Metering Non-Revenue Water

Non-revenue water (NRW) refers to the difference between the amount of water a utility produces and the amount it bills to customers. This means it’s water that is lost or unaccounted for within the system before it reaches a paying consumer. 

• Real losses: These are physical losses, primarily due to leaks in pipes, mains, and service connections. 
• Apparent losses: These include metering inaccuracies, unauthorized consumption (theft or illegal connections), and unbilled authorized uses (e.g., firefighting, flushing). 
• Unbilled authorized consumption: This is water used for legally sanctioned purposes that are not billed, such as firefighting or system flushing. 

The portable ultrasonic clamp on flow meter can be used to reduce physical losses and apparent losses.

Leak detection using the adjustable zero cutoff level and triple reflex mode for very low flow readings to stave off real losses and hunt down small leaks in the system.

Inline meter verification for meter inaccuracy reduction to reduce apparent losses. Setting up our clamp on flow meter next to an inline meter to verify the readings are correct.

Sub-Metering lines that branch and have no metering.

Reducing non-revenue water often pays for the technology required to reduce it. ROI can be measured in real-time. Feel free to contact us with any questions about your application. We have a meter for every situation and budget.
