What are the advantages of ultrasonic flow meters?
The Portasonic 2.FL0 is an accurate, reliable and robust portable ultrasonic flow meter.
The ability to conduct spot checks of systems at mandated intervals ensures the full integrity of sprinkler systems. The ease of use and accuracy of Portasonic® digital liquid flow meter allows for improved business continuity and safer office buildings and industrial facilities across a range of applications. Reducing maintenance downtime reduces disruption to a commercial operation, at the same time as improving safety, particularly in high-risk environments, and industries. This will help to educate the industry further and reduce fire incidents
With no moving parts and an easy digital set up for liquid flow measurement, it’s a cost 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 sprinkler systems.
Portasonic® 2.FL0 can be used for measuring flow in a pipe, to spot checks using the 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, flow rates in pipework can be maintained to ensure they meet the required standard.
7 key benefits of the Portasonic® 2.FL0
1. Non invasive flow measurement from outside of a pipe as a clamp on flow meter.
2. Long term battery life, light weight, compact and reliable.
3. Robust: prevent water ingress into the charging port with a watertight flap.
4. Easy to use with simple set up thanks to unique clamp-on design
5. Variable use in different environments: 3 different modes of operation and sensors for pipe sizes.
6. Allows pipe wall integrity testing by the ability to conducts spot checks at mandated intervals.
7. Cost saving: cost and time effective with easy digital set up.
What does a flow meter do?
The Portasonic® 2.FL0 measures flow rates of clean liquid in pipes (liquid with not more than 5% solids or 2% gas).
How does an ultrasonic flow meter work?
The portable transit line ultrasonic flow meter, Portasonic® 2.FL0 comes with clamp on ultrasonic transducers for non-invasive measurement. The ultrasonic flow meter principle is simple, the unit uses two sensors, one that acts as ultrasonic transmitters and the other a receiver to measure flow. There are three methods 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.
Is the Portasonic® 2.FL0 a high accuracy flow meter?
The Portasonic® 2.FL0 is a highly accurate liquid flow meter with an accuracy of +/-1% of reading at rates > 0.2 m/s, and the meter calibration takes place at an ISO 17025 certified lab.
What is the benefit of non-invasive testing?
The benefit of the Portasonic 2.FL0 is non-invasive testing with clamp-on external sensors: stopping the difficulties of cutting sections of pipe, risking pressure drop or contamination.
Is the Portasonic 2.FL0 a high temperature flow meter?
For fluid temperature exceeding 90°C, high temperature sensors are available up to 160°C.
What are the available ultrasonic flow meter sensors?
There are a range of sensors available to cater for small, medium and large pipe sizes. The pipe diameter range runs from 15mm-700mm. Please ask for the wide range of sensor options.
How do you measure water flow?
As mentioned above, depending on the application and flow profile, the flow sensors can be mounted in the following ways:
i. V-method: the ultrasound transverses the pipe twice
ii. W-method: the ultrasounds transverse the pipe four times
iii. Z-method: transducers are mounted on opposite sides of the pipe and the ultrasound transverses only once
The modes are automatically selected by the liquid flow meter and are also user selectable.
Why buy the Portasonic® 2.FL0 and not a cheaper unit?
The ultrasonic flow meter price is related to its key features: that is calibrated to ISO17025 which is a better calibration standard, hence more reliable.
Demonstration of the Portasonic® 2.FL0?

What are the applications of the Portasonic® 2.FL0?
There are a range of applications for the Portasonic® 2.FL0. Some of them include fire sprinkler systems, leak detection, marine maintenance, balancing systems and hydraulic system testing.
Testing fire hydrants & pumps
In accordance with BS9990:2015 a regulation for fire hydrant and pump testing, the transit time Portasonic® 2.FL0 flow meter is a simple & accurate means to measure and record flow rates in wet fire mains and pumped water pipelines.
For pressure regulating valves, according to BS9990 there is an allowable tolerance for flow and pressure at the landing valve of (750 ±75) L/min at (8 ±0.5) bar. Equally for pumps for wet risers, the pumps have to be capable of delivering 1 500 L/min which is enough to supply each of two fire service hoses with 750 L/min. For water tanks an on-site supply of stored water must be capable of supplying enough water to provide two landing valves with not less than 750 L/min each for at least 45 minutes.
It is essential that wet risers are operational in the event of a fire. The flow is calculated so that there is always enough to control a fire taking into account the size and construction of the building and the goods stored in it, or its use. Accurate flow data provides the chance to make energy saving measures by fine tuning the systems. Corrosion and obstructions can cause wet fire mains and pumped water pipelines to fail due to blockages.
