Economical, long-lasting flow measurement for clear liquids and gases
The McMenon FGM1190 is a durable and cost-effective Glass Variable Area Flowmeter designed for the accurate measurement of clear liquids and gases across a broad range of industrial applications. With a focus on long service life, visual clarity, and measurement flexibility, the FGM1190 is ideally suited for use in laboratories, OEM systems, and light industrial processes where precision and simplicity are key.
This flowmeter features a clear glass tube, providing a highly visible and immediate indication of flow rate, making it an excellent choice for operators seeking real-time, visual verification of fluid behaviour. With various tube lengths and taper configurations available, the FGM1190 can be tailored to meet specific flow requirements for low flow rate applications.
What sets the FGM1190 apart is its versatility. It supports multiple scale options, including direct measurement, values corrected to standard or normal conditions, or as a ratio of float to tube diameter along the tapered section. Each meter can be scaled and calibrated to the required accuracy class, in full compliance with VDI/VDE standards, ensuring confidence in every measurement.
Compared to the A6 series, the FGM1190 offers a greater flow capacity, making it the preferred option when slightly higher volumes are involved, while maintaining the same visual clarity and ease of use.
From research labs to custom-built OEM systems and light industrial environments, the McMenon FGM1190 is a trusted, economical solution that combines flexibility, reliability, and precision-engineered performance in one robust package.
