Cellular Modems

• Supports telecommunications in areas served by cellular telephone companies
• Requires analog service; check with local provider for coverage
• Conserves battery power by allowing datalogger to turn cellular transceiver on and off
• Current drain is < 0.5 mA quiescent, < 0.17 A stand-by, and < 1.8 A active

Landline Modems

Voice Synthesized Modems

• Allows a datalogger to vocally transmit real-time or historical data
• Enables a caller to access voice-synthesized information using a touch tone phone (including cellular)
• Supports by-passing the voice-synthesizer to allow the COM300 to function as a data modem
• Current drain is 100 uA quiescent, 140 mA voice transmitting

AirLink offers a variety of solutions to enable many telemetry applications to operate in the dynamic IP addressing environment of CDMA/1XRTT networks. ALEOS, in conjunction with AirLink IP Manager, enables applications to address remote devices by name (e.g. remote1.ddns.company.com). This dynamic DNS (DDNS) function is done automatically and securely any time the IP of the device changes. AirLink IP Manager then updates a DNS server. ALEOS can update IP assignment to host applications in addition to or instead of the AirLink IP Manager.

The unique intelligence within ALEOS enables virtually any type of remote device to connect via the public CDMA/1XRTT network. It can be used to replace existing landline, private radio, CDPD, and circuit-switched installations.

 Argonaut-SL

The Argonaut-SL (Side-Looking) is designed for horizontal operation, making a remote velocity measurement from an underwater structure (pier, bridge, channel, etc.) while allowing a simple and secure instrument mounting. The Argonaut-SL measures 2D currents in an adjustable measurement volume located at a range up to 120 m. The Argonaut-SL can be used for real-time or autonomous applications. The Argonauts belong to a class of instruments known as monostatic Doppler current meters. Monostatic refers to the fact that the same transducer is used as transmitter and receiver. A monostatic Doppler uses a set of acoustic transducers with precisely known relative orientations. Each transducer produces a narrow beam of sound perpendicular to the transducer face. The operation of a 3D Argonaut (with three transducers) During operation, each transducer produces a short pulse of sound at a known frequency that propagates along the axis of the acoustic beam. Sound from the outgoing pulse is reflected ("scattered") in all directions by particulate matter in the water. Some portion of the scattered energy travels back along the beam axis to the transducer. This return signal has a frequency shift proportional to the velocity of the scattering material. This frequency change (Doppler shift), as measured by the Argonaut, is proportional to the projection of the water velocity onto the axis of the acoustic beam. By combining data from three beams, and knowing the relative orientation of those beams, the Argonaut measures the 3D velocity. In the same manner, the Argonaut-SL measures 2D velocity in the plane defined by its two acoustic beams.

Flow Tracker

The SonTek/YSI FlowTracker Handheld ADV (Acoustic Doppler Velocimeter) uses a proven ADV technology in a compact, hand-held package to make accurate, high-precision water velocity measurements in natural streams, weirs/flumes, and open channels related to irrigation, stormwater, water treatment, and mining. Designed with the field user in mind, the FlowTracker easily attaches to top-setting wading rods and features an automatic discharge computation program that is based on USGS/ISO methods. Simple hand-held interface with real-time velocity display Automatic discharge computation program based on USGS/ISO methods Shallow-water 2D probe measures in depths as little as 2 cm (~1 in.); optional 2D/3D probe is available. Remote sampling volume of 0.25 cm3 located 10 cm from the transducer Flow Tracker software package Internal memory for 80,000 measurements (non-volatile) Temperature sensor Built-in recorder, battery power, and RS232 interface Mounting pin on ADV probe (Note: Complete mounting brackets for top-setting wading rods are available.) Velocity range:  0.001 m/s to 5 m/s (0.003 to 16 ft/s) Resolution: 0.0001 m/s Accuracy: 1% of measured velocity, 0.001 m/s No periodic recalibration required - invariant factory calibration Proven SonTek reliability
