AW-Lake - Model JV-BB -Positive Displacement Gear Flow Meter
The JV-BB Positive Displacement Flow Meter is part of AW-Lake’s “Next-Generation” line of Gear Meters and is the result of decades of experience, listening to customers and extensive and diligent study of the latest technologies available. These high performance flow meters have tighter machining tolerances, higher resolution, higher pressure rating, and improved accuracy over their predecessor the JV-KG meter and as a result, reduce operational costs. This meter maintains high accuracy and repeatability, despite changing viscosity conditions, up to ±0.25% accuracy with select sensors. Applications well suited to the JV-BB meters include chemical injection & dosing systems, fuel measurement, test stands, hydraulic positioning systems, and coolant & lubrication monitoring.
- Measuring Accuracy:±0.5% over full range with 30cP fluid, ±0.25% optional with select sensors
- Six Flow Ranges:0.005 - 120 gallons per minute | 7.2-172,800 gallons per day (see specs below for ranges of each meter size)
- Pressure Rating:Up to 6,000 psi
- Calibration:7-point logarithmic calibration
- Output Options:Wide variety of options: see "Choose Your Sensor" tab below for details
The JV-BB positive displacement flow meters build upon the performance you expect from us and take ease of use and durability to the next level, offering greater efficiencies in operation with higher resolution, higher standard pressure rating (up to 6,000 psi), wider turndowns, and improved accuracy – even in changing viscosity conditions.
- Eliminate Waste – Maintain repeatable and accurate flow measurement, independent of changing fluid conditions. Track and report usage to quantify product/process quality, pump performance, or material levels.
- Reduce Costs – By using the correct amount of expensive/costly fluids in your process and not overdosing, you can reduce material costs. And with proper lubrication or chemical dosing you can reduce maintenance costs.
- Improve Product Quality – With flow meters that can ensure ±0.1% repeatability, you are able to maintain consistency in your processes by assuring each batch is the same. Despite long and continuous operation, these meters perform at the same level month after month… year after year.
- Operate with Ease – Paired with our smart EDGE family of flow sensors there is one easy to learn set-up procedure available via phone or PC app. Our friendly & knowledgeable staff of Application Engineers are here to help you select the right meter and get you up and running quickly.
- Enjoy Flexibility – The new meters were designed to seamlessly integrate with the EDGE sensors, which are available in panel mount, local mount, and battery, loop, or DC powered displays. Choose your output as well: Frequency or Analog (voltage or 4-20mA), or Modbus.
