General Monitor's Model IR700 features a precision IR point sensing element that provides reliable protection against the hazards of carbon dioxide gas leaks. The IR700 offers a true fail-to-safe design for dependable gas detection performance, heated optics to eliminate condensation and a dirty optics indicator informs the user the device must be cleaned before the lenses are entirely blocked, thereby reducing downtime.

Carbon dioxide is an inexpensive and versatile gas that is useful in diverse applications from beverage carbonation to enhanced oil recovery techniques. While nonflammable and fairly innocuous, leaks can be dangerous. Exposure to atmospheric concentrations above 5,000 ppm is considered unhealthy, making careful monitoring crucial at lower levels. Atmospheric concentrations at 1% v/v (10,000 ppm) will make some people feel drowsy while concentrations of 7% v/v and higher can lead to symptoms including dizziness, headache, visual and hearing dysfunction, and unconsciousness.

Designed for accurate, reliable, low maintenance level measurement in extreme conditions, the K-TEK range delivers:

- The ability to accurately measure two liquids in the same vessel.

- The only magnetostrictive transmitters to be IEC61508 certified for SIL2 and SIL3 applications.

- Laser transmitters measuring liquids or solids at 30 metres plus with no false reflection

K-TEK's guided wave radar level transmitter for measuring level in saturated steam

Case Study: An ABB K-TEK LM200 laser level transmitter is helping a well-known wastewater plant return to reliable level measurement, after issues with a competitor’s hydrostatic level transmitter.

The company uses level measurement to activate pumps to a pre-treatment plant when the water reaches a pre-determined volume. Previous measurement techniques failed to cope with the amount of debris and grit present in the effluent, which clogged up sensors, causing inaccurate readings and making them difficult to re-calibrate.

The ABB K-TEK LM200 laser transmitter is ideal for this application and was purposefully designed for the measurement of dry bulk solids, opaque liquids, and slurries at distances of up to 200 feet. It features an advanced timing system and sophisticated, self-correcting signal processing function that allows it to accurately and reliably measure level, distance, and position in the harshest of conditions.

ABB solves level measurement problem for wastewater plant

Featuring a potentiostatic three-electrode design for superior accuracy, the rugged and low-maintenance Triton® DO9 Dissolved Oxygen Analyzer from Electro-Chemical Devices (ECD) is ideal for the continuous measurement of trace levels (ppb) of dissolved oxygen in aqueous systems supporting steam turbine-driven electric power generation plants.

Highly reliable monitoring of boiler feed water is crucial to ensure that dissolved oxygen is only present in trace quantities throughout the steam cycle. Excessive oxygen concentrations can result in corrosion damage to steam cycle components. By continuously and directly monitoring ppb levels of dissolved oxygen, the Triton DO9 Analyzer eliminates grab sampling errors and ensures reliability.
