The Permaflow® is a fixed, clamp-on, ultrasonic transit time flow and heat meter that is non-invasive for measuring the flow rates of liquids containing less than 10% of gas/solid contents. It is mains powered, designed for 24/7 monitoring and is accurate to +/- 0.5% of measured value under ideal conditions.

P/N: 3578010-FLOW

The Portasonic® 2.FL0 is a handheld, clamp on, non-invasive ultrasonic transit-time flowmeter designed to measure flow rates liquids in pipes accurate to +/- 0.5% without requiring any invasive installation. It works on a wide range of liquid types containing less than 10% solid content, and pipes from DN15 – DN2500 made from different metal or plastic materials.

P/N: 2618949-PSO

Portable instrument for assessing watertightness, locating and quantifying water leaks, and predicting water flow rates. 

The Portascanner® WATERTIGHT PRO is a unique ultrasonic technology from Coltraco Ultrasonics capable of identifying the exact location of any leak site within a structure, measuring the physical size of the leak, calculating the rate of water flow through it, and providing the ability to record and report observations.

Introducing the Portascanner® WATERTIGHT PLUS, the world-leading fully ABS Type-Approved & RINA-Accepted, the watertight integrity tester for inspecting watertight and weathertight seals on ships and marine structures such as warships and offshore oil & gas platforms.

The Portascanner® WATERTIGHT PLUS offers the functionality and display, all packaged into a smart, ergonomic, and rugged enclosure. With the implementation of three testing modes, the user has much greater control when testing a large variety of hatch covers and watertight structures.

A new user interface upgrade now allows the user to switch between Linear, Decibel (dB) and an Open-Hatch mode (specific for testing hatch covers) displaying the percentage leak, making it even more efficient and user-friendly than its predecessor, the Portascanner® Watertight.
