UFM CoolPoint CX8 Vortex Flowmeter

1-inch vortex-shedding flowmeter for continuous or batch water add on concrete trucks — max 50 GPM (190 LPM), ±1½% full-scale accuracy, 10:1 turndown, and pulse or 4–20 mA rate output with optional 3-digit LED.

Key advantages

Concrete-truck duty — OEM positions CX8 for water-add monitoring in batch (total) or continuous-mix rate modes.
No moving parts — Vortex shedding with brass/nylon flow body and PEEK sensors; over-range to 125% without damage per OEM sheet.
±1½% FS / 10:1 — Accuracy ±1½% full scale; repeatability ±0.25% of indicated; turndown 10:1.
Flexible outputs — Pulse or 4–20 mA rate; 3-digit LED display options; GPM or LPM engineering units.
Rugged enclosure — IP65 / Type 4X; 10–30 VDC @ 80 mA (3-wire); female NPT; max 200 PSI (13.6 bar).

Typical applications

Water-add metering on ready-mix / concrete trucks.
Continuous-mix rate display and pulse totalizing.
Low-viscosity water service compatible with brass, nylon, Viton, and PEEK wetted parts.
OEM skids needing a compact 1 in vortex transmitter.

Selection guide

End connection — Brass with nylon endcaps (M8) vs brass with nylon hose barbs (M7) per OEM model code.
Output / display — Pulse with total display (D3), 4–20 mA with rate display (D1), or no-display pulse / 4–20 mA variants.
Cabling — 5-pin connector (C1) vs weather-pack cable add-on (C7).
Flow orientation — N1–N4 face/pin orientations for up / left / right / down flow.

Common mistakes

Ignoring straight-run needs — OEM calls for 10 diameters upstream and 5 downstream for published accuracy.
Running without enough backpressure — typical 5 PSI midrange / 10 PSI at high flows.
Ordering for fluids outside brass/nylon/Viton/PEEK compatibility.
Confusing CX8 concrete brass body with the polysulfone CX plastic series accuracy statements (±1% FS on that sheet).

FAQ

Q: Is CX8 for concrete trucks only? A: OEM markets it for continuous or batch water add on concrete trucks; materials suit water and compatible low-viscosity fluids.

Q: Pulse or 4–20 mA? A: Both are available — pick the output/display code when ordering.

Q: What should I send for a quote? A: Model-code options (body, output, cable, orientation), quantity, ship-to.
