1. INTRODUCTION
1.1 PREFACE
The wall-mount product family is designed to be installed in a fixed location for long-term flow
measurement.
The flow meter is based on transit-time flow measurement principle. It measures the flow rate of liquid in a
closed pipe by using a pair of clamp-on or wetted ultrasonic transducers. In general, the liquid should be full in
the pipe, and should contain no or small amount of particles or air bubbles. Examples of applicable liquids are:
water (hot water, chilled water, city water, sea water, etc.); sewage; oil (crude oil, lubricating oil, diesel oil, fuel
oil, etc.); chemicals (alcohol, acids, etc.); waste water; beverage, liquid food, solvents and other liquids.
The utilizes state-of-the-art technologies such as advanced signal processing, low-voltage transmitting,
small signal receiving, self-adaptation, the latest electronics, etc., to achieve high accuracy and reliable
performance. Besides, the EUROSONIC 2000 product provides versatile output interfaces, both analogue and
digital, which can be easily used by a host computer or a flow controller.
