize the differential transit time method to

measure the velocity of relatively clean liquids in full pipes. By measuring the difference between

transit times of ultrasonic sound waves travelling between two transducers, the ow velocity and

direction are accurately determined.

1.3 TYPICAL F-4000 FLOW METER

The F-4000 Series Ultrasonic Flow Meter utilizes clamp-on signal transducers that mount on

the outside wall of the pipe. It is suitable for measuring the volumetric ow of liquids in a wide

variety of applications including bi-directional ow applications. The meter is housed in a steel

wall-mounted enclosure with a built-in user interface/display.
