The JV-UF positive displacement flow meters were designed specifically for low viscosity fluids, as found in the oil and gas or chemical processing sectors. The internal design of the JV-UF meter delivers greater precision than other meters and an expanded list of low viscosity fluids it can handle.

  • 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.
