GF Piping’s 3300 Series Ultrasonic Flow Monitoring System is designed to provide added flow measurement accuracy of the entire flow stream in industrial, water treatment, wastewater and municipal water systems. The 3300 Series Ultrasonic Flow Monitoring System advances the use of Doppler ultrasound technology by utilizing “Advance Spectrum” signal processing in measuring the entire flow stream. The result is reliable, power-efficient, low cost of ownership, and liquid flow monitoring in installations where remote solar-powered operation is most effective. The 3300 Flow Series features the Ultrasonic Flow Meter that is tailored for top performance in water/wastewater and industrial waste applications and municipal water installations. The Model 3300 system operates from a 9VDC power source or AC power utilizing a power converter. An optional solar panel based battery-charging unit is available that enables unattended, stand-alone operation for up to seven years. This unit also boasts a vandal-resistant configuration via a dual password system that allows for local or remote downloading of logged data.
