TRANSCRIPT
Accurate water measurement is the means by which water utilities produce revenue to
cover expenses, charge consumers equitably, prevent waste of water, and
minimize wastewater loads

Compared to un-metered systems, consumption is reduced 20% to 50%
Eliminates waste and lowers operating costs
Metering provides “fair share” cost to consumers
Accurately measures water usage
Less than 1% of all the water on Earth is freshwater available for human consumption (waterinfo.org)

420 RDMFully Integrated Remote Disconnect Meter (RDM)
Enables municipalities remotely manage water services from the office through advanced metering infrastructure (AMI) or from the safety of their vehicles
420 RDMBenefits
Improved customer service
Improve employee safety & reduce operational costs
Reduce carbon footprint
Customers will not have to wait for service crews to arrive to turn on their water
Enables municipalities to manage services without dispatching service crews. Municipalities can also manage services safely from vehicles
Remote management of water services saves fuel
420 RDM
A diaphragm design valve that opens/closes using water pressure for low friction loss and low energy use
User friendly design for simple service and in-line maintenance
Engineered materials that provide chemical resistance for long life
Excellent regulation performance under low/high flow conditions
Integrated nutating disk PD meter for extreme low-flow accuracy
420 RDM provides optimum performance and efficiency over an expected 20-year life cycle with features that include:

Meter type is important when
considering low-flow accuracy in which
performance varies
If Salt Lake City changed from Piston
meters to Disk meters the result would be
an increase of 239 mil gal or $430,000

Vertical Turbine: Replaces Applications for Positive Displacement Compound Turbine
Horizontal turbine meters need straight pipe to provide the necessary water pattern for accurate measurement.
The MVR creates it’s own water pattern by turning the water inside the meter.
Because of this, the MVR does not require straight pipe before the meter!
No Straight Pipe Needed!
