ULF Ultra Low Flow Sensor

1. Introduction

1.1. Safety Instructions

General Statements

The sensors ULF01.X.X and ULF03.X.X have only been designed to measure

the flow of liquids.

Do not install and service the sensors without following the Instruction Manual.

These sensors are 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:

ULF Ultra Low Flow Sensor

Instruction Manual for ULF Ultra Low Flow Sensor

Instruction Manual for K330U or K315U Output KIT (only for ULF3.30 or

ULF3.15 version)

ULF Ultra Low Flow Sensor

2. Description

2.1. Design

The compact ultra-low flow sensor type ULF is designed for use with every kind of

aggressive and solid-free liquids. The sensor can be fixed to flexible or rigid pipes via

¼” GAS threaded process connections. The paddlewheel sensor produces a frequency

output proportional to the flow velocity that can be easily transmitted and processed.

The ULF sensor offers two different flow ranges starting from 1.5 or 6 l/h (0.0066 or

0.0264 gpm). The construction materials, POM or ECTFE (Halar), provide high

strength and chemical resistance.

2.2. Technical Features

Halaris a registered trademark of Ausimont-Solvay.

2.3. Operating Principle

The flow sensor consists of a transducer and a five-blade paddlewheel. 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

sensor body, the paddlewheel is set in rotation producing a square wave output signal.

The frequency is proportional to the flow velocity.

2.5. Output Devices

2.5.1. K315U – Frequency Output & MIN alarm KIT

This Kit consists of an additional IP65

housing mounted aside the sensor via a

PVC plate. It is equipped with an open

collector frequency output and a

mechanical SPDT contact. The MIN alarm

set-point can be freely set by a

potentiometer up to 21 l/h (0.09 gpm) for

ULF01 and 53 l/h (0.23 gpm) for ULF03.

When the flow velocity drops below the

adjusted limit the relay output opens and

the Local Status Indicator changes colour.

It has been designed to protect a pump

from running dry or pumping against a

closed valve in the main pipeline.

2.5.2. K330U – 4…20 mA Output KIT

This Kit consists of an additional IP65

housing mounted aside the sensor via a

PVC plate. It is a blind transmitter

designed to convert the signal from the

sensor into a 4…20 mA output for long

distance transmission.

2.5.3. Installation

The K315U and K330U Kits can be ordered directly mounted on top of the flow sensor

or separately and then simply installed on the proper sensor.

Please refer to the Instruction Manual of the Output KIT for proper installation and

calibration.

4. Installation

4.1. Location

The sensor can be installed in any position, both horizontally or vertically, although

horizontal flow is preferred. A non horizontal installation may cause a greater error in

the lower part of the measurement range.

Install the sensor with the arrow pointing the direction of the flow.

Always maximize distance between sensor and pump. Do not install the sensor

immediately downstream of valves, elbows or any kind of obstacles: 150 mm of

straight pipe are suggested before and after the sensor.

4.2. Wiring

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

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