Ultrasonic flowmeter

Multipath transit-time ultrasonic flowmeter: a forged 3D spoolpiece with weld-neck flanges and 2, 4 or 6 chordal paths at Gauss-Jacobi heights. Each path has a pair of transducer bosses crossing at 45 degrees, enclosed by a stainless transducer shroud (or exposed with individual conduits), a Pm pressure tap with needle valve, an electronics base enclosure and Ex d head on a pedestal, and lifting lugs.

Installation

Copies instruments/ultrasonic-flowmeter.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { UltrasonicFlowmeter } from './components/deck-twin/instruments/ultrasonic-flowmeter'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <UltrasonicFlowmeter />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

Inline spool box with transducer marks on opposite sides and a diagonal acoustic path between them, joined to an FT bubble. Many legends just write "USM" or "UFM" beside a generic FE box.

tag FEISA FEISA FTISA FITISA FQISA 5.1 (flow element + transmitter); ultrasonic element varies by legend

Fiscal gas metering runs (AGA 9) are usually multipath ultrasonic; a clamp-on meter is drawn on the outside of the pipe with no break in the line. Check the technology in the instrument index.

Emerson (Rosemount / Daniel). The geometry is generic and sized from public standards. It is not vendor CAD.

For agents

Machine-readable entry with props, ranges, defaults and ports:

Or fetch /r/ultrasonic-flowmeter.json, or copy a ready-made instruction:

Add the Deck Twin "Ultrasonic flowmeter" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add ultrasonic-flowmeter` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info ultrasonic-flowmeter` for its props, ranges and ports. Render <UltrasonicFlowmeter /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
