After rigorous research and design, in June 2019, Coltraco are proud to release a more accurate, reliable and flexible ultrasonic flow meter: Portasonic 2.FL0.

1. Accurate – the Portasonic 2.FL0 is accurate to +/-1% accuracy
2. Reliable – the Portasonic 2.FL0 is calibrated to ISO17025 standards
3. Flexible – the Portasonic 2.FL0 has 3 modes of operation, making it suitable to different environments

The Portasonic® 2.FL0 ultrasonic flow meter is used to measure flow rates of clean liquid in pipe. The device comes with clamp on transducers for non-invasive measurement. The Portasonic® 2.FL0 utilizes two transducers, one that acts as ultrasonic transmitters and the other a receivers. There are three principles of operation; V-method, W-method or Z-method which refers to transducer positioning. The software calculates the time it takes for the ultrasonic pulse to pass from the transmitter to the receiver, which is dependent on the flow rate.

With no moving parts and an easy digital set up mean it’s a cost effective and time effective maintenance solution. Reduction of maintenance time and cost is a driving factor within any business operation with pipework installed. Accurate flow data provides the chance to make energy saving measures by fine tuning the systems.

Portasonic® 2.FL0 can be used for spot checks, using an internal, rechargeable battery or for extended continuous operation as a 4-20mA flow transmitter with AC power input. The ease of use and accuracy of Portasonic® 2.FL0 allows for improved business continuity and safer buildings and industrial facilities across a variety of industry verticals. With the ability to conduct spot checks at mandated intervals, full integrity of pipework can be ensured.

UPDATE: February 2021, Coltraco Ultrasonics launched a THIRD GENERATION ultrasonic handheld flow meter. Same name, same concept, but completely new design!

We have made it more ergonomic, easier to use and much more compact. The sensors are simpler to attach and the whole package comes in a much lighter package, making it easier to transport.Keywords: Ultrasonic flow meter, ultrasonic portable flow meter, portable ultrasonic flow meter, ultrasonic monitoring equipment, ultrasonic measuring devices, ultrasonic monitoring and measuring equipment
