• The EASZ-1 must be installed on an isolated 4-20 mA current loop. • If your wiring is grounded or shared with any other device, your EASZ-1 WILL NOT WORK. • The recommended wiring for the EASZ-1 begins on page 14 of this manual.
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.

Measuring Worldwide 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.
(1-inch EASZ-1) The EASZ-1 is not limited to measuring only water in oil. It is a device that can measure the concentration of one type of liquid in another. However, there must be a very big difference in the dielectric constant of the liquids in order for a meaningful measurement.
High Range EASZ-1’s are manufactured as a “rod within a pipe”, and can be recognized by looking inside the sensor. If the inner sensor is a solid rod, you’re looking at a High Range EASZ-1 which is capable of measuring all water content in higher ranges.
Refer to “as built” drawings on each order. HANDLING The EASZ-1 is supplied as a complete working instrument and its main parts should never be dismantled for any reason. In order to protect the instrument from damage, the operators who are installing the monitor should avoid doing the following: •...
Measuring Worldwide WIRING The EESIFLO EASZ-1 Water in Oil Monitor is a loop powered device. It runs on the power in the 4- 20mA current loop. For hazardous area applications, it is important to make sure whatever device is powering the loop is appropriate for the hazardous area in question.
INTRINSIC SAFE ISOLATOR–CONNECTION (Pepperl+Fuchs) We supply the P&F model KFDO-SCS-EX1.55 for these applications. If you wish to use other brands or model numbers, you will need to check with EESIFLO on their suitability. INTRINSIC SAFE LOCAL DISPLAY AND OUTPUT (Beka & Associates) A Beka display is often supplied as a local indicator for hazardous areas using the same loop power.
Always protect the EASZ-1 from electrical damage or erroneous readings by making sure you understand good electrical practices. If you are using the EASZ-1 in a non-hazardous application, the power/signal loop should be galvanically isolated unless the EASZ-1 and remote device are sharing the same local ground.
Measuring Worldwide STATIC ELECTRICITY Warning: Static electricity can damage the PCB. If you are configuring the EASZ-1 in a lab or company workspace, always make sure that there is no chance of static being transferred to the board. Static electricity will damage the board.
MOUNTING The EASZ-1 can be mounted in either a horizontal or vertical position. It is important to ensure that the pipe is always full of liquid. It is not advisable to mount it in a vertical position where the direction of flow is from up to down.
To improve the level of accuracy, it may be necessary to ensure that effective mixing occurs just prior to entering the EASZ-1. To maximize the accuracy of the EASZ-1, an inline static mixer will ensure the water and oil are mixed into a homogeneous solution prior to passing through the EASZ-1.
EASZ-1. The EASZ-1 assumes that it is always full of fluid. If it is partially filled with air or gas, the water content readings will be reduced because the Dielectric Constant of the Air/Gas is much closer to oil than water.
The sampling point can either be a standard “Tee” piece (threaded or flanged) added to the pipe work by the customer between the mixer (if installed) and the unit, or The sampling point can be ordered from EESIFLO factory fitted as a part of the sensor pipe and mixer (if required) EESIFLO®...
To connect the unit correctly follow the instructions: Before powering up the unit, make sure that any remote device that the EASZ-1 is connected to is galvanically isolated (see grounding/ isolation section.) Failure to properly protect the EASZ-1 electronics can result in catastrophic board failure.
2. Make sure that there is no chance of static electricity transfer from personnel to the card. If the EASZ-1 is being tested in a lab or a workshop, ensure that steps have been taken to ground the electronics and prevent any discharge of static electricity to the electronics due to handling.

The “cal” command is simply putting the measurement at specified point on the graph below. It is a Zero offset function, and the graph is linear. In most cases the default table in the EASZ-1 will be sufficient for most lower range scenarios.
Note: If it becomes necessary to perform a temperature coefficient procedure because the liquid is experiencing large temperature swings, refer to the chapter on temperature coefficient procedure. EESIFLO® is a US registered trademark serial number 77071229 29 | Standard Range...
Calculating your Temperature Coefficient is best performed with a sample of the actual oil being used in your process. Fill the EASZ-1 with what you consider to be dry oil at ambient temperature then use the get button in the EASZ-1 Interface software to recover a single capacitance and temperature value.

Although the EASZ-1 will show a reading in a non-flow static condition where there are these readings will be incorrect because of water and oil separation. The only meaningful calibration that can be done in a static condition is on a dry oil at process temperature to determine zero water.
Measuring Worldwide COMMUNICATION THROUGH THE HART MODEM The EASZ-1 has a built-in HART Modem. This option enables the user to communicate with the EASZ-1 remotely using a PC. Some additional operations have been added to the software which include the ability to trim the 4-20mA signal. This is useful in situations where the readings sent to...

This is similar to the “cal” command using RS-232. To calibrate the EASZ-1 use an uncontaminated sample of the oil that is being measured. (Uncontaminated oil contains no water) If you are sure that the oil is uncontaminated, and water free, then capture the capacitance and temperature by using store.
In this case, refer to the chapter on temperature coefficient procedure. To perform this function, you will need to capture the Temperature Compensation capacitance at 2 different temperatures to calculate TC which is a temperature coefficient.
