Q46H/65 Chlorine Dioxide Monitor
By Pragya Gupta

Q46H/65 Chlorine Dioxide Monitor

ATi’s Q46H/65 Chlorine Dioxide Monitor provides an economical and reliable measurement system for water quality monitoring and controlling ClO2 treatment systems.

Continuous water quality monitoring of Chlorine Dioxide

Q46H/65 monitors use a polarographic membrane sensor to accurately measure ClO2 in water. The sensor operates much like a battery, generating a current that is linearly proportional to the concentration of chlorine dioxide in the solution. A ClO2 permeable membrane isolates the sensor from the measured sample and ensures that the measurement is interference-free.

Two versions of the sensor are available, a sensor intended for installation in a flow cell and a sensor intended for submersion applications. Requiring minimal maintenance, sensors are easy to use and easy to maintain. An integral RTD provides temperature compensation and allows the temperature to be displayed and transmitted from the monitor.

C21 Dri-Gas Sampling System
By Pragya Gupta

C21 Dri-Gas Sampling System

ATi’s C21 Dri-Gas Sampling System removes water vapor from the gas stream using a cold plate to condense the vapor and deliver a dry sample.

Dri-Gas sampling

Monitoring combustible or toxic gases in areas with condensing levels of moisture often results in premature sensor failure. Water condensing on sensor surfaces or within the sensor flame arrestor can be difficult to avoid due to widely variable ambient conditions.

ATi developed a solution to this problem with a gas sampling system that also conditions the sample by removing water vapor. The Dri-Gas sampling system draws gas samples from high-humidity vent stacks, ducts, wet wells, or other humid locations. The system removes water vapor from the gas sample by contact with a cold plate that condenses moisture and delivers a dehumidified gas sample suitable for toxic and combustible gas monitoring equipment. Excess condensate is pumped to a drain fitting on the bottom of the enclosure and can be collected if necessary.

C12-17 Combustible Gas Detector
By Pragya Gupta

C12-17 Combustible Gas Detector

ATi’s C12-17 Combustible Gas Detector is a stand-alone gas transmitter designed to detect potentially hazardous concentrations of combustible gases in ambient air.

Reliable detection of hazardous concentrations of combustible gases

ATi’s C12-17 Combustible Gas Detector is a stand-alone gas transmitter designed to detect potentially hazardous concentrations of combustible gases in ambient air. Gases and hydrocarbon vapors, such as methane, propane, butane, gasoline, toluene, hydrogen, and many others, can be reliably monitored in process buildings, analyzer enclosures, pump stations, gas compressor stations or anywhere gases or vapors may build up to explosive levels.

C12-17 Combustible Gas Detectors are three-wire transmitters available as either blind transmitters or with an integral LCD display that provides local indication of gas concentration, visible through the glass window in the explosion-proof housing. Gas transmitter units supplied with the integral display also contain a single alarm set-point and relay for local alarm purposes. This integral relay is a latching alarm that can be reset with a magnetic tool without opening the enclosure.

C12-17 gas transmitters can be connected directly to PLC, DCS, or computer-based alarm systems without additional hardware. Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit. When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas heating the active element and changing its resistance. The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration. The C12-17 Combustible Gas Transmitter has explosion-proof sensor assemblies that are made of 316 stainless steel for maximum corrosion protection. A sinter-bonded flame arrestor provides the gas diffusion path to the sensing elements while maintaining the flame-proof integrity of the assembly. Sensing elements are specially designed for maximum poison resistance and long life in harsh industrial environments, with sensor life typically 2 years or more.

B14 Gas Alarm Module Receivers
By Pragya Gupta

B14 Gas Alarm Module Receivers

ATi’s B14 Gas Alarm Module Receivers provide local alarm, display, and signal re-transmission functions for gas detection systems.

Monitoring hazardous gases in ambient air

ATI’s Series B14 Gas Alarm Module Receivers are compact electronic modules that provide local alarm, display, and signal retransmission functions for gas detection systems. The modules are designed to accept input from either two, three, or four-wire 4-20 mA transmitters located up to 10,000 feet from the receiver. They are ideally suited for use with any of ATi’s series A12, B12, C12, D12, or F12 gas transmitters.

B14 Alarm Receivers are DIN rail-mounted modules that can be supplied in single or multiple-unit enclosures. Gas concentrations are indicated directly in PPM, PPB, percent, or percent LEL with the display range selectable by the user. Each module provides separate caution, warning, and alarm setpoints with LED bar indicators of each alarm point. LED indicators flash on the initial alarm condition and change to steady when the alarm is indicated.

Modules contain individual alarm relays for each alarm setpoint. However, each relay can be assigned to any setpoint to allow multiple alarm functions at a single alarm point. Relays are configurable for either standard or fail-safe operation and for either latching or non-latching operation. A fourth LED alarm bar and relay are provided to indicate trouble conditions. The trouble alarm and relay will activate on the loss of input signal or if the 4-20 mA input drops below a specific value.

B12 Wet Gas Detector
By Pragya Gupta

B12 Wet Gas Detector

ATi’s B12 Wet Gas Detector offers reliable measurements in wet scrubber outlets for other gas streams saturated with water vapor.

Accurate gas measurement in wet gas streams

The B12 Wet Gas Detector was developed to provide reliable measurements in wet scrubber outlets for other gas streams that might be saturated with water vapor. These gas detector systems were specifically designed for monitoring strong oxidants (chlorine, bromine, chlorine dioxide, or ozone), acid gases (HCl or HF), and hydrogen.

Increasingly stringent air quality requirements have led to the expanded use of wet scrubber systems to control pollutant gases released as air emissions. Chlorine storage facilities and chemical process plants are frequently required to scrub exhaust gas streams to remove halogen and acid gases. Unfortunately, monitoring reactive gas concentrations in moisture-saturated air streams presents problems for standard diffusion gas sensors. Condensing water in these airlines can quickly blind standard diffusion transmitters, rendering them inoperable.

The basic B12 Wet Gas Detector system consists of a loop-powered 2-wire transmitter and a corrosion-resistant sensor specifically engineered to operate at 100% RH. Gas sensors are designed for direct insertion into vent stacks, or may be used in a flow cell if a sample can be pumped to the sensor. When remote display and alarm relay functions are required, the B12 wet gas transmitters can be connected to ATI’s B14 Gas Alarm Module. This receiver system will provide a direct digital display of gas concentrations, plus 3 alarm set points, a remote alarm reset input, and retransmitted 4-20 mA output. The B12 wet gas transmitter may also be used separately and tied directly to the user’s DCS, PLC, or other equipment. Either way, the B12 Wet Gas Detector is an excellent solution to a difficult gas monitoring problem.
