A liquid sensor business which effectively monitors risk of Legionella in water systems – massively reducing waste – has raised £870,000.

InferSens, based in Cambridge, utilises artificial intelligence and machine learning, alongside a small physical sensor, to non-invasively monitor the flow of any liquid in pipes.

The business is of particular interest to building owners who are legally required to scrutinise the flow of water in properties for Legionella, with a fixed monthly fee charged per sensor.  

Historically, checking for Legionella has involved the manual monitoring of water outlets, a laborious and environmentally wasteful process.   

RO Capital Partners invested alongside the Oxford Innovation Fund and Bruce Melizan, former MD of Interserve’s support services division.  The capital will bring the product to market and grow its presence.

InferSens says the tech will significantly boost environmental and sustainability scores for its users.

“I am delighted that InferSens has been oversubscribed for its funding round; a real recognition of our cutting edge technology at the interface of IoT sensing and on-device machine learning,” said CEO Colin Payne. 

“This critical milestone for the business will enable the commercial launch of our ML-powered flow and temperature sensing technology, initially targeting the major global challenge of keeping buildings safe from Legionella.

“We have been fortunate to attract a stellar mix of engaged investors including experts in the fields of mobile communications, property development, facilities management, corporate finance, and tech startups, who are eager to work with us to help us achieve our ambitious goals.”

Edward Rowlandson, group MD at the RO, said: “As owners of a diverse and large property portfolio, InferSens immediately stood out.

“We are excited to invest in the business, and its first class management team, to bring a product to market which we believe will transform facilities management, and for which we can see a number of wider applications, setting new levels of environmental efficiency and waste reduction.”
