Small server room on a precision unit. Honestly this is here so I know how much headroom is left in the hottest week of the year.

Dewatering the pit. If this stops, work stops, so it gets watched properly rather than checked on.

Frozen container, minus eighteen the whole way. The log is the only thing that survives the journey.

Sat beside a busy road. Mornings are worse than I expected. Still air holds everything in until the sun gets up.

Spindle load and utilisation. Mainly useful when quoting.

Walk-in behind the kitchen. Door openings turn out to be most of the load, which surprised me.

Thirty seven degrees, tight tolerance. A short excursion overnight invalidates a week of work and you would never know.

Clean baseline on campus. We hold the roadside numbers up against this one.

Air handler on the third floor. Half of this is settling arguments about whether it is actually running.

District meter. Night flow is the number that matters. Whatever is still moving at three in the morning is leaking.

One multi-deck on the chilled aisle. I am trying to work out whether the shrinkage is the case or the staff.

Monitoring at the board. We had equipment failing and nobody could say why. Turned out to be sags, not the equipment.

Feed pump on the boiler. It threw a bearing in March and took the boiler down with it. Now it is watched.

Incoming supply for the whole building. Tenants ask what happened. Now I can tell them.

Cycle counts, utilisation, and every short stop. Quoted capacity and actual capacity have never been the same number.

LPG in a hotel kitchen. Reads zero nearly always. That suits me fine.

Frost watch through the season. One night is all it takes.

Carbon monoxide in the underground car park. The fans used to run on a timer whether anyone needed them or not.

A commercial zone where the pipework is sound and the loss is still large. Water that reaches a customer and is never billed follows the demand curve instead of running all night, which is why two zones can lose the same share and need entirely different work.

22 kW drive on line two. The vibration trend is the entire reason it is monitored.

One residential zone of a distribution network, metered on its single inlet, with the volume billed inside the zone alongside it. The gap between the two is non-revenue water, and splitting a network into zones is what turns one town-wide loss figure into somewhere to send a crew.

Cut flowers under glass. Temperature, humidity, CO2 and vent position. One bad afternoon costs a shipment.

Main cold store, product for export. Since we started logging door time the arguments stopped.
