Katronic KATflow 170 Explosion-Proof Clamp-On Ultrasonic Flow Meter

Overview

The Katronic KATflow 170 is a fully explosion-proof clamp-on ultrasonic flow meter, certified to ATEX, IECEx, and EAC-Ex standards for permanent flow measurement in Zone 1 and Zone 2 hazardous areas. Built for corrosion-resistant, rugged operation under extreme environmental conditions, the Katronic KATflow 170 is available in an epoxy-coated, copper-free aluminium housing or a particularly robust stainless steel version built to the high standards of the offshore industry, and it covers a wide pipe diameter range from 10 mm to 3,000 mm with standard sensors rated from -50°C to +95°C.

As the official authorized partner for Katronic in Oman and the wider GCC, Seven Star LLC supplies the Katronic KATflow 170 to oil and gas operators, refineries, and petrochemical facilities across Muscat, Sohar, and Salalah where permanent flow measurement in certified hazardous areas is a non-negotiable safety requirement. Regional engineering teams benefit from genuine Katronic hardware, full Ex-certification documentation, and responsive local technical support backed by Seven Star LLC’s instrumentation division.

Measurement Principle

Like the rest of the Katronic KATflow range, the KATflow 170 uses clamp-on ultrasonic transit-time technology, measuring the difference in transit time between ultrasonic pulses travelling with and against the flow to calculate fluid velocity without any wetted parts or moving components. Because the transducers mount externally on the pipe wall, the KATflow 170 can be installed and serviced without breaking into the process line, an important safety and operational advantage in hazardous-area installations where hot work permits and process shutdowns carry significant cost and risk. The meter supports single-pipe measurement in two-path mode for improved accuracy under difficult flow conditions.

The explosion-proof housing and Ex-certified electronics of the Katronic KATflow 170 allow the transmitter to be installed directly within classified Zone 1 and Zone 2 hazardous areas, eliminating the need for remote-mounted electronics or additional barrier equipment in many installations. A keypad protected by a glass front allows the device to be operated directly from the outside of the enclosure without breaching the explosion-proof rating, while the IP68 stainless steel sensors are potted and fitted with extremely durable cable material to withstand the harsh conditions typical of offshore and onshore oil and gas facilities.

Engineering Design of the Katronic KATflow 170

The Katronic KATflow 170 is available in two explosion-proof housing variants: an epoxy-coated, copper-free aluminium housing suited to most onshore hazardous-area installations, or a particularly robust stainless steel version built in accordance with the high standards of the offshore industry. Where Ex-certification is not required, the aluminium housing is alternatively available with an IP68 protection rating, allowing for permanent submersion in water, making the KATflow 170 platform flexible enough to cover both certified hazardous-area duty and demanding non-hazardous submersible applications from a single hardware base.

Process communication on the Katronic KATflow 170 is handled via RS485, Modbus RTU, Profibus PA, and HART-compatible output, allowing integration into the distributed control systems and safety instrumented systems typical of oil and gas and petrochemical facilities. The transmitter is wall or pipe mounted and operates from mains power, available in AC or DC variants to suit different site electrical infrastructure. The pressure-sealed IP66 aluminium or stainless steel enclosure, combined with the potted IP68 sensors and reinforced cabling, gives the KATflow 170 the durability needed for continuous, unattended operation in demanding process environments.

Key Features

The Katronic KATflow 170 combines full Ex-certification with rugged mechanical design, and its feature set is built specifically around hazardous-area reliability.

• ATEX, IECEx, and EAC-Ex certified for permanent installation in Zone 1 and Zone 2 hazardous areas.
• Choice of epoxy-coated aluminium or stainless steel explosion-proof housing to suit offshore or onshore duty.
• Wide pipe diameter coverage from 10 mm to 3,000 mm with standard sensors rated -50°C to +95°C.
• Non-invasive clamp-on ultrasonic measurement with no wetted parts, moving components, or process interruption.
• IP68 potted stainless steel sensors with extremely durable cable material for harsh environments.
• Glass-fronted keypad allows safe operation without breaching the explosion-proof enclosure.
• Process outputs including RS485, Modbus RTU, Profibus PA, and HART-compatible communication.
• Optional IP68-rated non-Ex aluminium housing variant for permanent submersion applications.

Industrial Applications

The Katronic KATflow 170 is specified wherever permanent flow measurement is required inside classified hazardous areas, including upstream and downstream oil and gas facilities, refineries, petrochemical plants, tank farms, and offshore platforms. Its non-invasive clamp-on design removes the need to break into pressurized hydrocarbon lines for installation or maintenance, a significant safety and cost advantage in facilities where hot work permits and process isolation are tightly controlled. The stainless steel housing variant is particularly well suited to offshore platforms and coastal facilities where salt-air corrosion resistance is a critical specification requirement.

As the officially authorized partner for Katronic, Seven Star LLC distributes the Katronic KATflow 170 throughout the Sultanate of Oman and the broader GCC, supporting oil and gas operators, refineries, and petrochemical facilities across the Sohar and Duqm industrial zones with certified, hazardous-area flow measurement. Regional engineering teams sourcing Ex-certified instrumentation for new-build or brownfield projects benefit from local stock availability, genuine Katronic Ex-certification documentation, and direct technical support from Seven Star LLC’s instrumentation division.
