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”.).

2.2. Operating Principle

The flow sensor consists of a transducer and a five-blade open cell paddlewheel using

insertion technology. The paddlewheel is equipped with a permanent magnet

integrated into each blade. As the magnet passes close to the transducer a pulse is

generated. When liquid flows into the pipe, the paddlewheel is set in rotation

producing a square wave output signal. The frequency is proportional to the flow

velocity. The sensor is installed into the pipe using a wide range of insertion type

fittings supplied by the flow sensor manufacturer.

4. Installation

4.1. Location

Different pipe configurations and obstacles in the flow line such as valves, elbows, pipe

bends and strainers create variations on the flow profile.

Whenever possible follow the EN ISO 5167-1 installation recommendations to locate

the sensor.

Always maximize distance between flow sensor and pump.

4.2. Mounting Position

Make sure the pipeline is always full.

Horizontal pipe runs:

Fig. 1: installation with no sediments present

Fig. 2: installation with no air bubbles present

Fig. 3: installation if sediments or air bubbles may be present

Vertical pipe runs:

Install sensor in any orientation. Upward flow is preferred to ensure full pipe.

4.3. Process Connection

1. Place the flat gasket, sensor, and the

screws with washers making sure that the

arrow is in line with the slot milling of the

weld on adapter

2. tighten the screws with a force equal to 15

4.4. Wiring

Always ensure the power supply is switched off before working on the sensor.

Always use a high quality (regulated) DC voltage supply.

2.7Kohm Pull-up resistor may be required.

N.B. The slot milling of the weld

on adapter must be parallel to

the flow. The arrow on the

sensor must be close to the

milling weld on adapter.
