Introducing: Flow.Watch
Flow.Watch

We are pleased to announce the launch of Flow.Watch, our unique, patented solution for fire supply surveillance.

Combining advanced temperature analysis with advanced telemetry options, including NBIoT and LTE-M (Cat-1), we have developed an economical method to monitor fire supply flow.

As well as monitoring private fire supply systems, Flow.Watch is also suitable for monitoring public fire supply hydrants, helping to identify thefts from the water network.

As well as increased unaccounted for water, misuse of fire hydrants can cause pressure transients and discolouration of the water supply.  Flow.Watch is a simple, non-intrusive and covert method of monitoring hydrant usage.

The Flow.Watch system identifies and categorises fire supply flow into leakage, test use and intermittent use.  This enables water companies to identify the fire supplies from which water is being used or lost, helping to account for water consumption and determine whether apparent DMA night flow loss increases are because of customer use or customer-side losses.

Simple to install and with remote set up, Flow.Watch is a versatile solution that provides a non-restrictive alternative to metering.

In a recent case study, Flow.Watch was installed to monitor the fire mains systems of 118 large industrial facilities belonging to one of the UK’s largest water companies.

Over an 8 week period, almost one third of these sites (36) were found to have regular water usage events from the unmetered fire supply, while at 30% of sites some form of leakage was discovered.

Flow testing in the fire supply of one property discovered usage of 375 litres/minute.  With weekly tests lasting on average 38 minutes, we estimated up to 230,000 litres/week of usage from fire supply testing alone.

Flow.Watch is a versatile, cost-effective solution for fire supply surveillance.  For more information about Flow.Watch please click here.
