Predictika · Electromagnetic flowmeter orders

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

An AI sales agent prepares an order for a Proline Promag P 500 electromagnetic flowmeter: sensor size and liner, process connection, transmitter electronics, outputs and inputs, housing and cable. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published ordering and application limits and returns a verdict, every reason and the figures it computed.

Scope: Proline Promag P 500 (remote version) flowmeter orders: sensor diameter and liner, process connection, transmitter electronics, outputs and inputs, ambient and medium limits. See everything this validator covers

This validator models orders for the Proline Promag P 500 electromagnetic flowmeter, not just the scenarios shown below.

  • Sensor and liner — nominal diameters DN 15 to 600; a PFA or high-temperature PFA liner is offered for DN 25 to 200 only, PTFE for all sizes; each liner has a medium temperature range (PFA −20 to 150 °C, high-temperature PFA to 180 °C, PTFE −40 to 130 °C); the medium needs at least 5 µS/cm.
  • Process connection — EN 1092-1, ASME B16.5 and JIS flanges; there is no ASME Class 150 flange for DN 32, 65 or 125; EN flange pressure is checked against the nominal rating for the diameter (PN 40 up to DN 50, PN 16 up to DN 150, PN 10 above); carbon steel flanges limit the sensor ambient temperature to −10 °C, stainless steel to −40 °C.
  • Transmitter, outputs and inputs — the digital (sensor-side electronics) and standard transmitters and their housings; which options are offered for outputs and inputs 2, 3 and 4 given output 1 (including Ex i and fieldbus versions), the double pulse pairing, output 4 only on the digital transmitter, the maximum connecting cable length, the −40 °C transmitter ambient limit and the −50 °C option, and display readability below −20 °C.

Any Promag P 500 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Endress+Hauser does not publish list prices, so this validator produces no price build-up or line-item quote), the full order code and Product Configurator, hazardous-area approvals, electrode materials and chemical compatibility with the medium, pressure derating with temperature, ASME and JIS pressure ratings, vacuum limits, AS flanges, the cable length versus conductivity chart, application packages, accessories, and other Proline families.

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
Outputs and inputs that are not offered togetherOnly with workarounds
Which options exist for outputs 2, 3 and 4 depends on output 1, and the double pulse pairing and the output 4 limit add more; that is a table of excluded combinations across four choices that has to be built and kept in step by hand.		All four choices arrive in one request and are checked against the published combinations, whichever order they were made in.
A liner that cannot take the medium temperature or the line sizeOnly with care
Each liner has its own temperature range and size range; a rule per liner works, but every new liner or limit is another rule to maintain.		Liner, diameter and the medium's temperature range are in one request and are compared on every call.
Ambient limits that depend on a different choiceOnly with workarounds
The sensor's lowest ambient temperature depends on the flange material, and the transmitter's on an option, while the two sit in different places; each needs its own cross-line rule.		Both locations are separate fields in the request; each is compared with the limit that follows from the choices actually made.
Cable length that depends on the electronicsOnly with care
The allowed cable is 300 m for one transmitter and 200 m for the other, so the rule needs the electronics choice and the length together.		The electronics and the length travel together and the limit is computed on every call.
Stated temperature rating that must match the linerOnly with care
A stated figure is a free-entry field; a rule can compare it with the liner's rating, but someone has to write and maintain that comparison.		The stated figure travels with the order and is compared with the computed rating on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or 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.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

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 a Proline Promag P 500 electromagnetic flowmeter: sensor size and liner, process connection, transmitter electronics, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published ordering and application limits 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 a Proline Promag P 500 with a DN 100 sensor, PTFE liner and EN 1092-1 carbon steel flanges. The liquid is 800 µS/cm, runs from -10 to 90 °C at 10 bar; the sensor sees down to -5 °C and the transmitter down to -10 °C. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The option chosen for output/input 2 is not available with the option chosen for output/input 1. The option chosen for output/input 4 is not available with the option chosen for output/input 1. Output/input 4 is available only for the Proline 500 - digital transmitter. The other one is on screen.
    6. 
      
  6. The validator returned four 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 outputs and inputs that are not offered together, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the transmitter to Proline 500 - digital, the output/input 2 to 4-20 mA Ex i passive, the output/input 3 to 4-20 mA Ex i passive and the output/input 4 to not assigned.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Four problems caught in one call, fixed in one pass, 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.
    14.
