1. Introduction

1.1. Safety Instructions

General Statements

The sensor F3.20.X.XX has only been designed to measure the flow of liquids.

Do not install and service the sensor without following the Instruction Manual.

This sensor is designed to be connected to other instruments which can be
hazardous if used improperly. Read and follow all associated instrument
manuals before using with this sensor.

Sensor installation and wiring connections should only be performed by qualified
staff.

Do not modify product construction.

Installation and Commissioning Statements

Remove power to the sensor before wiring any connection.

Depressurize and vent the system before installing or removing the sensor.

Check and confirm the chemical compatibility of the materials in contact with the
liquid.

Do not exceed maximum temperature/pressure data.

To clean the sensor, use only chemical compatible products.

1.2. Unpacking

Please verify that the product is complete and without any damage. The following
items must be included:

F3.20 Paddlewheel Flow Sensor

Instruction Manual for F3.20 Flow Sensor

2. Description

2.1. Design

The simple and reliable paddlewheel flow sensor type F3.20 is designed for use with
every kind of solid-free liquids and to be installed on high pressure plants. The sensor
can measure flow from 0.15 m/s (0.5 ft/s) producing a frequency output signal highly
repeatable. A rugged construction and a proven technology guarantee exceptional
performances with little or no maintenance required. A specially designed family of
fittings ensures an easy and quick installation into all pipe materials in sizes from DN40
to DN200 ( 1 ½” to 8”.).
