Where does InstruSelect get its flow meter data?

From published manufacturer data — datasheets, application notes and technical documentation — combined with established engineering selection principles. InstruSelect does not invent or approximate specifications; uncertain figures are flagged rather than guessed.

How does InstruSelect decide which meters fit my process?

It screens your inputs — fluid type, flow range, pressure, temperature, pipe size, accuracy, conductivity, viscosity, density, solids, entrained gas, material compatibility, installation limits and application type — against each meter’s published specification, then ranks the suitable options with the reasoning shown.

Data & Validation

InstruSelect is a vendor-agnostic flow meter selection platform that helps engineers compare options across manufacturers based on published specs. This page explains exactly where that data comes from, how recommendations are screened, and — just as importantly — what InstruSelect does not claim.

Where the data comes from

Every recommendation is built on published manufacturer data: datasheets, application notes and technical documentation, cross-referenced against the manufacturer’s own published figures wherever possible. On top of that sits a layer of established engineering selection principles — fluid dynamics, accuracy classes, turndown limits and installation requirements that apply regardless of brand.

InstruSelect does not invent or approximate technical specifications. Where a figure is uncertain or unpublished, it is flagged rather than guessed. Because manufacturers revise their specifications over time, you should always confirm the exact figures for a chosen model against the manufacturer’s current datasheet.

Is it manufacturer-approved?

No — and it is important to be clear about this. InstruSelect’s recommendations are independent shortlist guidance. They are not endorsed, approved or verified by the manufacturers named, and a recommendation is not an implied endorsement by that manufacturer. InstruSelect sits at the early, cross-manufacturer shortlisting stage of selection — before manufacturer sizing and before final project approval.

How recommendations are screened

Each candidate meter is checked against your process inputs across the following criteria, then scored on how well its published specification fits:

Fluid type & phaseLiquid, gas, steam or multi-phase — the first filter that rules technologies in or out.

Flow range & turndownMinimum and maximum flow, and the ratio between them, against each technology’s usable range.

PressureOperating and design pressure against the meter’s pressure rating and construction.

TemperatureProcess temperature against sensor and electronics limits and material selection.

Pipe sizeNominal diameter against available meter sizes and velocity limits.

Accuracy requirementCustody-transfer vs. process-control accuracy, matched to technology capability.

ConductivityElectrical conductivity threshold (e.g. for electromagnetic suitability).

ViscosityFluid viscosity against technology tolerance (Coriolis vs. turbine vs. vortex).

DensityUsed in mass/volumetric considerations and sizing checks.

Solids & entrained gasSlurry, particulate and two-phase content that degrade certain technologies.

Material compatibilityWetted-material compatibility with corrosive or abrasive fluids.

Installation limitsStraight pipe-run requirements, orientation, and hazardous-area (ATEX/IECEx) constraints.

Application typeCustody transfer, process control, utility monitoring or allocation — which shifts priorities.

What the result labels mean

Each recommended meter carries one or more status labels so you can see, at a glance, how far that result has been validated:

AI ShortlistedSelected by InstruSelect based on the conditions you entered. Shown on every result.

Datasheet MatchedThe meter’s key parameters match published manufacturer data for the values you entered.

Supplier Review AvailableA supplier can review the shortlist — request a quote from the result to start that conversation.

We deliberately do not show a “Manufacturer Confirmed” label, because there is no manufacturer confirmation process behind these results. If that ever changes through a formal partner process, it will be stated explicitly.

What this means for your workflow

Use InstruSelect to compare flow meter options across manufacturers and reach a defensible shortlist quickly. Then confirm the final selection against the latest manufacturer datasheet, your project specification, and a supplier or manufacturer review. It is an engineering support and shortlisting tool — not a replacement for manufacturer sizing or final approval.
