ZT-100 F-Series
Flanged water cut analyzer with full radiographic weld inspectability
Weld Neck Flanged Design
The ZT-100 F-Series uses weld neck flanges for both the process connection and the sensor entry point. This design facilitates radiographic (X-ray) inspection of all welds — a significant advantage for quality assurance and pressure integrity verification. The spool section is 100% compatible with main line piping specifications, ensuring seamless integration into any pipeline system.
The flanged probe, manufactured from 316L or other austenitic stainless steels, provides isokinetic measurement — the sensor geometry introduces no flow distortions that could lead to measurement errors. Available from 4″ to 48″ nominal sizes with pressure ratings up to Class 1500#.

Key Features
Weld Neck Flanges
Both process connections and sensor entry use weld neck flanges, enabling full radiographic (X-ray) inspection of every weld for verified pressure integrity.
Isokinetic Measurement
The flanged probe geometry introduces no flow distortions, eliminating measurement errors caused by flow profile disruption.
Blow-Out Proof Sensor
Self-jamming sensor design ensures the probe cannot be ejected under process pressure, providing inherent safety without secondary retention.
Optional Integrated Static Mixer
FM-Series variant includes an integrated static mixer upstream of the sensor for improved measurement accuracy in stratified flow conditions.
Optional Density Compensation
Built-in density compensation corrects for variations in crude oil density and temperature, improving accuracy across changing process conditions.
Hazardous Area Certified
ETL US/CAN, ATEX, and GOST certified for installation in explosive atmospheres across global jurisdictions.
