virtually instantaneous. Recovery is a function of how long it takes to purge the samplingsystemupstreamfromthecell.Acceleratingthesamplepathflowrate will speed the response.

NOTE: TAI recommends that some bypass flow be permitted at all times. The bypass throttle meter is a part of the input manifold. Being so located means that the throttle valve lies between the sample side of the cell and atmosphere.

Without some bypass flow it is possible that atmo- sphere could diffuse into the sample line. Do not attempt to use the throttle valve as a shut off valve. Jamming the valve will damage the metering needle.

After the analyzer has been standardized, switch the selector valve to "Sample". Set the bypass flow so that the float is visibly elevated from the bottom of the tube and then readjust the sample flowrate to 0.3 scfh. No further adjustments are required.

NOTE: Although the bellows type valves used in the input manifold are among the best available, TAI suggests that the span gas be turned OFF at the cylinder when not in use, and the span line relieved of pressure before closing the analyzer span valve. Such a proce- dure will eliminate any possibility of the span gas diffusing into the sample path of the analyzer. Nor- mally, the recommended span gas composition con- tains a component of interest content of 3/4 the coars- est range of analysis. The component of interest

content of the sample gas, on the other hand, is usu- ally well within the finest range of analysis. Instrument sensitivity in Range #1 is 100 times greater than in Range #3. The user can readily see what even a minute rate of span gas diffusion would do to the validity of a Range #1 analysis.

212R specifications

Teledyne 212R is a state-of-the-art underwater acoustic modem designed for robust communication in various marine environments. This advanced device is based on established principles of underwater acoustics and modern digital signal processing technologies, making it an optimal choice for applications ranging from oceanography to underwater robotics.

One of the standout features of the Teledyne 212R is its high data transmission capabilities, allowing for reliable communication at distances of up to several kilometers depending on environmental conditions. The modem supports various data rates, enabling flexible adaptation to the needs of different applications. This versatility makes it suitable for both low-bandwidth telemetry and high-data applications, such as video streaming from underwater drones.

The Teledyne 212R employs advanced modulation schemes that enhance its performance in challenging conditions. These modulation techniques, combined with sophisticated error correction algorithms, ensure the integrity of data transmission even in noisy environments. This resilience is crucial as it enables the modem to maintain communication in the presence of marine life, background noise, and varying temperatures.

Another remarkable characteristic of the Teledyne 212R is its compact and rugged design. Built to withstand harsh marine conditions, the modem is encapsulated in a pressure-resistant housing, making it suitable for deep-sea operations. Its durability ensures longevity and reliability, reducing the need for frequent maintenance or replacement, which can be costly in remote underwater settings.

Moreover, the modem features an array of integrated sensors that allow for real-time environmental monitoring. This capability can be pivotal for research organizations studying marine ecosystems or for oil and gas companies conducting underwater surveys. The ability to collect and transmit environmental data alongside operational data streamlines data-gathering efforts.

Ease of integration is another key aspect of the Teledyne 212R. It is compatible with a multitude of existing marine technologies and communication protocols, allowing for seamless deployment in diverse systems. This adaptability is essential for users requiring collaborative operations across multiple platforms, such as Autonomous Underwater Vehicles (AUVs) and remotely operated vehicles (ROVs).

In summary, the Teledyne 212R combines high-performance data transmission, advanced modulation techniques, rugged design, and environmental monitoring capabilities. This makes it an essential tool for anyone engaged in underwater research, exploration, or resource management, establishing it as a go-to choice in the field of underwater communication.
