Sentech AS

What Sentech AS does

Sentech AS is a privately held Norwegian instrumentation company founded in 1995 and headquartered in Oslo, specializing in measurement sensors, monitoring systems, and electrical instrumentation for the global oil and gas industry. The company designs and manufactures products based on its patented SeCaP (Single Electrode Capacitance) sensor technology, a single-electrode capacitance probe developed in cooperation with SINTEF and Norsk Hydro (now Equinor) research centers that detects water content in hydrocarbons by exploiting the large permittivity differential between water (~80) and hydrocarbons (2.0–2.3). Sentech has supplied more than 2,500 SeCaP sensors worldwide since inception.

The product portfolio centers on the Level Profiler — a string of SeCaP sensors that provides real-time, high-resolution visibility into fluid layers (gas, foam, oil, emulsion, water) inside separators and vessels — and the Water Cut Meter, which uses multiple SeCaP sensors for full-bore inline measurement across the 0–100% water range. The portfolio extends to subsea variants including the Subsea Water Cut Meter, Subsea Water Leakage Detector, and Subsea HV Penetrator. SeCaP sensors are compact (under 1 inch), non-intrusive, handle temperatures up to 225°C and pressures up to 450 bar, and require no radioactive sources, differentiating them from nucleonic instrumentation.

Sentech sells custom-engineered capital equipment directly to enterprise oil and gas operators — including IOCs (Shell, BP, ExxonMobil, TotalEnergies), NOCs (Equinor, Petrobras, ADNOC), and independents (Suncor, AkerBP, Piper Energy) — through a global field sales motion supplemented by technical sales consultation, industry events, and a content-driven marketing engine. Revenue is generated via hardware sales of sensors and integrated systems, supplemented by installation, maintenance, and technical consulting services. The company holds ATEX and IECEx hazardous-area certifications as well as ISO 9001:2015 quality management certification, and operates as an unlisted Norwegian private limited company with no disclosed funding rounds, revenue, or headcount.

Core offering

Sentech AS designs, manufactures, and sells proprietary SeCaP (Single Electrode Capacitance) sensor-based measurement instrumentation — primarily level profilers and water cut meters — that enable non-intrusive, real-time monitoring of water content in hydrocarbons for the global oil and gas industry. The portfolio also includes subsea-specific variants (subsea water cut meter, water leakage detector, HV penetrator) and related installation and support services.

Product overview

Sentech AS is a leading provider of level profilers and water cut meters to the global Oil & Gas industry since 1995. The company's product portfolio centers around the proprietary SeCaP (Single Electrode Capacitance) sensor technology, which enables 'see-through walls' measurement of water content in hydrocarbons. The core products include the Level Profiler (a string of SeCaP sensors providing virtual vision into separators and vessels), the Water Cut Meter (inline measurement of 0-100% water), and their subsea variants (Subsea Water Cut Meter, Subsea Water Leakage Detector, Subsea HV Penetrator). These products share the common SeCaP technology platform and can be deployed individually or in combination for comprehensive real-time monitoring of water in oil processing applications across upstream, midstream, and subsea environments.

Functional benefit

Brands

• SeCaP: Single Electrode Capacitance sensor technology - the core technology platform used in Sentech's level profilers and water cut meters. SeCaP sensors can measure less than 1 inch in diameter and are designed to operate at temperatures up to 225°C.

Products and services

• Level Profiler A 'virtual window' into separators and vessels that embeds a string of SeCaP sensors to provide real-time, high-resolution view of gas, foam, oil, emulsion, and water layers, allowing operators to prevent upset conditions and optimize separation and oil throughput. Sold to oil and gas operators and EPC/integrator customers.
• Water Cut Meter Inline measurement device using multiple SeCaP sensors to measure water content across the full 0–100% range in any pipe diameter without flow restrictions or pressure drop; detects well-mixed, separated, or sluggish flow and measures % water in two-phase and multiphase flow. Sold to oil and gas operators and EPC/integrator customers.

• SINTEFcoreStrategic or Co-development Partner · 1 January 1995In the early years after the company was established in 1995, Sentech AS cooperated with SINTEF research center in Trondheim, Norway to develop and patent the SeCaP sensor technology.
• Norsk Hydro Research Centre (now Equinor)coreStrategic or Co-development Partner · 1 January 1995Sentech developed its SeCaP technology in close cooperation with Norsk Hydro Research Centre in Porsgrunn (now one of Equinor's seven global research centers). Throughout its history, most Sentech products have been developed and tested at this research facility.

Direct peers

• Agar Corporation: Agar is a long-established specialist in multiphase flow and water-cut measurement for oil and gas production. It is explicitly named by Sentech's customers (e.g., Suncor) as a direct alternative, making it the closest comparable in product category and target customer.
• Phase Dynamics: Phase Dynamics manufactures capacitance-based water-cut analyzers for crude oil and produced water. It directly overlaps Sentech's core Water Cut Meter product line and is named alongside Agar by Sentech's oil sands customers as a competing supplier.

Broad incumbents

• Emerson (Rosemount): Emerson's Rosemount division supplies a broad portfolio of process instrumentation including level, flow, and water-cut measurement for oil and gas. It competes with Sentech as part of a much wider measurement and control portfolio and serves the same IOC/NOC/EPC customer base.
• Endress+Hauser: Endress+Hauser is a global leader in industrial process instrumentation, offering level, flow, and analytical measurement products for oil and gas processing. It addresses the same separator and process applications as Sentech but as one of many product categories.
• Honeywell Process Solutions: Honeywell provides process measurement and control solutions across upstream, midstream, and downstream oil and gas. Its instrumentation portfolio overlaps with Sentech's water-cut and level measurement applications on shared enterprise customer sites.
• Schlumberger (SLB): SLB's digital and integration division offers multiphase flow meters and production surveillance instrumentation. It targets the same upstream and subsea customers and competes with Sentech especially on integrated subsea production monitoring projects.
• ABB: ABB supplies measurement products, analytics, and control systems for oil and gas processing. Its instrumentation competes with Sentech in level and process monitoring on platforms and in subsea applications.
• Yokogawa Electric: Yokogawa offers industrial process instrumentation including flow, level, and analytical sensors used in oil and gas separators and processing. It serves overlapping upstream and midstream customers with broader portfolio coverage.
• Siemens Energy: Siemens Energy supplies measurement, controls, and electrification for oil and gas facilities. Its instrumentation portfolio is broader than Sentech's but targets the same process monitoring use cases on customer sites.
• Roxar (part of Emerson): Roxar, an Emerson brand, provides multiphase flow meters and reservoir monitoring instrumentation for upstream oil and gas. It is a relevant competitor in the multiphase and water-cut measurement category where Sentech positions its Water Cut Meter as a lower-cost alternative.
