  1. Coupled with AquaMonitor computer to track facility water use for septic review 4 Star Review

    Posted by on 9th Oct 2017

    NOTE1: We used this meter instead of the one that normally comes in the Aquamonitor package (see comments below) because we needed a vertical mount - we could not easily adapt to a typical horizontal meter.

    NOTE2: This meter works differently than most others (positive displacement method) so it makes a rather loud clacking noise as water flows through it. Not ideal if you need to place this close to an office or other area that requires quiet.

    We coupled this meter with the Aquameter wireless computer that Flows sells, and it's doing a great job at tracking our hourly/daily facility water use so we can apply for a septic capacity increase. Normally the septic analysis requires reading the meter daily at the same time, but we don't have staff on site regularly enough to do so, so we couldn't collect required info to apply for an analysis. This combination finally collects the data the Sewage Enforcement Officer requires.
