The Problem Unaccounted-for Water
Water meters are not designed to measure volumes
of water at very low rates.

The Solution UFR (Unmeasured Flow Reducer)
The UFR captures low flow water and forces it
through the meter in a way that causes nearly
every drop to be registered by the water meter.

UFR can increase the measurement of billable
water between 5 and 10

Where Does The Water Go?
Ever wonder where all the water goes in a typical
home? Most of it goes down the toilet.
Surprisingly, very little of it is used for
actual drinking. These statistics do not account
for water used outdoors. 1) Toilets 28 2)
Clothes Washers 21 3) Showers and Baths 17
4) Kitchen and Faucets 20 5 ) Leaks 14

How does the UFR work?
17
UFR Principle of Operation
The UFR begins to operate at very low flow rates
and creates pulses of flow that the water meter
can measure.
Due to the change in the mode of water flow to
pulses, the UFR enables the water meter to
measure low flow rates.
