The reference and sample flowrates should be checked daily. The instru- ment is somewhat flow sensitive. Operating on Range #1 a change in flowrate of

0.1scfh will cause a corresponding change in sensitivity of from 1 to 20% of scale. On the coarser ranges, the change in sensitivity would be undetectable.

The sample path flowrate should be maintained at 0.3 scfh, the reference path flowrate at 0.1 scfh, and the bypass flowmeter float should be slightly above the bottom of the indicator glass.

When the cylinder pressure drops below 100 psig the reference supply should be replaced as the operation of the regulatorisquestionableatpressuresbelowthispoint.

When replacing supply cylinders, be sure to bleed the gas through the cylinder valve while installing the pressure regulator (see Section 2.3.4). It is also advisable to check the connections with soap water whenever a supply cylinder is changed.

NOTE: TAI strongly recommends that the analyzer run con- tinuously with gas flowing in both the sample and reference paths. During inactive periods arrange the input manifold so that zero gas is flowing. Gas sup- plies can be conserved by reducing the sample and reference path flowrates to less than 0.1 scfh and closing off the bypass flow completely.

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.
