Oxygen flow rate and line pressure monitoring and alerting

FLO2 helps you analyse and optimise your hospital’s oxygen use with greater accuracy than ever before
You’ll be alerted by email and text when oxygen supplies are approaching maximum capacity so that you can respond quickly

Hospital managers rely on having timely, detailed information on oxygen usage to help them plan.

Flow meters can be a valuable tool to assist with this. But the traditional way of tracking them using the Building Management System can be restrictive and inconvenient.

That’s why we developed FLO2 for speedy, agile, round-the-clock oxygen monitoring and alerting.

If you don’t have them already, we start by fitting one or more oxygen flow meters—either an ultrasonic clamp-on or a permanent plumbed-in model. The FLO2 box connects to the flow meter.

Every 5 seconds FLO2 reads the 4-20ma output from the meter and transmits the data back to SHJ servers using the mobile phone cellular data network. The flow rates of each meter, along with a totaliser, are displayed in K’nect, SHJ’s cloud-based customer data portal which can be viewed via the web on any device. Graphs are available to show usage over the last hour, 6, 12 or 24 hours, one week or one month.

FLO2 can also read and relay oxygen line pressure. This is achieved by plugging a pressure transducer into a NIST connector and hard-wiring it into FLO2. This provides live data showing how line pressure is responding to system demand.

Trigger points are set at pre-set pressures and flow rates, allowing us to send text or email alerts to the relevant people.

K’nect is free to all our customers with a maintenance contract, up to a maximum of 5 users.

A typical installation of clamp-on flow meters and FLO2 can be carried out within about 4 weeks.

We will demonstrate FLO2 on your MGPS using portable clamp-on meters so you can see for yourself the value of instant, easy access to such vital data.


FLO2 was the subject of an in-depth article in the June 2021 issue of the Health Estate Journal. Click here to read about the development of the product and how it is helping one of our largest customers, Imperial Healthcare NHS Trust, manage their oxygen supplies.
