ZT-100 I-Series Flanged
Permanent flanged insertion probe for high-pressure pipelines
Flanged Insertion Probe
The ZT-100 I-Series Flanged is a permanently installed insertion probe designed for water cut measurement in large-diameter, high-pressure pipelines. The probe is bolted directly to a flanged nozzle on the pipe, providing a robust, leak-tight installation rated up to ANSI Class 1500 (250 barg).
Without the complexity of a retraction mechanism, the flanged version offers a simpler, more compact installation with the same high pressure capability. The probe enters through a 2" or 3" nozzle and is designed for line sizes from 12" to 48". Ideal for permanent installations where the probe does not need to be removed under pressure.
Key Features
High Pressure Rating
Rated up to ANSI Class 1500 (250 barg), suitable for high-pressure trunk lines, export pipelines, and wellhead applications.
Simple Installation
Bolts directly to a flanged nozzle. No retraction kit, ball valve, or packing gland required.
Adjustable Depth
Probe length specified at order to position the sensor at the optimal measurement point in the pipe cross-section.
Hazardous Area Certified
ETL, ATEX, and GOST certified for hazardous area installations in explosive atmospheres worldwide.
Robust Construction
316L stainless steel standard with optional Duplex and Monel. PEEK seals and electrical insulators. IP66 / NEMA 4X & 7 rated enclosure.
Standard Communication
4–20mA + HART analog output. Loop powered at 24VDC with 0.66W max power consumption.
