Vortex Flow Meters – Hot Tap & Compact Models

The new VN2000 vortex flow meters from Badger Meter are available from Bell Flow Systems and offer an ideal solution for a range of applications for measuring volumetric or mass flow of liquids, gases and steam. As a robust and reliable meter and with a large turn-down ratio these meters are an ideal solution for a range of applications.

The vortex meter technology lends itself well to harsh environments due to the lack of mechanical parts and solid construction. The VN2000 model is no exception and with its solid stainless steel construction and non-wetted sensors it takes this further offering a heavy-duty option with an exceptionally long life span, maintaining accuracy for many years and reducing maintenance costs over time in comparison to other metering technologies.

The VN2000 meters have the option of an integrated RTD temperature sensor, which is used for mass flow calculations and can also have a second external RTD connected to calculate energy transfer across a heat exchanger. The benefit of a high 204°C process temperature rating and a large flow range lends the meter to more applications especially where flow rates may span from low to high.

Two models are available in the range; a compact and a Hot Tap insertion model. As an insertion meter, flow in large pipes can be measured and the Hot Tap model can be used to measure pipes from 2 to 24” (50 to 1200mm). This hot-tap model also allows installation during high pressure applications without a system shut down, reducing costs and inconvenience involved when the meter needs to be removed and reinstalled.



When installing electronic flow meters there is always the possibility of incorrect wiring, having to open up the meter to fit wires into hard to reach terminal blocks can create errors and can also be time consuming. The VN2000 models are provided with a Power Plug, which eliminates wiring errors in the field. The plug connects to the enclosure meaning all wiring is done externally allowing for quick and easy connections. This includes wiring for the analogue output, Modbus and external RTD when used for energy calculations.
