Compact piston prover

Small-volume (compact) piston prover on a skid: honed flow tube between bolted inlet and outlet housings, nitrogen spring plenum with charge panel, optical switch housing with detector blocks, duplicate flow-tube TTs and housing PTs, a hydraulic piston-return pack, and a motor-operated 4-way diverter valve with seal-check bleed that sends meter flow through the prover in either direction. Prover controller, cable tray, supports and shackled padeyes.

Installation

Copies packages/compact-prover.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 { CompactProver } from './components/deck-twin/packages/compact-prover'

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

Props

P&ID

A horizontal flow tube with a piston (displacer) drawn inside and two detector switches on top marking the calibrated volume, connected by a prover loop with valves to the metering skid; often just a box labelled "prover".

Piston in a tube with detector marks = compact prover; a long U-shaped pipe loop with spheres is a conventional ball prover. ISA codes here: ZS = detector.

For agents

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

Or fetch /r/compact-prover.json, or copy a ready-made instruction:

Add the Deck Twin "Compact piston prover" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add compact-prover` (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 compact-prover` for its props, ranges and ports. Render <CompactProver /> 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.
