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
Nm

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.
