The measurement problems

Non-revenue water

You pumped 100 units. You billed for 78. Where did 22 go? Answering that means metering successive segments of a network and hunting differences — and you cannot shut a transmission main to install meters, so every one of those measurements has to be non-invasive.

The differences you are chasing are often small, which is why velocity resolution matters. The Ultraflux UF801-P resolves down to ±0.03 ft/s specifically for leak work.

Night flow analysis

A district metered area runs hard at 7am and nearly still at 3am. The 3am number is the one that tells you whether you have a leak — a district with no leaks approaches zero overnight; one with a leak does not.

This is where turndown ratio stops being a datasheet curiosity. A meter that goes blind at low flow does not announce it. It reports zero, or it reports noise, and both look plausible. The METRI IC-UPF offers 1:2500, which is what you want on a permanent DMA meter.

Verifying meters you have stopped trusting

Every utility has revenue meters that have been in the ground for fifteen years and nobody quite believes. A portable clamp-on meter is an independent, non-invasive second opinion — without pulling the meter, without a shutdown, without a bypass.

Pump station performance

Pumps degrade. A pump delivering 15% below its curve is costing you energy every hour and nobody notices until it fails. Clamp on, compare against the curve, move to the next station.
