QRchive Pulse

Your septic panel deletes its own memory every few weeks. Pulse keeps it.

Drop in the download from an SJE Rhombus EZ Series panel and get a clean read on pump health, flow vs. design, and inflow & infiltration — on any phone or laptop, no install. Panel intelligence for septic systems.

The problem

The panel logs everything. Then it forgets.

Every EZ Series panel records pump cycles, run-time, and tank level — then overwrites the oldest data once its buffer fills (about three weeks on a busy system). The manufacturer's reporting software runs on Windows only and shows a raw event grid. Pulse turns the same download into answers, and merges every download into a permanent history the panel itself can't hold.

The stock reporting software

  • Windows-only legacy app
  • Raw event grid — you interpret it yourself
  • No trend analysis, no alarms, no flow-vs-design
  • History dies with the panel's rolling buffer
  • No client-ready report

QRchive Pulse

  • Any browser — phone, tablet, Mac, PC — offline
  • Pump health, flow, diurnal pattern, plain-language diagnostics
  • Flow vs. design ADF/DDF; inflow & infiltration analysis with rainfall
  • Merges every download into one permanent history
  • One-click client-ready PDF report
What it tells you

Read the system, not the raw log.

📈

Flow vs. design

Measured daily and peak flow against the system's design ADF/DDF — real occupancy load against the basis of design, not a guess.

💧

Inflow & infiltration

Overlay Environment Canada rainfall and test wet-weather flow against a day-of-week baseline — catch stormwater or groundwater leaking in, the costliest failure mode.

⚙️

Pump wear & duty

Seconds-per-dose trend, duty balance between pumps, short-cycling — turn reactive callouts into scheduled maintenance.

🕓

Permanent history

Each download merges and de-dupes into one continuous record — the long-term history the panel's rolling buffer erases.

🧭

Coverage & gaps

See exactly which days are missing and get a "download again by" date so history never silently disappears.

📄

Client-ready report

One-click PDF — KPIs, charts, diagnostics, coverage — to hand a client or attach to a file.

The dashboard, on real panel data.

Every panel below is a live screenshot of the actual tool reading a real two-month merged history — not a mock-up. Click any of them to open the same data yourself.

KPI cards: events held, average and peak daily flow vs design, data coverage, duty balance, tank level, CRC validity, and the download-again-by date
The read at a glance — flow vs. design, duty balance, coverage, and a "download again by" date computed from this system's own dose rate.
Plain-language diagnostic cards: pump duty balance, pump wear drift, short-cycling, level band, faults, missing days, and design-capacity headroom
Plain-language diagnostics — pump wear drift, short-cycling, duty balance, level band, capacity headroom, and exactly which days the buffer erased.
Daily throughput bar chart against design ADF and DDF reference lines, with buffer-gap days flagged in grey
Daily flow against design ADF/DDF — buffer gaps flagged, nothing hidden.
Tank level over time with alarm, override, enable, and redundant-off setpoint lines, beside cumulative pump run-time
Tank level on a true time axis with the panel's setpoints, beside lifetime run-time per pump.

Proven on a real system

A Vancouver Island campground, one month of data.

Built by a practicing BC wastewater engineer on one of their own client systems (May 2026). Every figure below is real, computed from the panel's own 4,080-event download.
