ZT-100 F-Series

The ZelenTech F-Series is designed to enable usage of spool sections 100% compatible with main lines while the flanged probe (316L or or other austenitic steels) will provide an isokinetic measurement (i.e. it does not create flow distortions leading to measurement errors).

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.

New: For large sizes we now give the option of utilizing the retractable I-Series probe instead of the traditional F-Series flow-aligned probe. Trade-off is that the unit will not be fully iso-kinetic, however for large pipe lines servicability without removing the main spool may be of greater value.


The ZelenTech ZT-100 F-Series can optionally be fitted with an integrated Static Mixer (FM-Series). The mixer will ensure that a well mixed and homogenized stream will reach the sensor. We configure mixer elements and spacing in accordance with standards such as ISO 3171 and API MPMS8.2 to ensure that the sensor will see a truly representative view of what is going on in your pipes.
