Micronics portable flowmeter verifies flow measurements at major London airport

An independent building engineering and business processes specialist in whole system building service engineering has used a Micronics Portaflow 330 from June to Dec 2017 to verify the readings on installed meters at a major London airport. This was for compliance reasons as the regulation of potable and borehole water is key to the airport’s agenda.

Alun Otley, Managing Director of ARO Consultants purchased the unit after consulting with one of his engineering team, who recommended the Micronics unit which he was familiar with. “We now use the portable unit all the time, particularly where there is a need to verify installed gauge flow rates. We have also used it to verify data against the accuracy of harvesting spring water and in heating and cooling circuits to reduce over pumping. We would highly recommend it.” ARO are based in Middlesex and specialise in complex buildings and aviation in the London region.

The specialist clamp-on flowmeter is used for clean liquid monitoring. Because measurement is non-invasive it can be used without having to cut into the pipes and, consequently very limited downtime is necessary, crucial in 24 hour operations like an airport. There is also appreciably less disruption than when installing an alternative in-line meter. The Portaflow is portable and can therefore be easily transported to multiple locations. It is easy to use and offers continuity and long term reliability. It is robustly constructed and provides a quick and reliable means of measuring flow accurately. The device is very simple to use – there is no overhead for additional fittings, plant modification, or retro-fit expenditure. Also there is no contact with fluid so there is no risk of contamination of the process fluid and possible exposure of the monitoring equipment to corrosive or toxic liquids.
