Product Overview
The Vision BV1000 is the micro-flow turbine in the Vision line — 0.026–0.65 gpm through a 1/4 in port, with the highest resolution Vision offers (up to 83,270 pulses per gallon). A small bladed rotor drives a Hall-effect frequency output (NPN open-collector, 5–24 VDC) scaled by a fixed K-factor, so a PLC, batch controller or rate/total display reads flow and total directly. It mounts in any orientation with no straight run, holds ±3% accuracy to 362.5 psi and −4 to 212°F, and is the only Vision model that can be ordered with a 6 mm push-fit end. The body comes clear NSF-certified Trogamid or rugged fiberglass-reinforced Grilamid, with the connection — threaded or push-fit — chosen separately. The right meter for the smallest dispensing, dosing and OEM duties.
Two body materials
The BV1000 is offered in two body materials. Both are the same micro-flow turbine (0.026–0.65 gpm, same Hall-effect output and ratings) — the housing material differs, and the connection (1/4 in NPT, parallel-G, or 6 mm push-fit) is selected separately at order. Push-fit is offered only on the BV1000.
- Clear, BPA-free body — you can see the rotor turn
- NSF/ANSI/CAN 61 & 372 certified for potable, food and medical fluids
- The choice where a drinking-water approval is required
- Fiberglass-reinforced for a tougher OEM build
- Opaque — the choice where ruggedness beats visibility
- Not carried under the NSF/ANSI/CAN 61 & 372 certification
Key Features & Benefits
- Highest resolution in the line — the finest K-factor Vision offers makes each pulse a tiny, repeatable volume — the right meter when a dose has to be small and exact. When a small dose has to be counted accurately.
- The only Vision with a push-fit option — the BV1000 is the one model in the line offered with a 6 mm push-fit connection for fast tool-free plumbing into OEM machine builds, alongside the standard 1/4 in NPT and parallel-G threads. Drop-in integration on a production line.
- Mounts anywhere, no straight run — the tiny rotor mass gives fast response and lets the meter read in any orientation in tight pipework, with no upstream straight pipe required. Fits the machine, not the other way round.
- Certified for potable and food contact — the clear Trogamid body is BPA-free and carries the drinking-water certification, so it suits potable, food, beverage and medical fluids. Spec-clean for consumable-contact service.
Specifications

Common Applications
- Micro-dosing and the smallest dispensing duties in OEM machine builds
- Coffee, vending and beverage machines — precise small-volume shots
- Medical and dental — sterilizers, dental water jets, dialysis micro-fluid metering
- Chemical and pharma dosing where the dose is a fraction of a gallon per minute
- Laser / electronics cooling and solar loops at low flow
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 BV1000 micro-flow 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.
