BV1000-2000-3000-Series

Supported Applications

Vision Turbine Meters — Models BV1000, BV2000, and BV3000 — are designed for flow measurement of low-viscosity, aggressive, and non-aggressive liquids. They comply with the lead-free provisions of the Safe Drinking Water Act and are certified to NSF/ANSI Standards 61 and 372, making them well suited to food, medical, chemical/pharma, industrial, and automotive applications.

Typical media include demineralized water, alkaline solutions, oils, salad oil, fuel and fuel consumption metering, beverages, water solutions, and coolants. Wetted materials include PA12 Trogamid (NSF/ANSI 61 and 372 certified), Brass CuZn38Al-C, PA12 Ferrite, and Graphite/PTFE, and the meters also carry KTW and W270 approval for drinking water, use FDA approved materials, and meet 21 CFR 175.300.

Operating Conditions & Performance

Across the series, accuracy is ± 3% of reading with repeatability of < 0.50 % under the same operating conditions. The meters handle liquids of up to 16 cSt viscosity and operate over a temperature range of -20...100° C. Operating pressure is 25 bar with a burst pressure of 200 bar. A filter of 20...40 microns is recommended upstream.

Flow ranges scale with meter size, from 0.1...2.5 lpm on the smallest bore up through 0.5...5 lpm, 0.5...7.5 lpm, 1...10 lpm, 1...15 lpm, 1...25 lpm, 2...35 lpm, and 5...65 lpm on the largest. Corresponding K-factors run from 22,000 ppl down to 210 ppl as bore size increases.

The output is an NPN sinking open collector rated at Max. 20 mA (pull-up resistor required), powered from 5...24V DC with power consumption of ~8 mA. Electrical connection is via a round cable, 3 x AWG 24, with free cable ends or a 3-pin (2.8 x 0.5) mini DIN connector to EN 60529 (mating connector included). Process connections are offered as 1/4 in. NPT or G 1/4 in. (BSPP), 3/8 in. NPT or G 3/8 in. (BSPP), and 3/4 in. NPT or G 3/4 in. (BSPP).

Configuration Options

The three base models differ primarily in bore size and flow capacity. The BV1000 is the smallest, built around a 5 mm DN bore for very low flows and the highest resolution (up to 22,000 ppl). The BV2000 spans the broad middle of the range with DN bores of 6 mm, 8 mm, and related sizes covering flows from about 0.5...5 lpm to 2...35 lpm. The BV3000 uses the largest 12 mm DN bore for the top 5...65 lpm range with a K-factor of 210 ppl.

Within each model, part numbers encode material, end connection, flow range, and electrical connection. The TRG and TRN designators identify the wetted-material build, the numeric code (025 through 650) sets the flow range, and the trailing A or B suffix selects the electrical connection style — either free cable ends or the mini DIN connector. All variants share the same ± 3% accuracy, 25 bar operating pressure, and NSF/ANSI 61 and 372 certification.
