The VN2000 Hot Tap Insertion Vortex Flow Meter measures the volumetric or mass flow rate of steam, gases or liquids over a large flow range.
The VN2000 Hot Tap Insertion Vortex Flow Meter measures the flow of steam, gas or liquids over a large flow range. The meter is a heavy duty design engineered to stand up to the most abusive environments inside and outside the pipe.
The vortex sensing element is CNC machined out of one piece of solid stainless steel. 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.
• Removable Insertion/Extraction Tool. Aids in installation or removal in high pressure applications
• 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
• Standardize on an insertion bar that can measure line sizes 2…36 in.
• Reduced noise interference with dual piezoelectric sensors and filtering
• Machined safety stop provides constant seal, will not leak
• Standard model handles process temperatures up to 400° F (204° C)
• Reduced maintenance due to:
– No moving parts
– Heavy duty welded stainless steel construction
– Piezoelectric and temperature sensors never touch process fluid
– No recalibration necessary
– No pins or screws to corrode and rust
The Dynasonics® TFX-500w transit time ultrasonic flow meter measures the volumetric flow of clean water in pipes 10 in. or smaller. Its clamp-on design allows the meter to be installed without cutting or tapping the pipe.
Robust portable flow meter for long-term monitoring of full pipes
TFXL ultrasonic transit time flow meter measures most clean liquids and liquids with small amounts of suspended solids or aeration, such as surface water or sewage.
The ModMAG® M1000 amplifier is suited for bidirectional flow measurement of liquids >5 μS/cm (>20 μS/cm for demineralized water). It combines all the opportunities of price with high level performance.
