ZelenTech ZT-100 Watercut Monitors (also known as BS&W, OWD, WFM or Water in Oil Analyzers) offers you unmatched flexibility as we offer virtually unlimited number of configurations.
The ZT-100 Series of Watercut Meters can be installed inline, in bypass or as insertion. Built to any piping spec in the materials of your choice. 1 inch or 48 inch, we cater for all sizes.
The ZelenTech ZT-100 Watercut Monitor determines the percent watercut in an oil emulsion without requiring the physical separation of the fluids. The emulsion stream is continously monitored for capacitance and converted into percentage of water by the Watercut Monitor logic.
The Zelentech Watercut meter measures water in oil primarily in crude oil and is used in applications like fiscal metering, desalting, export metering, process control, on test separators, on- and offloading, etc.

Design and Integrity
The ZelenTech ZT-100 Water Cut Meters are built to strict standards.
Ability to accomodate a vast variety of Piping Specifications ensures
that the meter becomes an integral part of the piping system and
not a weak link.
ZelenTech’s ISO9001 quality system is able to accomodate any
customer requirements for documentation, material traceability and
The ZT-100 Water Cut Meter can be supplied with built in Static Mixer
providing a well conditioned stream both for inline measurement and
Designed in accordance with standards such as API 8.2 and ISO 3171.
The ZelenTech ZT-100 Water Cut Meter is designed around reliable capacitance technology. We have added decades of knowledge and experience to overcome problems normally associated with capacitance probes. The ZT-100’s built in logic will compensate for the vast temperature effects in the dielectric constant of the water while recognising the much smaller effects on the dielectric constant of the oil.
The ZT-100 is a loop powered Intrinsic Safe device with HART Interface. All setup can be done from a remote location using a dedicated PC interface.

Stream conditioning is the key to high accuracy water cut metering.
The effects of an unconditioned 2-phase stream renders the reading
of any high accuracy meter very questionable. The stream through
the sensor, be it direct or via a by-pass, must be representative of the
full flow. Our engineers will take a look at your complete setup and
provide advice and guidance so that the sensor will get a representative
The ZT100, correctly installed with proper stream conditioning, can be
expected to achieve the following accuracy:
± 0.01% up to 5% water cut
± 0.1% up to 5% and 10% water cut
± 0.2% between 10% and 25% water cut
± 0.5% between 25% and 50% water cut
± 1% between 50% and 100% water cut
Close correlation between lab and an online meter, no matter the
working principles of the meter, can only be achieved once the stream
is properly conditioned and the comparing sample is taken at the
same spot. Requirements of standards such as ISO3171 or API 8.2
must be followed to achieve correlation.
Our specialty is to provide complete solutions where we do not only provide you with a sensor, but also make sure that the
sensor receives a representative stream. We can supply full bore spool pieces designed to have the sensor on a by-pass or directly

New advanced proprietary Temperature Compensation Algorithm provided for new units. No more 2 point temp factor needed, the ZT-100 will temperature compensate automatically. Simply select your oil type in the ZelenTech ZT-100 Interface Software (HART or RS-232) and temperature compensation will work over the full temperature range, no matter the water content.
