An AI sales agent's flowmeter order, checked before it goes out

An AI sales agent prepares an order for KROHNE OPTIFLUX 2000 electromagnetic flowmeters: nominal size, signal converter, liner, flange standard, process temperature and pressure, and options such as legal metrology, IP68 and the virtual reference. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the limits in the public OPTIFLUX 2000 datasheet and returns a verdict, every reason and the figures it computed.

Scope: KROHNE OPTIFLUX 2000 flowmeter orders: nominal size, signal converter, liner, flange standard, temperature, pressure, legal metrology, IP68, grounding, conductivity, velocity and accuracy. See everything this validator covers

This validator models orders for the OPTIFLUX 2000 sensor built from the public datasheet limits below, not just the scenarios shown.

  • Size and converter — the IFC 050 and IFC 100 converters cover DN25 to DN1200 and the IFC 300 covers DN25 to DN3000; the converter also sets the accuracy (0.5, 0.3 and 0.2 percent of the measured value, plus 1 mm/s, or 0.3 percent plus 2 mm/s above DN1600 on the IFC 300).
  • Liner and temperature — polypropylene up to DN150 (to 90 degrees C), hard rubber from DN200 (to 80 degrees C), and the optional polyolefin liner for DN200 to DN1000 (to 80 degrees C); process temperature from -5 degrees C.
  • Flanges and pressure — EN 1092-1 pressure ratings by size (PN40 down to PN2.5), AWWA ratings for the sizes it covers, and the size limits of ASME B16.5 and JIS flanges; the operating pressure is compared with the EN and AWWA ratings and with the rating the agent states.
  • Options — legal metrology (OIML R49, MID) only with the IFC 300; IP68 only for the remote design with a stainless steel connection box; the virtual reference (no grounding rings) only with the IFC 300, at 200 microsiemens per cm or more and with a cable of 50 m or less.
  • Medium and flow — a conductivity of at least 5 microsiemens per cm (20 for demineralised water) and a flow velocity up to 12 m/s; vacuum service goes to a person for approval.

Any OPTIFLUX 2000 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none were used, so this validator produces no price build-up or line-item quote), other KROHNE meters, the vacuum-load table, pressure ratings for ASME and JIS flanges, ambient temperature limits, electrode and ring materials beyond the virtual reference, and the optional hard rubber liner for DN25 to DN150 that only one datasheet copy lists. Nominal sizes are limited to those named in the datasheet tables (DN25, 50, 65, 80, 100, 150, 200, 700, 1000, 1200, 1600, 1800, 2000, 2200 and 3000).

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A liner that depends on the nominal size, with a temperature limit that depends on the linerOnly with care
The liner follows from the size and the option chosen, and the temperature limit follows from the liner, so each link needs its own rule and a calculated field.		The size, liner option and temperature are in one request and the liner limit is derived and checked on every call.
A signal converter that limits the size range and unlocks options such as legal metrology and the virtual referenceOnly with workarounds
One choice constrains several others, so each pairing needs a rule and the set grows with every option.		The converter is checked against size, legal metrology, grounding, conductivity and cable length in one pass.
A flange rating that depends on the size and the flange standard, compared with the operating pressureOnly with care
The rating is a lookup by size and standard, and a separate validation rule compares it with the pressure.		The rating is computed from the size and standard and compared with both the pressure and the rating the agent stated.
An accuracy that follows from the converter and the size, compared with what the agent statedOnly with workarounds
These are formulas rather than choices, so they need calculated fields and a rule that compares them with the stated figure.		The accuracy is computed from the order and compared with the agent's stated figure.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for KROHNE OPTIFLUX 2000 electromagnetic flowmeters: nominal size, signal converter, liner, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the limits in the public OPTIFLUX 2000 datasheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 12 OPTIFLUX 2000 flowmeters, DN150, with the IFC 100 signal converter in the compact design, the optional polyolefin liner and EN 1092-1 flanges. The quote states an accuracy of 0.30 percent of the measured value and a flange rating of 16 bar. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The optional polyolefin liner is offered for DN200 to DN1000 only; the order is DN150. A process temperature of 85 degrees C is outside the -5 to +80 degrees C range of the liner that comes with this size and liner option. Legal metrology approval (OIML R49, MID) is only available in combination with the IFC 300 signal converter.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a signal converter that limits the size range and unlocks options such as legal metrology and the virtual reference, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the signal converter to IFC 300 and the stated accuracy as to 0.20.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The optional polyolefin liner is offered for DN200 to DN1000 only; the order is DN150. A process temperature of 85 degrees C is outside the -5 to +80 degrees C range of the liner that comes with this size and liner option.
    12. 
      
  12. One finding cleared. Still blocking: polyolefin liner not available at this size and process temperature outside the liner range.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the liner to standard for the size.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
