Recorded Webinar: Detection Technologies for Toxic and Combustible Gases

This recorded webinar, presented by MSA, provides an excellent overview of the history of gas detection and the technologies used today. MSA is the world's leading manufacturer of safety products designed to protect people throughout the world.

Industrial gas detectors are used in a wide variety of chemical plants, refineries, water treatment plants, and other manufacturing facilities to continuously monitor and detect toxic or combustible gases and vapors. They are equipped with audible and visual alarms to alert personnel to the existence of these conditions. The major components for industrial gas detectors are the sensor, the detector, the transmitter, and the annunciator. Gas detection systems are available as single point sensing or multiple point sensing capabilities, and in fixed position or portable configurations.

Celebrating Our Veterans on Veterans Day

Veterans Day is a day of observance and celebration for those who have served in the United States military. Veterans Day was originally called Armistice Day because of the November 11 Armistice that ended World War I. In 1954 it was officially changed to Veterans Day to include Veterans of all wars. This holiday honors those who took an oath to defend the United States and our Constitution, from all enemies, foreign and domestic. Through the observance of Veterans Day, we remind ourselves of our Veterans patriotism, love of country and willingness to serve and sacrifice for the common good.

Power Specialties thanks our Veterans, past and present, for serving our country and protecting our freedom.

Electric and Pneumatic Damper Drives for Combustion Air and Flue Gas

Download the Damper Drive Catalog Here

There are more than 45,000 industrial and commercial boilers larger than 10 MMBtu/hr in the United States with a total fuel input capacity of 2.7 million MMBtu/hr. One way to improve the efficiency of these boilers is to improve the combustion control system.

Current combustion control systems lack continuous carbon monoxide and nitrogen oxide emissions monitoring capability and the automated controls needed to improve fuel performance. A novel combustion control system, along with gas sensors, sets the opening of fuel and air inlets based on flue-gas concentrations. Continuous feedback from measurements of oxygen, carbon monoxide, and nitrogen oxide concentrations enable the control system to improve combustion efficiency while maintaining low carbon monoxide and nitrogen oxide emissions and allows continuous monitoring of boiler performance.

Combustion air and flue gas damper drives fill a critical role requiring safety, accuracy and reliability of the combustion control system. The proper damper drive delivers quality, power and performance providing precise control and speed increases the BTU/Fuel ratio and increases the MW/Fuel ratio.

Rotork offers a full-line of electric and pneumatic damper control solutions for the isolation and control of combustion air and flue gas. Our products improve the efficiency and reliability of large and small boilers, furnaces and process heaters.

Top Five Tips for Choosing a Flow Meter

The wide range of flow technology alternatives on hand can make it a confusing task to select the right flowmeter. A wide range of factors can influence the selection of flowmeter, of which only one is the cost. Including the fluid type, application environment, working parameters such as temperature, pressure and flow rate, flow meter technology, requirements for precision and repeatability, reliability, installation limitations, maintenance requirements, and instrument life cycle are many considerations to consider. Below are our top five criteria when selecting a flow meter.

Regulations, compliance
1. What local, state, regional or national regulations impact the measurement location?
2. Are there additional recording, data logging or calibration verification requirements to comply with regulations?
3. What agency approvals must the flow meter have?
Fluid type at the measurement point
1. Dry or wet gas conditions may affect sensors
2. Corrosive components in oil may affect sensor material selections
3. Flow back contains mixtures of oil, gas, solids, chemicals, and water that must be separated
Fluid conditions
1. Does the accuracy spec of the flow meter change based on the composition of the fluid type?
2. Does the fluid composition change over time?
3. What is the pressure and velocity in the pipe? Is it constant?
4. Are there installation limitations (straight pipe runs, limited access to the pipe, tight spaces)?
Additional equipment
1. Does the flow meter require additional equipment or instrumentation to operate successfully at the point of measurement?
Additional calculations

Will you need to do additional calculations to determine an accurate flow rate?

Top 10 Reasons Why ProSafe-RS Safety Instrumented System (SIS) Is the Fastest Growing Safety Control System

Before ProSafe-RS, DCSs and SISs were typically supplied by different vendors and required extra engineering for the individual systems and interconnections. Furthermore, these systems were more difficult to master and operate as they had different interfaces. ProSafe-RS overcomes these hurdles through complete integration with Yokogawa’s CENTUM DCS – an industry first. The ProSafe-RS has been a global success since its debut in 2005, and is continually being improved.

ProSafe-RS has a unique and excellent dual architecture that is based on Yokogawa’s supremely reliable DCS technology. The SIS has a modular design, and dual architecture is implemented inside each module. And the modules themselves can be installed in a dual redundant configuration. This is controlled by the SIS and is fully transparent to the user. This approach maximizes both safety and availability, independently and simultaneously. This flexible system configuration makes it possible for the user to configure redundancy on a module by module basis, achieving the required availability in each system component.

A Better Solution for Open Channel Flow Measurement

Open channel flow instruments require accurate measurement of the surface level of a liquid. A flume, channel or structure which has a known characteristic flow per measured head, together with the measured liquid level, accurately define the flow rate through the system.

Hawk transducer for water applications.

Traditional systems use a stilling well and pressure level measurement system to measure the liquid level in the structure. Sedimentation and buildup will over time cover the sensing part of a pressure measurement system, leading to inaccurate or completely failed measurement. Buildup can also block passages to a stilling well, making any level measurement inaccurate or false. Regular cleaning of measurement systems and stilling wells is required to ensure operation.

The level instrumentation control manufacturer Hawk Measurement uses a non-contact Acoustic Wave sensor, positioned directly over the channel or flow structure, or above the stilling well if required, to provide maintenance free, reliable measurement of the liquid level.

The Hawk Sultan Flow instrument calculates flow through a range of standard measurement structures, and can also be individually tailored to a non-standard flow characteristic. Measurements are temperature compensated, and sensors are available covering a broad range of water, waste-water, irrigation and environmental monitoring applications.

Powerful measurement pulses keep sensor facings clean from moisture and condensation, ensuring maximum performance in all conditions. Continuous and switched outputs are included, as well as local totalizing of flow, and the ability to provide pulsing outputs per flow volume to external counting devices.
