Frequently Asked Questions

What is the DWYER VFB-85-SSV flowmeter used for?

The DWYER VFB-85-SSV is an acrylic inline variable-area flowmeter designed to measure the flow rate of air and compressed gases. It is commonly used in industrial pneumatic systems, HVAC applications, and process control where a visual scale display with +/-3% accuracy is sufficient.

What are the specifications of the DWYER VFB-85-SSV?

The DWYER VFB-85-SSV has a scale display type, +/-3% accuracy, Buna-N seals and O-rings, vertical mounting orientation, and measures flow in gallons. It includes a flow rate adjustment knob but does not include a pressure gauge. Maximum temperature is 120°F.

Where to buy the DWYER VFB-85-SSV worldwide?

3G Electric supplies the DWYER VFB-85-SSV worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this flowmeter to any country.

How to install the DWYER VFB-85-SSV flowmeter?

Install the DWYER VFB-85-SSV vertically in an inline pipe section, ensuring the flow direction arrow matches the process flow. Use compatible fittings and avoid overtightening to prevent cracking the acrylic body. For best accuracy, install with straight pipe runs upstream and downstream as recommended by Dwyer.
