Badger Meter has introduced the VN2000 hot tap and VN2000 compact insertion vortex flowmeters for measuring the volumetric or mass flow rate of steam, gas or liquids over a large flow range.
The meters’ versatile design is capable of measuring water as low as 1.32ft/s and super-heated steam up to 250ft/s.
They are well-suited for applications involving energy flow and heat transfer of saturated steam used for heating commercial buildings, hospitals, and multi-building campuses.
Constructed of solid stainless steel, the VN2000 flow meter’s heavy-duty construction stands up to the most abusive environments inside and outside the pipe.
Its measuring element is constructed of a single piece of welded and machined stainless steel with non-wetted sensors and no internal O-rings or seals to allow steam to leak into the sensing electronic elements.
The meter’s piezo-electric and temperature sensors never touch the process fluid as they are completely enclosed and protected in a stainless steel body, giving them an exceptionally long life span.
Due to the durable design with no moving parts, the VN2000 meter does not require servicing and maintains accuracy for many years.
Cheryl Ades Anspach, marketing manager at Badger Meter, commented: “The VN2000 insertion flowmeters are very robust and dependable. The lack of moving or wearing parts ensures the readings will not change over time and long-term accuracy is always constant.
“Through the use of an internal resistance temperature detector (RTD), the flowmeter software compensates for changes in temperature to achieve a precise mass flow measurement. And due to its design, the meter does not require servicing. Users will see a cost savings over time compared to many other flow measurement solutions"
The VN2000 hot tap insertion vortex flow meter handles process temperatures up to 204˚C, and can measure line sizes of 2-48”.
For volumetric flow, the meter achieves an accuracy of ±1.0% with repeatability of ±0.25%.
Vortex sizing application software determines the precise scaling factor for an application.
For applications where downtime must be avoided, the VN2000 hot tap flowmeter can be installed or removed during operation, without shutting down the process.
An optional hot tap insertion/extraction tool makes it easy to install the meter even in high pressure applications.
The removable insertion/extraction tool is designed to eliminate the weight, bulkiness, and equipment malfunction that may occur when insertion tools are permanently connected to the instrument.
The VN2000 compact meter is also easily installed using a mounting assembly with pin and an arrow machined into the mounting assembly that shows the direction of flow.
