To check, service or maintain existing flowmeters, we recommend our non-intrusive handheld ultrasonic flowmeter STUF-200H.

For long-term flow monitoring, consider wall-mount ultrasonic flowmeter STUF-300Fx or magnetic flowmeter DigitalMag888. For thermal energy measurement, we recommend our STUF-300Rx products. They are good for both hot water and chilled water applications; efficiency monitoring and improvement of liquid-based heating /cooling systems, including solar/geothermal systems.
