✓You must carefully read all the instructions in this manual. You must not start the installation

before taking these instructions into account.

✓This equipment might receive some hazardous voltages. If you do not consider taking these

instructions seriously, you may risk facing serious injuries.

✓Before setting up your installation, check the model suits your application. The wiring of this

equipment must comply with regulations and be executed by qualified personnel.

Start up Instructions (Hazardous Area Versions)

•FUNCTION: The EASZ-1 Water In Oil Monitor (Water-Cut / BS&W) is aimed at measuring water

content in hydrocarbon liquids. The equipment delivers a 4-20 mA signal proportional to the

measured water content.

•ATEX MARKING MEANING AND ATEX INSTALLATION ZONES: refer to the following page

•INSTALLATION

✓Location: This equipment can be installed in defined explosive atmospheres and is in

compliance with the 94/9/EC ATEX directive. The surface temperature must not exceed that

indicated by the label.

✓Fixing and mounting: The housing must be protected against mechanical shocks. No drilling or

machining must be done. Make sure the cable gland is appropriately tightened and make a

loop with your cable to avoid running water alongside. If you do not take these precautions

into account, the envelope certification will be at risk and the ingress of protection of the

housing might be invalidated.

✓Electrical wiring:Electrical wiring must be executed when DE-ENERGIZED after mounting and

fixing the instrument. Electrical wiring must be executed with respect to sound engineering

practices and enforced norms. Cables must be of the shielded type. In order to guarantee a

perfect tightness, the cable gland should be screwed with an appropriate spanner. Terminal

wiring is designed for 1.5mm² wires.

✓Cable paths: The type and the path of cables (I.S. cables) must comply with regulations. Careful

precautions must be taken to avoid electromagnetic coupling with other cables capable of

causing hazardous voltages or currents. Cables and wires must be protected against any

damage.

✓Specials conditions for a safe use: refer to the following pages.

✓SETTING: Setup can be done using the serial link cable or using a HART interface. Setup using

the serial cable is only to be done in safe zone. HART can be used in hazardous areas provided

a HART terminal with appropriate certification is used.

Maintenance (Hazardous Area Versions)

•Precautions to be observed during maintenance.

✓The dismantling of the equipment must be executed when DE-ENERGIZED.

✓EESIFLO guarantees the certification of the equipment Ex-Works. Any operation other than

software changes will rule out EESIFLO’s responsibility in case of failure. If a fault is suspected

or observed, the equipment must be checked / repaired only by authorized personnel or

Introduction to EASZ-1

The EASZ-1 is an Online Water in Oil Monitor which has been designed to fit in a piping system and to

measure the water content in an oil when there is a positive flow. The measurement works correctly

only with a positive flow, unlike a laboratory instrument that will measure the water content of oil in

a static condition. All wet calibrations of the instrument must be conducted while liquid is flowing

through the unit and the liquid must be well-mixed.

Flow loop showing positive flow.

There are several reasons why the EASZ-1 requires a minimum flow to operate. Although it is capable

of giving a reading in a static condition (no flow) it is important to understand that oil and water

separate very quickly, and this separation may cause errors in the measurement. Water and oil do not

easily mix but they begin to mix in a flowing stream, especially when they have to go through or around

obstacles or if energy is applied. It is the responsibility of the user to ensure that the water and oil are

well mixed in the pipe to obtain best results.

Basic Principle of Measurement

The EASZ-1 measurement units are in in picofarads (pF) A picofarad is a unit used to measure

capacitance i.e., the ability of a system to store an electric charge.

Measurement of Capacitance between 2 plates

Instead of measuring the capacitance between 2 plates, the EASZ-1 is measuring the capacitance

between 2 pipes. The mechanical measurement section consists of 2 pipes, an inner and outer pipe.

The EASZ-1 measures the ability of the liquid to store energy while passing through these 2 pipes.
