Coltraco Ultrasonics has launched the second generation of its ultrasonic flow meter. The 2018 model has upgraded from the original Portasonic in terms of aesthetics, accuracy and ease of use.
The Portasonic 2.FL0 ultrasonic flow meter is used to measure flow rates of virtually all non-aerated liquids (water/glycol/oils) in metal or plastic pipes from 12 mm to 4,570 mm diameter.
The device comes with clamp-on transducers for non-invasive measurement, one of which acts as the ultrasonic transmitter and the other as the ultrasonic receiver. There is no need to cut sections of pipe, which can lead to pressure drop or contamination.
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.
According to Coltraco Ultrasonics, there are no moving parts and the device has an easy digital set up.
The Portasonic 2.FL0 can be used for spot checks, using an internal, rechargeable battery or for extended continuous operation as a 4-20 mA flow transmitter with AC power input.
Business, operational and technical issues impacting the crude, product and chemical tanker trades will be discussed in London at the Tanker Shipping & Trade Conference, Awards & Exhibition, 20-21 November 2018.
