Product Overview
The Vision BV2000 is the mid-range workhorse of the Vision line — a 3/8 in compact turbine covering 0.13–9.2 gpm across six K-factor builds, so the meter is matched to your specific flow window rather than one wide span. A bladed rotor drives a Hall-effect frequency output (NPN open-collector, 5–24 VDC) that a PLC, batch controller or rate/total display reads and scales. It holds ±3% accuracy to 362.5 psi and −4 to 212°F, mounts in any orientation with no straight run, and comes as a clear NSF/ANSI/CAN 61 & 372 Trogamid body or a lead-free brass body for food and beverage — the right meter for dispensing, dosing and OEM integration at mid-range flow.
Two bodies for two duties
The BV2000 is offered in two bodies. Both are the same 3/8 in mid-range turbine (same Hall-effect output and ratings) — the body material and the certified flow span differ.
Trogamid (clear)
NSF-certified polymer
- Clear, BPA-free body — you can see the rotor turn
- NSF/ANSI/CAN 61 & 372 for potable, food and medical fluids
- Full 0.13–9.2 gpm span across six K-factor builds; NPT or parallel-G threads
Brass (CuZn38)
rigid lead-free metal port
- Lead-free brass (CuZn38) body for food and beverage duties
- Rigid metallic ports where a metal connection is preferred
- 0.5–6.6 gpm across two builds; NPT or parallel-G threads
Both are the BV2000 — 3/8 in, NPN Hall-effect output, ±3% accuracy, 362.5 psi, −4 to 212°F. The body material and the certified flow span differ.
Key Features & Benefits
- Six builds, matched to your flow window — the BV2000 ships in six K-factor ranges (050 through 350) so the meter is sized to your specific flow band instead of one wide span — tighter resolution where you actually run. Pick the build that runs mid-band at your normal flow.
- Clear or metal — your choice of body — the same meter comes as a clear NSF-certified Trogamid body or a rigid lead-free brass body for food and beverage where a metal port is preferred (see Variants). The body the spec calls for, same measurement underneath.
- Mounts anywhere, no straight run — fast response and any-orientation mounting with no upstream straight pipe required — it drops into tight machine pipework. Fits the build, not the other way round.
- Repeatable enough to batch on — ±3% of reading with under 0.5% repeatability is tight enough for the repeatable batching and dispensing these meters are built for. Consistent shot-to-shot.
Specifications

- Flow range
- 0.13–9.2 gpm (0.5–35 lpm) on Trogamid, spread across six K-factor builds (the 050 through 350 ranges — see the table); the brass body covers 0.5–6.6 gpm.
- K-factor (resolution)
- 26,100 down to 2,840 pulses per gallon by range (Trogamid) — each build matched to its flow window rather than one wide span.
- Accuracy
- ±3% of reading.

- Line size / ports
- 3/8 in — NPT or parallel-G (BSPP) threads, on both the clear Trogamid and the lead-free brass body.
- Body materials
- Trogamid (clear, BPA-free, NSF/ANSI/CAN 61 & 372 certified) or lead-free brass (CuZn38) — see Variants.

Common Applications
- Dispensing and dosing systems — the mid-range workhorse for OEM machine builds
- Food & beverage — coffee, vending, bakery and steam-cooking equipment (clear or brass body)
- Chemical and pharma dosing and bottling plants
- Cooling systems, washing plants and water-treatment / filter-monitoring loops
- Fuel-consumption measurement and light-oil metering
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 BV2000 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.
