Large Commercial Spectrum Meters

– Performance Examples

Metron Spectrum Single-Jet Meters give utilities the ability to measure 1/4 gpm flows (and below) on 1 1/2” and 2” meters accurately. On average, the extended low flow yields an extra 10% – 20% revenue over conventional displacement meters. With the normal 1 ½” and 2” commercial services using 100,000 gallons per month or more, the Metron Spectrum Single-jets can yield an average $50 – $100 per month in additional water and wastewater revenue. The additional revenues generally pay for the meters in 1 – 2 years.

The smaller commercial meters have always been the forgotten sizes in US water utilities. Our utilities demand 3/4 gpm low-flow accuracy from our residential meters.

Historically, they demanded 1/4 gpm low end accuracy from the 3” and 4” compound meters. But on the 1 1/2” and 2” meters, utilities were forced to accept 1 ½ gpm and 2 gpm low flow accuracy. Recent innovation in flow profiling shows a very significant low flow usage below 1 gpm on these services annually.
