FCD Technical Information for Engineers, Specifiers & Facilities Professionals
Document Attribution & Disclosure
The technical documents on this page were authored and published by the device manufacturer. Water Flow Innovation LLC distributes the Flow Conditioning Device as an authorized reseller and makes these documents available as a reference resource for engineers, specifiers, and facilities professionals evaluating the FCD. All studies, white papers, and technical specifications reflect the manufacturer’s research and engineering documentation.
🏗️
For MEP Engineers & Specifiers
The Hydraulic Conditioning White Paper, Technical Engineering Spec Sheet, and Installation & Plumbing Code Reference are the primary documents for CSI Division 22 specification work. Use the M&V White Paper to validate savings calculations for sustainability reporting.
🏭
For Plant Engineers & Facilities Directors
The Water Meter Accuracy White Paper and Technical Validation of Entrained Air document explain why water meters over-register and how the FCD corrects it. Start here if your facility manager is asking why the bill is high.
💼
For Procurement & Operations
The FCD Overview Sheet provides a concise summary of the device, its certifications (IAPMO, NSF/ANSI/CAN 61), and specifications for procurement review. The Savings Mechanism document supports capital project justification and ROI documentation.
Technical Document Library
Eight manufacturer-authored technical documents covering engineering specifications, hydraulic science, measurement standards, installation requirements, and water meter accuracy. All documents are available as PDF downloads.
Flow Conditioning in Commercial Water Systems
The primary technical white paper on hydraulic conditioning science — how turbulence, entrained air, and pressure transients cause water meters to over-register, and how flow conditioning corrects each mechanism.
FCD Technical Engineering Specification Sheet
The formal engineering specification for the Flow Conditioning Device — materials, pressure ratings, flow parameters, connection configurations, and compliance certifications. Required for inclusion in construction documents and RFP specifications.
Installation & Plumbing Code Reference
Installation requirements, plumbing code compliance guidance, and placement specifications for the FCD at municipal supply connections. Covers IPC, UPC, and local amendment considerations for licensed plumbing contractors and MEP engineers specifying the device.
The Standard of Proof: Measurement & Verification in Commercial Water Conservation
A rigorous M&V framework for documenting, validating, and reporting FCD water savings — developed to meet the standards required for sustainability reporting, LEED documentation, and corporate ESG water reduction commitments.
How the FCD Delivers Water & Sewer Bill Savings
A clear, accessible explanation of the FCD savings mechanism — written for facilities managers, operations directors, and procurement teams who need to understand the science without engineering depth. Supports internal justification and capital approval processes.
Technical Validation: Entrained Air and Gas in Fluid Metering Systems
A peer-reviewed technical validation study documenting how entrained air and dissolved gas in municipal water supply lines cause positive metering error — the primary mechanism by which commercial customers are overbilled for water not delivered.
Water Meter Accuracy Acceptance Windows and Municipal Billing
Documents the AWWA and NIST meter accuracy standards that allow municipalities to bill customers based on meters that are operating within “acceptable” error ranges — and how those acceptance windows result in systematic over-billing at the customer’s expense.
FCD Overview — One-Page Reference
A concise one-page summary of the Flow Conditioning Device — certifications, specifications, key benefits, and contact information. Designed for distribution to facility managers, property owners, and operations teams as a quick-reference document.
Intrinsic Fail-Open Architecture
A formal engineering paper on the FCD’s failure behavior — architecture, FMEA, fault tree analysis, risk assessment, and a sixteen-year field record. Written for consulting engineers, facility engineers, EPC reviewers, insurers, and procurement teams evaluating whether the FCD introduces any supply-interruption risk.
Need a Sizing Confirmation Before Specifying?
The FCD requires sizing confirmation based on five parameters — pipe size, meter size, PRV configuration, backflow preventer type, and static supply pressure. Submit your project parameters and WFI will confirm the correct model within one business day.
