Vibrating fork level switch

Vibrating fork point level switch for side mounting: flanged process connection (port process, facing -X, origin on the face), extension tube and two flat tines set side by side so the gap drains vertically, a finned thermal neck and a compact housing with status LEDs behind a window and two cable entries underneath. Fork length from the flange face is a prop.

Installation

Copies instruments/level-switch.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 { LevelSwitch } from './components/deck-twin/instruments/level-switch'

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

Props

P&ID

Field bubble with LS plus H / HH / L / LL (LSH, LSHH, LSLL) on a side connection of a vessel or bridle at the trip height. In a SIS it is often drawn with a diamond or hexagon tag for the logic it feeds.

ISA LSHISA LSHHISA LSLISA LSLLISA LSISA 5.1 (field-mounted instrument bubble)

S = switch, so the bubble has no transmitter letter T. Trip levels are written beside it in mm or %. Vibrating fork, float and displacer switches all use the same bubble.

Emerson (Rosemount). 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/level-switch.json, or copy a ready-made instruction:

Add the Deck Twin "Vibrating fork level switch" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add level-switch` (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 level-switch` for its props, ranges and ports. Render <LevelSwitch /> 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.
