Product Overview
The Vision BV3000 is the largest meter in the Vision line — a 3/4 in compact turbine covering 1.32–17.17 gpm for cooling and process loops the smaller Vision meters cannot reach. A bladed rotor drives a Hall-effect frequency output (NPN open-collector, 5–24 VDC) scaled by a fixed K-factor, read and scaled by a PLC, batch controller or rate/total display. It holds ±3% accuracy to 362.5 psi and −4 to 212°F in a clear, BPA-free Trogamid body, and mounts in any orientation with no straight run — the right Vision meter for industrial cooling, solar, process and larger dosing duties.
Key Features & Benefits
- The largest flow in the line — a 3/4 in port carries 1.32–17.17 gpm — the BV3000 reaches cooling and process duties out of range for the 1/4 in and 3/8 in Vision bodies. The line’s highest capacity.
- Compact and orientation-free — the rotor mass is tiny, so the meter installs vertically, horizontally or at any angle and needs no upstream straight run — it fits tight skids and machine builds. Drops into the pipework you have.
- Clean Hall-effect pulse to your readout — an NPN open-collector frequency, scaled by a fixed K-factor, feeds a PLC, flow computer, batch controller or rate/total display. One signal, scaled wherever it lands.
- Repeatable batching at higher flow — ±3% of reading and under 0.5% repeatability hold for the larger cooling, dosing and process duties. Consistent totals on a bigger loop.

Common Applications
- Industrial cooling systems and chilled-water loops at higher flow
- Process and washing-plant water at 3/4 in line size
- Solar thermal loops and heat-transfer fluid circulation
- Larger dosing and water-treatment / filter-monitoring duties
- OEM machine builds needing the top of the Vision flow range
The BV3000 is the largest Vision turbine. For 3/8 in mid-range flow use the BV2000; for micro-flow dosing the BV1000. For a thick or variable-viscosity fluid, or for high-flow water sub-metering, a different measurement principle fits better — an oval-gear positive-displacement or an electromagnetic / ultrasonic meter from the Badger Meter flow family.
Design & Selection Considerations
- Match the meter to a thin, clean fluid — Vision is a low-viscosity turbine, rated to about 16 cSt, and like any turbine its calibration shifts as the fluid thickens. Water, coolant, beverage, light oil and fuel suit it; a thick or variable-viscosity fluid is the wrong job for it — an oval-gear positive-displacement meter holds accuracy there. A 20–40 µm filter upstream keeps grit off the rotor and bearings. Use the input form to tell us the fluid and its viscosity and we’ll confirm Vision fits before sizing.
- It is pulse-output only — plan the readout — every Vision puts out an NPN open-collector Hall-effect frequency (5–24 VDC, a pull-up resistor required) scaled by a fixed K-factor — there is no 4–20 mA or Modbus card on the meter. A PLC, flow computer, batch controller or rate/total display reads and scales the pulse; a local rate-and-total readout or a scaled analog output lives in that downstream counter. Use the input form to tell us how the signal has to land and we’ll size the meter and the readout together.
- Body material follows the fluid and the approval — Trogamid is the clear, BPA-free polymer body certified to NSF/ANSI/CAN 61 & 372 (on the BV1000 and BV2000) for potable water, food, beverage and medical fluids — and being clear it lets you see the rotor turn; Grilamid is the tougher opaque BV1000-only body; and lead-free brass is the rigid metal-port BV2000 option for food and beverage. Use the input form to tell us the fluid and whether a drinking-water approval is required and we’ll specify the body.
- Size to the flow, mount it anywhere — response is fast and resolution is high (up to 83,000 pulses per gallon) because the rotor mass is tiny, and the meter needs no upstream straight run and mounts in any orientation, even in tight pipework. Pick the model and K-factor build by your normal and minimum flow, not the line size: the BV1000 for micro-flow dosing, the BV2000 across six mid-range builds, the BV3000 for cooling and process loops. Use the input form to send the normal and minimum flow and the port size and we’ll point you to the model and K-factor.
To spec the right BV3000 turbine meter:
Use the input form to tell us the fluid, the normal and minimum flow, the port size and the body (and whether a drinking-water approval is required), and we’ll confirm the model, K-factor build and connection — and the downstream readout the pulse output lands in.
