H2Flow FlowVis FVJ‑R Retrofit Flow Meter Kit

The H2Flow FlowVis FVJ‑R is a precision retrofit flow meter kit designed to fit existing 2″ to 2½″ check‑valve / plumbing configurations (particularly popular in Jandy valve systems). It combines high accuracy flow measurement with a compact installation footprint and minimal straight‑pipe requirements.

Key Features:

• Retrofit kit for 2″‑2½″ valves (especially Jandy 2‑way / check‑valve bodies)
• High accuracy (greater than ≈97% across model range) for measuring GPM flow rates in pool/plumbing systems
• Installation flexibility — can be mounted horizontally, vertically or even upside‑down; minimal straight‑run plumbing required
• Integrated check‑valve function in many models simplifies plumbing and ensures correct flow direction
• Manufactured in USA with durable CPVC/ABS housings and clear sight‑scale for easy visual flow readings

Technical Specifications:

• Model / SKU: FVJ‑R
• Suitable Pipe Size: 2″ to 2½″ plumbing / check‑valve bodies
• Flow Range Example: ~10 to 110 GPM in typical 2‑2½″ variant
• Maximum Working Pressure: ~50 psi
• Operating Temperature Range: ~32 °F to ~140 °F
• Certification: NSF 50 rated (for many models in FlowVis line)

Installation & Maintenance Tip: Shut off your pump and relieve system pressure before installing. Remove the old check‑valve body or insert the FlowVis kit into the existing body. Ensure direction of flow arrow aligns with pump discharge direction. Tighten fittings according to manufacturer specs. After startup, visually check flow scale for expected rate (refer to pump curve or plumbing chart). Periodically inspect the clear housing for debris buildup and keep the flow scale lens clean for accurate readings.
