Direct-reading 150 mm variable area flowmeter for air, gases, and liquids with valved inlet/outlet options.
The Cole-Parmer Variable Area Flow Meter (0-150 mm) is designed for precise air and gas flow measurement in laboratory and industrial environments. This direct-reading variable area flowmeter eliminates complex conversion calculations, providing immediate and accurate flow rate readings. Featuring a valved flowmeter design, the valve can be installed either at the inlet (bottom) for positive pressure liquid and gas applications or reconfigured at the outlet (top) for vacuum systems, enhancing versatility.
Key technical specifications and applications include:
This flowmeter is widely used in biotechnology research environments for bioprocessing flow control and molecular diagnostics instrumentation requiring accurate gas and liquid flow regulation. Its robust construction ensures reliability in synthetic biology workflows and biomanufacturing pipelines where stable fluid dynamics are essential.
The 150 mm variable area flowmeter is a critical instrument for optimizing fluid flow parameters in clinical diagnostics, biomedical engineering, and laboratory process monitoring, offering a streamlined solution for flow measurement without the need for recalculations, improving efficiency across multiple research and industrial applications.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
