Intent to Sole Source Vaisala Ultrasonic Wind Sensor

The National Oceanic and Atmospheric Administration (NOAA) is seeking information from potential qualified businesses to provide Vaisala WMT700 series heated 2-D sonic anemometers. The anemometers will be used to measure horizontal wind speed, direction, and variability for emergency response plume modeling. The required specifications include wind speed measurement performance, wind direction measurement performance, powering specifications, messaging specifications, and mechanical specifications. Interested firms should provide a brief narrative and documentation to support their capability and experience meeting the requirements. * The anemometers must have a wind speed observation range of 0-65 m/s and a starting threshold of 0.01 m/s. * The anemometers must have a wind direction observation range of 0-360 degrees and a starting threshold of 0.1 m/s. * The anemometers must have a powering specification of 9-36 V DC and a heating power supply requirement of 250 W. * The anemometers must have a messaging specification of 4 Hz readout update interval and units available in m/s, knots, mph, km/h, V, mA, Hz. * The anemometers must have a mechanical specification of dimensions 348 x 250 x 285 mm and weight of 1.8 kg.
