What Orrery builds, and what it is for

Five instrument families, each with the measurement it makes, the service level it belongs to and its lead time. The assistant specifies from this list, never from memory.

Code	What it is	What it covers	Plan	Turnaround
`ORR-COR`	Coriolis mass flow	Direct mass flow and density on liquids and slurries, ±0.1% of rate, DN15 to DN150, wetted parts in 316L or a nickel alloy for caustics and acids.	Assured	Standard builds ship in 4 weeks; alloy wetted parts 8 weeks
`ORR-MAG`	Electromagnetic flow	Volumetric flow on conductive liquids — water, effluent, pulp — DN25 to DN600, with a liner chosen for the medium rather than the price list.	Standard	3 weeks to DN300; 6 weeks above
`ORR-DPC`	Differential pressure	The original Orrery cell: differential, gauge and absolute pressure to 400 bar, with a turndown that holds accuracy at the bottom of the range.	Standard	2 weeks; 5 days on the nine most-ordered configurations
`ORR-TMP`	Temperature assemblies	Resistance thermometers and thermocouples built as a complete assembly — sensor, thermowell, transmitter — sized against the flow that will bend it.	Standard	3 weeks including a wake-frequency calculation
`ORR-CAL`	Calibration and recertification	Accredited recalibration of any Orrery instrument, on site or at Rotterdam, with the certificate and the as-found data before adjustment.	Assured and Resident	5 working days in-house; site visits booked within 10

The assistant reads this same table through its list_services tool, so what it tells you and what this page says cannot drift apart.
