BALENG-003
Industrial Instrumentation
Europe · 2025
Systematic analysis and correction of flow measurement errors across a fleet of FE-series electromagnetic flow meters. We identified a product-line calibration defect in 300FE units — a systematic 3.91× over-read consistent with a polynomial area term error — and derived trim factors for four customer-site installations ranging from DN100 to DN300. Post-trim RMSE across all units: <1%. All units recovered to within Aqualink's 3–5% DMA acceptance threshold without hardware replacement.
→ Sub-1% RMSE across 4 units after trim
→ Product-line defect identified in 300FE series
→ T-piece installation effects characterised and corrected
→ Copy-paste AQ formulas delivered for direct device upload

BALENG-007
Water Infrastructure
Ireland · 2026
Technical challenge to a DN300 pipe upgrade specification issued by Uisce Éireann (Irish Water) for a 178-house residential development in County Kerry. Using EPANET 2.2 modelling (KILCUMMIN 2 After.net) and EN 805:2025 §4.1.4 / §7.3.4 compliance analysis, we demonstrated that DN300 fails the velocity criterion under all realistic operating conditions (0.114 m/s at peak vs. 0.3 m/s minimum) while DN150 passes both headloss and velocity criteria at €95,000 lower capital cost. We also identified that Uisce Éireann's calculations appear to use C ≈ 130 (appropriate for aged cast iron), whereas the installed PVC pipe warrants C = 150 per published laboratory and field data — materially reducing the calculated headloss.
→ EPANET model validated against field data (C=150 back-calculated)
→ DN300 shown non-compliant under EN 805:2025 §4.1.4 and §7.3.4
→ DN150 confirmed as correct specification at 30× better cost-effectiveness per m of headloss recovered
→ EN 805:2025 first-party licence citations integrated throughout

// about baltar consulting
Baltar Consulting is the engineering practice of Baltar Inc. We engage on technically demanding problems in water infrastructure, process engineering, and industrial instrumentation — the kind of work where the deliverable is a number someone will act on or a document that will be cited in a regulatory submission.
Our projects have included calibration recovery for industrial flow meter fleets with multi-hundred-percent baseline errors; P&ID design packages delivered to ISA-5.1 standard for process facilities; and hydraulic technical appendices that successfully challenged water utility specifications using first-principles EPANET modelling and EN 805:2025 standards analysis.
Every deliverable is calculation-backed, reference-cited, and revision-controlled. We don't produce opinions — we produce defensible engineering analysis.
