In accordance with BS9990:2015 a regulations for fire hydrant and pump testing, the 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 must 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 a wet fire mains and pumped water pipelines to fail due to blockages.
The ability to conduct spot checks on the wet fire mains and pumped waterlines at mandated intervals ensures the full integrity of the sprinkler system. The ease of use and accuracy of Portasonic® allows for improved business continuity and safer office buildings and industrial facilities across a variety of industry verticals. Reducing maintenance downtime reduces disruption to a commercial operation at the same time as improving life safety particularly in high risk environments and industries will help to further educate the industry and reduce fire incidents.
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 an ultrasound transmitter and the other as a receiver. There are three principles of operation; V-method, W-method or Z-method referring to transducer positioning based on pipe sizes. The internal software calculates the time it takes for the ultrasonic pulse to pass from the transmitter to the receiver, which is dependent on the liquid flow rate.
With no moving parts and an easy digital set up, 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 the systems.
Portasonic® 2.FL0 can be used for 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.
