( Brand: Dwyer ), ( Manufacturer Part Number: VFA-7 )
The VFA-7 Visi-Float Flowmeter from Dwyer Instruments is a highly accurate and reliable flowmeter designed for measuring gas flow rates in the range of 5 to 50 Standard Cubic Feet per Hour (SCFH). This flowmeter features a unique visi-float design, which allows for easy and accurate readings by using a floating element that rises and falls with the flow of gas.
The VFA-7 is constructed from high-quality materials, including a stainless steel housing and a glass tube, making it durable and resistant to corrosion and wear. The flowmeter also features a large, easy-to-read dial that displays the flow rate in real-time, as well as a calibrated scale for easy reference.
One of the key benefits of the VFA-7 Visi-Float Flowmeter is its simplicity and ease of use. It requires no power source, making it ideal for use in remote or hard-to-reach locations. The flowmeter is also easy to install and maintain, with no moving parts to wear out or require replacement.
The VFA-7 is also highly accurate, with a repeatability of /- 0.25% of full scale, making it suitable for use in a wide range of industrial and commercial applications. It is also certified to meet the requirements of the American Gas Association (AGA) and the National Institute of Standards and Technology (NIST), ensuring that it meets the highest standards of accuracy and reliability.
In summary, the VFA-7 Visi-Float Flowmeter from Dwyer Instruments is a highly accurate and reliable flowmeter for measuring gas flow rates in the range of 5 to 50 SCFH. Its unique visi-float design, durable construction, and easy-to-read dial make it simple to use and maintain, while its high accuracy and certification to AGA and NIST standards make it suitable for use in a wide range of industrial and commercial applications.
