Chemical Dosing Flowmeter Control Package

Calculates source-bound chemical dosing control metrics from a deterministic SSC-18 task-owned source pack. The template combines dose mass, product solution volume, required dosing pump flow, 4-20 mA flowmeter scaling, high-alarm current, pump current, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

All source-pack values given for the SSC-18 dosing flowmeter control package
medium:
All source-pack values given for the SSC-18 dosing flowmeter control package
