The Dual Frequency Doppler (DFD) technology significantly improves the ability of the Polysonics SX30 to operate in what were previously considered marginal applications for Doppler flowmeters. Unlike conventional Doppler flowmeters, which operate at a single frequency, the Polysonics SX30 generates two independent ultrasonic signals at different frequencies. By correlating these frequencies, the instrument identifies and eliminates noise errors from sources such as variable frequency drives. The operation of the Polysonics SX30 is enhanced by an Expert System which allows the flowmeter to automatically “learn” the application parameters. As a result, the Polysonics SX30 can be set up in four easy steps and at a fraction of the time necessary to configure competitive flowmeters. The design features a sealed membrane keypad making the unit fully weatherproof. Large keys make it easy to enter data and navigate the on-screen menu—even with gloved hands. Features and Benefits • Accuracy to ±1% • Simple and easy to use • Excellent noise immunity • NEMA 6 environmental sealing • Up to 24 hours battery operation • Powerful 90,000 point data logger • Serial interface port for data retrieval via HydraScan software • Universal AC adapter charging socket
