Monitoring compressed air usage in a factory or other operation where it is consumed is essential for proper system maintenance and attainment of energy efficiency goals. The ability to track down leaks and monitor compressed air usage enables stakeholders to work toward maximizing the return on an asset with substantial initial and operating costs.

Easy installation and simplicity of operation are advantages for any instrument applied in this manner, making compressed air flow measurement a good application for a thermal dispersion flow meter. With no moving parts and a simple operating principal, a thermal dispersion flow meter can be quickly installed and put into operation. A digital display of the flow measurement provides local information, and a networking connection or other signal output can provide for remote or centralized monitoring and data collection.

A cut sheet is included below that provides detail on technological, operational, and installation aspects of this simple and effective instrument. Share your flow measurement challenges with application experts, combining your own process knowledge with their product application expertise to develop cost effective solutions.

Safety Transmitters For Temperature and Pressure

Series One Safety Transmitter
United Electric Controls
Industrial history is replete with examples of catastrophic accidents. New safety technologies exist today that can prevent or mitigate mishap and disaster in fluid processing and other operations. Modern philosophy of plant safety brings a focus on a proactive approach. Process operators have a new sense of urgency to bring increased levels of safety to their operations.

The United Electric Controls (UE) Series One is a SIL-certified (Safety Integrity Level) transmitter designed solely for safety, alarm, and shutdown. With reliability, speed, and reduced nuisance trips an integral part of its design, the Series One is suitable for application in new installations, or easily integrated into existing operations.

A typical safety loop consists of sensors (such as a pressure or temperature transmitter), controllers, and final control elements. Most SIL-rated pressure transmitters require 300ms to communicate with the controller, then up to 500ms for the controller to send a signal to the final control element (such as a valve). This combined response time may insufficient for some applications. Incorporating the One Series Safety Transmitter, directly connected to the final control element, the total signal time is reduced to 100ms - a large and significant time savings when safe operating conditions have been breached. When used with blowers, pumps and compressors, the One Series makes up a complete safety system with a self-contained sensor, controller, and final control element (the switch) capable of SIL2 without additional safety instrumented function (SIF) components.

The below document provides detailed information about the Series One. Share your process safety challenges with the instrumentation specialists and combine your process knowledge with their product application expertise to produce effective solutions.



Opportunity For Improving Power Plant Heat Rate

Opportunities for improving efficiency at power plants
The large scale of most power plants provides a environment in which financial justification, or payback, of attempts to improve energy consumption can be justified. Even small improvements in efficiency can yield very substantial returns. The challenge to engineering and management is to select the projects which have the best overall probability of success and can be integrated into the process with the least amount of disturbance.

One area of the steam cycle that may be a candidate for improvement is the feedwater heater. This device is essentially a shell and tube heat exchanger used to recover waste heat from the process and use it to preheat boiler feedwater. Maintaining the correct liquid level in the feedwater heater is a key element of extracting maximum performance. Magnetrol, a globally recognized leader in the development of level measurement equipment, has produced a video showing how their technology can be used in an advantageous manner to others in regulating feedwater heater liquid level and achieving maximum efficiency.


Handbook on pH and ORP Measurement

Measurement of pH/ORP is a common operation throughout a number of industries. Obtaining true measurements and making correct interpretation of the results can prove challenging without solid working knowledge of the methodology and procedure involved. Certain effects have the ability to cause problems if not taken into consideration.

The book provided below, authored and provided by Yokogawa Electric Corporation, provides a comprehensive understanding of pH/ORP measurement and how to achieve reliable results. Basic information on the principles of measuring pH/ORP, construction of the sensing elements, and their basic use in process applications is provided.

A part of achieving accurate and reliable pH/ORP measurements includes the provision of sufficient electrode strorage conditions and proper maintenance. Prevention of common errors during maintenance and storage, as well as consistent detection of loop failures is important. This book describes how to avoid pitfalls and detect failures.

The book is accompanied with a frequently asked question and answer section as well as an appendix that includes helpful information like a Chemical Compatibility Table and a Liquid-Application-Data-Sheet, which can be used to describe the user’s application.

Safety Transmitters Achieve Safety Goals With Reduced Cost and Complexity

Process safety experts continually seek sustainable ways to improve the performance of safety critical loops, achieving risk reduction and safety goals in a cost-effective manner. Some view a reduction in complexity of safety related protocols to be a positive development. Traditional or historical approaches to deploying full blown safety systems were generally associated with great expense and high complexity, and still came up short on delivering the needed levels of risk reduction. Process control device and equipment manufacturers have responded with newer technologies and products that better address the safety needs of industrial processing.

In sensor subsystems, United Electric’s certified safety transmitter for pressure or temperature provides a less costly, simple path for process designers, instrument and control engineers, and maintenance personnel. The Series One Safety Transmitters combine several useful safety and monitoring functions into a single, easy to deploy device. Products are available for gauge pressure, differential pressure, and temperature applications. In addition to a 4-20 mA process variable output, the Series One has an embedded programmable high-capacity relay certified as a safety variable output. The Series One Safety Transmitter provides designers the option of a hard wired trip in less than 100 milliseconds, with a tenth of a percent repeatability, along with the monitoring functions of a traditional continuous analog output.

For equipment under control requiring protection, or processes where rapid excursions can initiate dangerous events, this unique pressure and temperature transmitter is addressing process safety time constraints, coupling issues with PLC and DCS units, and adding diversity to the safety instrumented function.

There is a whole lot more to learn about these "Safety right out of the box" industrial pressure and temperature safety transmitters.
