Paste the customer’s email or data sheet — process, pressure, temperature, area classification, signal — and the engine picks the wetted materials, housing, connection and certificates, checks them against the process and the area, and prices the instrument with Good / Better / Best. Every number comes from the rules, never from a guess.
Instrumentation and controls — wetted materials, hazardous-area protection and safety integrity checked before pricing.
Pressure and DP transmitters, temperature assemblies (sensor, transmitter, thermowell), radar level, magnetic flowmeters, control valves with digital positioners and pH analyzers — on 4-20 mA HART, FOUNDATION Fieldbus or PROFIBUS PA, one tag or a hundred.
Wetted materials for the process, including sour service to NACE MR0175 / ISO 15156; hazardous-area protection to NEC 500/505 and IEC 60079; valve body rating to ASME B16.34 and seat leakage to FCI 70-2; and safety integrity: SIL loops get IEC 61508-certified devices.
The certificates the order needs (NACE declaration, EN 10204 3.1, calibration) priced as lines, an instrument data sheet per tag, and the facts the customer must confirm — H2S partial pressure, gas group, valve sizing — stated rather than buried.
Cited rules decide what may be selected for the process and the area — and every price and refusal shows its source.
Free to use — Nteli is paid only when an order is won through it.
An instrument quote built from last year’s ordering guide goes stale the day one of these shifts. The engine doesn’t watch for changes — people teach it: a change comes in with its source, gets replayed against past quotes to show what it touches, is approved by a second person, and ships in a versioned pack. Your quotes cite the rule that priced them.
Sour-service material limits are revised by edition, and the declaration the customer expects follows the edition.
NEC 500/505 and IEC 60079 move on their own cycles, and the approval marking on each device has to match the area it mounts in.
IEC 61508 and 61511 decide which devices may sit in a safety loop, and which certificates come with them.
Makers revise model codes and options every year; a quote built on last year’s code is a reorder waiting to happen.
The engine is a full MCP server — connect it to Claude and your team quotes instruments in plain conversation: paste the data sheet, answer the question card, pick Good / Better / Best. The starter rule pack ships with the line; override it with your own rules, governed and audited — and you're onboarded.
Connect the engine as a custom connector (two steps, shown here), then paste any of these. They were run on the live engine; prices are illustrative until your price book loads.
What you’ll see: “FOUNDATION Fieldbus and SIL 2 can’t go together”: SIL-certified devices (IEC 61508) are offered with a 4-20 mA HART output, and fieldbus versions carry no SIL certificate. Two ways out, each priced: HART for this loop with the SIL certificate, from about $1,785 (the usual choice), or keep the fieldbus if it isn’t a safety loop, from about $1,575.
What you’ll see: An explosionproof Div 1 housing, wetted parts and bolting to NACE MR0175 / ISO 15156 with the declaration and EN 10204 3.1 certificates, and per-device configuration and calibration — about $9,400 for six with the volume break. Better and Best step up to intrinsically safe housings and tantalum diaphragms, and the quote asks you to confirm the H2S partial pressure and gas group.
What you’ll see: A globe valve with a spring-return diaphragm actuator, a Class 600 body rated for the pressure at temperature (ASME B16.34), a lapped metal seat with the Class V leakage test (FCI 70-2) and a digital HART positioner — about $9,600, with the Cv sizing listed for the customer to confirm.
