Categories:
High visibility glass variable area flowmeter
A glass tube variable area flowmeter equipped with vertical internal threads or hygienic threaded connectors for installation, often used in food & beverage or pharma contexts where sanitary connections are needed. It is part of the VA Master FGM1190 series, sharing the same measurement principle and glass tube design.
The McMenon FGM1197 is a threaded glass tube variable area flowmeter engineered for direct-read visual measurement of gases and liquids in compact or modular systems. Designed for simplicity, reliability, and clarity, the FGM1197 delivers accurate flow indication where flanged connections are unnecessary or impractical.
Its clear tube and scaled float design allow for instant flow verification in small industrial loops, lab environments, and skid-mounted units. The lightweight construction and threaded ends support easy inline integration—making it an ideal solution for low-maintenance OEM builds or utility-focused measurement points.
In support of Eleven57 Energy’s mission to make instrumentation accessible and practical, the FGM1197 empowers small- and mid-scale operations with clear, trustworthy flow data.
Applications: lab gases, water treatment dosing, fuel line regulation, cooling loop control, mobile instrumentation modules.
Features and Specifications
Key dimensions and performance align with the FGM1190 family: line sizes from 1/4″ up to 2″ (including options like DIN 11851 dairy threads for the -97 design). This model variant allows mounting with sanitary fittings or union nuts. Flow ranges are the same (max ~17.6 m³/h water). Materials: float and wetted parts can be made of stainless steel or other alloys, and seals of food-grade elastomers if needed. Maintains long-term accuracy thanks to the fixed float guide ribs in the tube. Pressure rating ~18 bar; often limited by the type of fitting (food connections typically lower pressure).

Manufacturer specs note the -97 design type as intended for food industry connections, with performance data equivalent to other models.
Solutions and Applications
Targeted at applications that require easy disassembly or cleaning of the flowmeter: for example, measuring flow of ingredients in a dairy or brewery, or monitoring utility fluids in a pharmaceutical facility. The vertical thread/hygienic design allows quick removal of the meter for cleaning or calibration. Also used in general industrial service where a union connection is preferred for maintenance.
