The VN2000 Compact Insertion Vortex Flow Meter measures the flow of steam, gas or liquids over a large flow range. The meter includes a mounting assembly alignment pin to simplify the installation. The meter is designed for specific pipe sizes and
includes parts for installation.
The vortex sensing element is CNC machined out of one piece of solid stainless steel and engineered to stand up to abusive environments inside and outside the pipe. The dual ceramic piezoelectric sensors are bonded inside the vortex element, which is press-fit to the stainless steel insertion bar and completely welded together. There are no internal o-rings or seals of any kind and absolutely no leak paths into the sensors or electronics. Our sensors do not touch the process fluid, which gives them an almost unlimited life span.
Ideal for accurately measuring liquids, compressed air and saturated steam. No moving parts and virtually maintenance-free once installed.
• Reduced Installation Errors. Mounting Kit included to simplify the installation and ensure proper installation depth and orientation for a specified pipe size
• Reliable measurement for steam and a variety of fluids. Heavy duty design engineered to stand up to the most abusive environments inside and outside the pipe
• Reduced Maintenance Costs and Spare Parts. No internal o-rings or seals of any kind and absolutely no leak paths into the sensors or electronics. Our sensors do not touch the process fluid, which gives them an almost unlimited life span.

• Measure volume or Btu of liquids
• Measure volumetric or mass flow rate of steam or gas
• Lower profile insertion meter for pipes 2…24 in.
• Simplify installation with an insertion meter and pipe mounting assembly designed for the specific pipe size
• Reduced noise interference with dual piezoelectric sensors and filtering
• Standard model handles process temperatures up to 400° F (204° C)
• Reduced maintenance due to:
– Heavy duty welded stainless steel construction
– O-ring-free element
– No moving parts
– Piezoelectric and temperature sensors never touch process fluid
