Badger Meter RVL Specifications

Vortex Flow Meter

RVL Series

DESCRIPTION

The RVL liquid flow meter uses vortex-shedding technology with embedded piezoelectric pressure sensors. The meter has no moving parts, and any potential for fluid contamination is eliminated by the non-metallic corrosion-resistant body materials. The meter includes a compact plug-in transmitter module with two-wire 4…20 mA or three-wire pulse output. All electronics are housed in a corrosionresistant enclosure. Units can be recalibrated and reprogrammed in the field.

APPLICATION

The RVL is perfect for aggressive or easily contaminated fluids.

• Ultra-pure water distribution

• RO/DI skids

• Cooling water

• Chemical injection

• Nonabrasive slurries

OPERATING PRINCIPLE

Operation of the RVL vortex flow meter is based on the vortex shedding principle. As fluid moves around a strut, vortices (eddies) are formed and move downstream. They form alternately, from one side to the other, causing pressure fluctuations that are sensed by a piezoelectric crystal in the sensor tube. The frequency of the vortices is directly proportional to the flow rate.

CONSTRUCTION

The precision machined bodies provide quality end fittings, while avoiding ionic contamination. There are no metallic wetted parts, gaskets or elastomers in the meter. The body material selected is homogeneous throughout the flow path.

OPTIONAL SOFTWARE

An optional software utility kit is available to configure the RVL 4…20 mA output. (The pulse output is not field configurable.) Part number RVS220-954 contains a RS232 nine-pin cable, software CD, TTL to RS232 converter and a board interface cable. The program enables easy configuration of span, damping and units of measurement.

Material Selection

MATERIAL SELECTION

When choosing the best flow meter for a process, review the concentration, operating temperatures and operating pressure of the fluid being measured. In a thermoplastic piping system, choose the same material for the meter and the pipe wherever possible to maintain fluid compatibility and aid in bonding the materials. The table below shows the compatibility of fluid types with thermoplastic materials.

FLUID CONSIDERATIONS

In vortex flow meters, fluids with high viscosities tend to dampen the formation of vortices and reduce the effective range. Viscosities above 1 cSt raise the minimum readable flow rate, reducing rangeability. The effect is linear to viscosity. Particles and internal bubbles do not usually affect vortex meters. In slurry services, PVDF models typically work very well. Slurries containing grit can wear down the bluff body over a period of time and long fibers can catch and build up on the bluff, decreasing accuracy.

Liquids with specific gravities higher than 2.0 adversely affect the permissible amount and duration of over-flow range.
