Multimodal Flow Measurement & Sensor Diagnostics Agent with Google ADK

Accurate flow rate measurement in process plants requires combining calibration datasheets, piping diagrams, and ultrasonic sensor signals. Develop a multimodal industrial agent using Google ADK to analyze flow meter imagery, detect installation errors, and compute inline calibration offsets.

Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Build a multimodal process engineering agent using Google ADK and Gemini models to evaluate visual flow meter installations and diagnostic data.

Delivery guide

How work is evaluated

Evaluation

Evaluates agent ability to detect insufficient straight pipe runs upstream of a flow meter from an engineering diagram input.

Datasets

Challenge datasets

Public datasets, plus the private datasets you have access to.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

installation_validation_check

Ensures undersized straight runs are flagged as invalid.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

error_estimation_accuracy

Accuracy of estimated percentage error compared to standard fluid dynamics equations. • target: 0.95 • range: 0.8-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Configure Google Agent Development Kit (ADK) with Gemini multimodal tools

  • Process visual P&ID (Piping & Instrumentation Diagram) images and installation photos

  • Compute Reynolds number and straight pipe run requirements upstream/downstream

  • Generate automated calibration correction formulas for differential pressure meters
