Page 3: Introduction To Easz-2
Construction Flanged 1” to 48” The EESIFLO EASZ-2 Water-In-Oil Monitor is a full-bore inline and online highly accurate product designed to continuously monitor the water content in a flowing hydrocarbon media (oil). It is inline because it can be fitted easily into an existing pipeline and online because it can continuously monitor and transmit the values to a remote location. -

Page 7: How The Easz-2 Works
3. How the EA SZ-2 Works 3.1. Unit Description The EASZ-2 comprises 2 main parts: the Body and the Sensor Pipe. The Body has two main parts, the base and the cover which screws onto the base. Both parts are die- cast aluminium and powder-coated and the cover also has a safety glass viewing window. -
Page 8: Functionality
3.3. Functionality The EASZ-2 Water-In-Oil Monitor (Water-Cut / BS&W) is designed to continuously measure the water content in hydrocarbon fluids: ■ Accurately ■ Reliably ■ Provide a linear analog or digital output The fluid being measured flows through a fixed electrode assembly in the sensor pipe which measures the dielectric constant as a variable capacitance across the electrode. -

Page 19: Intrinsic Safety
4.9. Intrinsic Safety When using EASZ-2Ex, the unit must only be connected to intrinsically safe certified equipment. This association must be compatible to the intrinsic safety rules. The electrical parameters of this equipment must not exceed the values indicated in the “ATEX Specification” table. When using EASZ-2Ex the unit is intrinsically safe and an intrinsically safe isolator must be used before the power supply in the safe zone and any units in the hazardous area. -

7.3. Lab Calibration Service EESIFLO also offer a Laboratory Calibration Service whereby customers can send their exact oil and unit to an EESIFLO authorized Service Centre for exact Calibration. This type of calibration is most beneficial when users who simply want to have the instrument supplied for an application and have the highest “out of the box”... -
Page 25: Two-Point Calibration Procedure
If this calibration is performed correctly the accuracy of the readings is ± 0.1%. Should a higher accuracy of ± 0.05% be required it is necessary to use the factory calibration service from an EESIFLO authorized service centre. To calibrate the unit correctly follow the instructions:... -
