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

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.
