Key parameters
PPS-bodied micro-flow rotor sensor for clean liquids with two range families (0.11…2.6 lpm or 1.13…12.11 lpm) and open-collector frequency output.
Key advantages
- Micro-flow coverage — 0.11…12.11 lpm (0.03…3.2 U.S. gpm) across low- and high-flow codes.
- Opaque or transparent liquids — single moving part; low pressure drop.
- Simple ¼ in. connections — NPT or ISO 7/1-R¼ male threads for tubing or rigid pipe.
- Open-collector output — 5…24 VDC powered; 7.6 m cable standard.
Typical applications
- Coolant flow, dosing, and batch dispensing of clean process liquids.
- Compact skids where a full insertion paddlewheel will not fit.
- Not recommended for strong oxidizers (OEM note).
Selection guide
- Ranges — -11/-12: 0.11…2.6 lpm (0.03…0.7 gpm); -21/-22: 1.13…12.11 lpm (0.3…3.2 gpm).
- Accuracy — Linearity ±1.2% of full range; repeatability ±0.5% of full range.
- Connections — ¼ in. NPT male or ISO 7/1-R¼ male.
- Wetted materials — 40% glass-filled PPS body/cover; natural unfilled PEEK rotor; FKM cover O-ring.
- Electrical — 5…24 VDC ±10%, 10 mA max; open-collector sinking, 20 mA max; cable to 300 m.
- Pressure / temp — 0…80 °C @ 5.5 bar max (32…176 °F @ 80 psi max).
- Notes — Datasheet states not available in EU; confirm ship-to eligibility.
Common mistakes
- Picking the wrong range code (low vs high flow) for the dosing pump window.
- Using with strong oxidizers — OEM advises against.
- Expecting self-powered operation — 2000 needs 5…24 VDC.

When to RFQ / what to tell us
- Target flow (lpm/gpm) and fluid chemistry (confirm not strong oxidizer).
- NPT vs ISO thread; cable length needs.
- Host input type; T/P; quantity; ship-to (EU restriction note).

FAQ
Q: Which range code do I need? A: Low-flow -11/-12 for 0.11…2.6 lpm; high-flow -21/-22 for 1.13…12.11 lpm. State your min/max flow in the RFQ.
Q: Can I ship to the EU? A: Datasheet marks the 2000 as not available in EU — confirm eligibility before ordering.
Q: What should I send for a quote? A: Flow window, fluid, thread standard, host, T/P, quantity, ship-to. Compatible with systems using GF Signet 2000 if you need a drop-in check — we do not claim authorized-dealer status.
