CAPMAC

Is your plant healthy? Watch it, plainly.

CAPMAC checks valves and loops, city water and buildings with checks that each passed a fair test. Real data comes first on this page; simulator results come after, labelled quietly.

The engine

Remaining life

Every app has a Remaining life tab: how long until an indicator reaches its limit, as an approximate range with the limit and its source, never a single date.

Live checks

Every reading goes through checks that each passed a fair test before they may raise an alarm.

Valves and loops

Control valve

We watch: Sticking, jams, leaking seats, plugged trim, wear.

22checks working

REAL

Real Bauer/SACAC loops: all 3 sticking loops flagged. Small sample; trial on your own records recommended. No licence stated: shown one-to-one only; do not copy or forward.

Open in the app

Positioner and air supply

We watch: Air supply loss, miscalibrated travel, diaphragm leaks.

6checks working

OWN SIMULATED

Passed on our own simulated valves; no real or outside-simulator pass yet.

Open in the app

PID control loop

We watch: Oscillation, windup, saturation, manual mode, sluggish response, wrong set point.

24checks working

OWN SIMULATED

Sluggish-loop and hidden stick-slip checks passed fresh own-simulated tests; no real-data pass yet.

Open in the app

Water

District meter zone

We watch: Night flow, bursts, meter drift, theft, repairs confirmed.

48checks working

REAL

Real data from Yorkshire Water: repairs confirmed 0.30 vs placebo 0.03 on one test, 0.30 vs 0.05 on the next. Alerts are tuned for a low false-alarm rate; trial on your own history recommended.

Open in the app

Pipe network

We watch: Which mains to renew first (the order is tested; a chance of breaking is not), surge, closed valves, pressure-reducing valves.

21checks working

REAL

Real data from City of Topeka: top 10 % of pipes hold 61.7 % of 478 breaks vs 52.3 % by material alone (latest test).

Open in the app

Pump station

We watch: Vibration, bearings, curve, cavitation, short cycling.

54checks working

OWN SIMULATED

Passed our own simulated tests and held-out tests on simulated records; no real-plant pass yet.

Open in the app

Reservoir and tank

We watch: Level balance, overflow, leakage, chlorine decay.

4checks working

OWN SIMULATED

Tank and chlorine checks pass on our own data.

Buildings and chillers

Air handler

We watch: Dampers, valves, filters, mixed air, stuck or spiking sensors.

8checks working

REAL

Narrow pass on real Korean office air handlers: injected sensor bias found, nothing false (9 of 19 stretches judged).

Open in the app

VAV box

We watch: Stuck damper and airflow bias against the box's own normal level.

2new checks(new, tested on real data, not yet in the main count)

REAL

Real evening set (Figshare 27948192): 18 of 18 stuck dampers, 7 of 8 airflow bias, 1 false alarm in 234.

Open in the app

Fan coil

We watch: Leaking valves, filters, dampers, fan loss, zone sensor bias.

9checks working

OUTSIDE SIMULATOR

LBNL fan-coil open files: 4 of 4 faults, 0 false calls (easy by construction).

Open in the app

Chiller

We watch: Fouling, undercharge, flow loss, staging, sensor bias.

26checks working

REAL OUTSIDE SIMULATOR

Real data from the FrostByte rig: all severe fault groups named right on rig data it had not seen, no healthy period alarmed. FrostByte (TH Wildau), CC BY-NC 4.0: shown one-to-one only; do not copy or forward. Outside simulator (LBNL plant): 9 of 10 aimed fault pairs found in each of two later tests, no false calls.
