Wireless communication has seen increasing prevalence in the industrial process measurement and control field for a number of years. Vendors, in response to customers' desire to incorporate the technology across an ever widening array of application scenarios, continue to develop and release new products and technologies that expand the potential for industrial wireless communication. One company, Analynk Wireless, is now shipping a new version of their patented wireless antenna for hazardous areas. We published an article last week about their cellular device data links.

The newest Analynk Hazardous Area Antenna provides remote data links for customers using Iridium, GPS, and GLONASS. This new product adds to the company's already expansive line of wireless communication products specifically designed for industrial application, providing wireless data links to mobile or very remote locations not always accessible to other communication networks.

Analynk's antennas are operable across a very wide temperature range and provide substantial impact resistance, signal output, and ratings for hazardous environments.

Contact a product specialist about the Analynk Wireless products and discuss the potential benefits of incorporating or expanding wireless data links of all types into your operation.

Industrial process measurement and control is not restricted to the factory floor and fixed installations any longer. Increasingly, there are remote, as well as mobile, installations with a need for remote control command execution, or producing useful and valuable data that can be put to use by operational, safety, and financial stakeholders. Industrial process operators, as well as other levels of the business enterprise, can now have real time access to information that can be used for business and industrial process improvement.

The advent of wireless communications made gathering data from, and issuing control commands to, remote and mobile installations possible. A continuing path of vendor innovation and improvement has:

• Improved wireless technology reliability in the industrial setting.
• Expanded industrial wireless communications applicability.
• Simplified the implementation of a wireless communications strategy in an industrial process measurement and control setting.
• Reduced the cost and timeline associated with installation of a wireless solution.

Analynk Wireless, a designer and manufacturer of wireless devices and instrumentation for the process control industry, is adding newly designed cellular devices to their already extensive industrial wireless communications offering.  The deployed devices will feature cellular/GPS/GPRS connectivity to allow worldwide transmission and receipt of data via cellular and internet, providing remote monitoring and control through the use of additional connected devices.

The applications and opportunities for process improvement through wireless data gathering are vast. The cost and simplicity of these systems make them an option to be considered. More information is available from product specialists, with whom you can discuss your application ideas.

New Product From Cameron - CamCor Coriolis Flow Meters

Whether it's high viscosity crude oils, ultra-low flow conditions or applications at the extremes of temperature, Cameron's new CamCor™ range of Coriolis flow meters deliver value beyond the whole-life operational benefits associated with non-mechanical architectures.

CamCor comes in two architectures, CamCor CT for custody transfer, where the emphasis particularly is on high accuracy, and the Cameron CamCor PRO for process operations.

CamCor CT offers flow rate accuracy of ± 0.1% for liquids, as a result of its deep “U” shaped dual sensors, with outstanding zero stability performance (0.071 lb/min for 2” model). The range includes models purpose-designed for application extremes, covering temperatures from -200°C (Cryogenic/ LNG) up to 350°C. Nominal sensor sizes go from less than 2mm to 250mm, with 1/4” to 10” end connections, offered in ANSI class 150 to 900, other flange types, threaded, or Tri-Clover.

The unit is manufactured of 316/316L stainless steel and Hastelloy Alloy C22.

The CamCor PRO Series possesses a flow rate turndown ration up to 50:1, flow rate accuracy of
+/- 0.2% and density accuracy of +/- 0.003 g/ml. It comes with the same transmitter, output, communications, diagnostics and configuration as the CamCor CT and is available in four nominal sensor sizes, from 6mm to 50mm, with 1/2” to 2” end connections in ANSI flanges and Tri-Clover.

A new multivariable vortex flowmeter has recently been added to the product line at MS Jacobs & Associates. It is intended for industrial process measurement and control. The AX Series, from Azbil North America, utilizes a vortex shedding velocity sensor, solid state pressure transducer, and resistance temperature detector in a single unit to allow accurate measurement of mass flow in gases, liquids and steam. The combination of multiple variable measurement in a single package simplifies installation and setup cost, while reducing potential leakage paths of an arrangement employing separate instruments for each variable. The AX Series is available for in-line or insertion installation. Your product sales engineer can provide a sizing guide and other assistance in selecting and configuring the best product for your application.

Selecting the Right Valve Type - Gate Valves

When it comes to controlling flow in an industrial fluid handling system, there are more choices than you can count. The journey of focusing in on the best option for your application can be shortened by employing some coarse filters to the vast array of available products and technologies, discarding choices that do not meet the basic criteria deemed essential to a successful project.

A common type of industrial valve is the gate valve. It regulates fluid flow by sliding a round or rectangular wedge, known as the gate or disc, in the flow path of the fluid. When the gate is fully retracted from the fluid path, flow is enabled to its fullest. Gate valves close by sliding the gate, which is commonly attached to a threaded shaft of other similar mechanism, into the path of the flow until it is fully obstructed. It is the movement of the gate, combined with the way in which a gate valve is constructed, that attributes this valve class with its positive and negative values.

Positives for gate valves:

• When fully open, there is low resistance to fluid flow. The opening in the valve tends to mimic the cross sectional characteristics of connected piping and fluid can flow through the valve without a directional change.
• Changing the gate position (opening or closing the valve) does not require as much force or power as some other valve types, due to the gate movement being perpendicular to the flow direction.
• Gate valves work in both directions. The flow in the connected line can be reversed and the valve function is unimpaired.
• The gate valve assembly tends to be shorter in length along the path of flow than some other designs.



Gate Valves in Process Pipeline

• The rate of closure is generally slow, providing a graduated reduction in fluid movement and reduced physical shock to the piping system.

Operating or construction characteristics that may be an advantage to gate valve employment on one application may prove a disadvantage in another.

“Not so positives” for gate valves:

• When the valve is open, the seals are exposed to the fluid flow. Foreign material, even elements of the process fluid, can deteriorate or contaminate the seals and impact the sealing of the valve when closed.
• The gate valve opens at a comparatively slow rate, making it unsuitable for applications that may require rapid or immediate shutoff.
• The service and maintenance space requirements, often extending overhead of the valve, can be substantial and may impact the ability to locate the assembly where desired.
• Gate valves are not well suited for throttling fluid flow. Fluid flow through a partially open valve of this type may cause the gate to vibrate.

There are certainly more elements involved in proper valve selection than are shown here, but this quick check may help you focus on gate valves or another technology for further consideration. It is always beneficial to bring in experts and those with experience to participate in the selection process.
