SAFETY INFORMATION
INTRODUCTION
These operating instructions and description of device functions are provided as part of the scope
of supply.
They could be modied without prior notice. The improper use, possible tampering of the instrument
or parts of it and substitutions of any components not original, renders the warranty automatically void.
The ow meter realizes a measure with liquids of conductivity greater than 5µS/cm in closed
conduits.
Any use other than described in this manual aects the protection provided by the manufacturer
and compromises the safety of people and the entire measuring system and is, therefore, not
permitted. The manufacturer is not liable for damaged caused by improper or non-designated use.
Transport the measuring device to the measuring point in the original packaging. Do not remove
covers or caps until immediately before installation. In case of cartons packaging it is possible to
place one above the other but no more than three cartons. In case of wooden packaging do not
place one above the other.
Disposal of this product or parts of it must be carried out according to the local public or private
waste collection service regulations.
The converter must only be installed, connected and maintained by qualied and authorized
specialists (e.g. electrical technicians) in full compliance with the instructions in this Operating
Instruction, the applicable norms, legal regulations and certicates (depending on the application).

The specialists must have read and understood these Operating Instructions and must follow the
instructions it contains. The Operating Instructions provide detailed information about the device. If you
are unclear on anything in these Operating Instructions, you must call the ISOIL service department.
The converter should only be installed after have veried technical data provided in these operating
instructions and on the data plate.
Specialists must take care during installation and use personal protective equipment as provided
by any related security plan or risk assessment.
Never mount or wire the converter while it is connected to the power supply and avoid any liquid contact
with the instrument’s internal components. To connect remove the terminals from the terminal block.
Before connecting the power supply check the functionality of the safety equipment.
Repairs may only be performed if a genuine spare parts kit is available and this repair work is
expressly permitted.
For the cleaning of the device use only a damp cloth, and for the maintenance/repairs contact the
service center (for details see the last page).
Before starting up the equipment please verify the following:
Power supply voltage must correspond to that specied on the data plate
Electric connections must be completed as described
Ground (earth) connections must be completed as specied
Verify periodically (every 3-4 months):
The power supply cables integrity, wiring and other connected electrical parts
The converter housing integrity
The suitable tightness of the sealing elements
The mechanical xing of the converter to the pipe or wall stand

Before install the sensor locate the direction of the liquid in the piping
The sign of the ow rate is positive, when the ow direction it’s from – to + as printed on the tag plate.
If after the installation, for plant request becomes necessary reverse the sign of the ow, it's enough
reverse the sign of the coecient KA.

Install the sensor away from bends and hydraulic accessories
In vertical installations an ascending flow is preferable. For vertical installations with descending flow direction contact
the manufacturer
Avoid a partially empty pipe, during operation the pipe must be either completely full of liquid or completely empty

Tightening the 2 x M10 screw bolts without xing the chain could cause the sensor’s violent
ejection from the pipe.
WARNING FOR YOUR SAFETY: do not remove or modify the lock chain
To determine Z value, the formula considers the jacket sensor screwed up to 3/4 of the total
thread lenght

POSITIONS: 0(1/8D) - 1(1/2D) - 2(7/8D) the coecients Kp and Ki are calculated
automatically by the converter.
POSITION: 3Kp and Ki = 1 (default); relevant values of these coecients must be calculated

WARNING! The insertion and extraction operations of the insertion instruments are operations that
can be dangerous when working with the pressure tube.
The pressure inside the tube apply a signicant force on the probe that can be ejected violently,
creating dangerous situations for the operators. However, the protection chain provided by the
instrument does not allow it to completely escape from the cylinder linear.
It is recommended to perform the insertion or extraction operations of the insertion instrument in safe
conditions, if possible with not in pressure pipe or at least reduced pressure pipe.
The extraction operations can be dangerous as well as for the risk connected to the ejection forces
of the probe, also due to the possible leakage of liquid from the piping caused by incorrect operation
or defect in the shut-o valve. The following are the indicative values of expulsion force at dierent

For correct operation of the meter is NECESSARY that the sensor and the liquid are
equipotential, so ALWAYS connect the sensor and converter to ground. For grounding
with cathode protection pipe contact the manufacturer.
