Orion Instruments, a world class manufacturer of magnetic level indicators, level switches, and level transmitters, has released a new product for use in the industrial process measurement and control field. Their Jupiter Model JM4 magnetostrictive transmitter incorporates the company's many years of research, development, and field experience to provide a safer, simpler, and smarter transmitter for liquid level measurement and control.

The new model from Orion boasts level measurements with accuracy as high is +/-0.05" (1.27mm). The transmitter head can be rotated up to 310 degrees with an option for remote mounting. Variants are available for direct insertion or external mounting, with approvals for a number of area classifications. There are other valuable features to this series of level measurement instruments that reflect Orion's expertise in the field.

Browse the new product brochure included below. It provides illustrations of the product and its operating principle, along with dimensioned drawings and a listing of all the product options and variants. You can always obtain whatever information you need about Orion level measurement instruments from a product specialist. Share your liquid level measurement challenges and requirements with them for recommendations on the best solutions.

Coriolis mass flow meters are widely used throughout the process measurement and control field. Their basic operating principle, combined with modern sensor and signal processing technology, provide a list of positive aspects.

Directly measure mass flow rate based on the principle of measurement.

Measure the mass flow rate with high accuracy of ±0.1%.

Provide a wide usable measurement range.

Deliver density measurement based on oscillating frequency.

Not materially impacted by fluid viscosity or density.

Coriolis flowmeters also do not need straight pipe sections upstream or downstream of the flowmeter. They also have the ability to measure non-conductive fluids. 

I have included an interesting video, produced by Yokogawa, a world class manufacturer of industrial process measurement and control instrumentation. It provides a clear and insightful illustration of the Coriolis principle and how it is used to provide accurate mass flow measurement.

Share your process measurement and control challenges with an instrumentation specialist. Combining your detailed process knowledge and their product application expertise will yield positive solutions.

Miller Energy Expanding Customer Connectivity With New Website Function

Engineering technician inspecting precision part
At Miller Energy, use website chat to connect directly with technicians
and product specialists.
Miller Energy will be rolling out real time chat on their website in early February. This new feature is another in a long line of continuous improvements the company has brought on line to better serve and connect with their customer base. On the desktop version, a chat widget will appear on every website page as a small tab on side of the display. A click of the widget will open a chat window and the visitor can type in their question or comment. Site visitors using mobile devices are afforded the same functionality.

Steve Collins, the Miller Energy website designer at CMS4i, commented on MEI's increased level of connectivity..
"The chat implementation at Miller Energy is notable because it connects customers directly with technically qualified employees that are part of the day to day company operations. Customers will be communicating with real “hands on” engineers and specialists familiar with process measurement and control, and engaged in the field on a daily basis."
Look for the chat function on the Miller Energy website in early February. Use it to get fast answers to your questions from knowledgeable and engaged industry professionals.

Pressure Relief Valve - Guardian of the Vessel

Gas fired industrial boiler
Pressure relief valves protect this industrial boiler
from conditions beyond maximum allowable working pressure
Danger and hazards are an integral part of industrial processes. The mitigation of these dangers and hazards, as well as reducing the probability of their occurrence, is the primary charge of industrial process engineering. Every product intended for use in a process control setting has safety and protection included in its design criteria. Pressure relief valves fall in that category of products designed and intended solely for safety purposes.

Manufacturers of what most generally refer to as pressure relief valves break the genre down into two distinct groups, relief valves and safety valves. One manufacturer, Anderson Greenwood (a Pentair brand), distinguishes the two valve types in their "Pentair Pressure Relief Valve Engineering Handbook"...
Relief Valve: A pressure relief valve characterized by gradual opening or closing generally proportional to the increase or decrease in pressure. It is normally used for incompressible fluids.
Safety Valve: A pressure relief valve characterized by rapid opening or closing and normally used to relieve compressible fluids.
The difference between the two valve types is found in their response to an excessive pressure condition. The relief valve, according to the definition, responds proportionally to the pressure increase, whereas the safety valve provides a non-proportional rapid response. Note also that the relief valve is generally intended for use with liquids (incompressible) and safety valves are commonly applied to compressible fluids, which would include steam and air.

Pressure relief valves are found anywhere pressure is contained, be it a piping system, vessel, even a
household pressure cooker. The purpose of the relief or safety valve is to protect a pressurized system or vessel, should the system pressure exceed the maximum allowable working pressure. Simply put, keep it from breaking apart.

Because of the potentially catastrophic nature of a pressurized system failure, there is a high level of scrutiny, regulation, and testing focused on pressure relief and safety valves. The proper sizing and selection of the valves is also critical to providing proper function.

I have included a product bulletin from Anderson Greenwood with this article. Browse through it. It provides solid technical information, along with some excellent cutaway illustrations showing how the valves function. You are bound to discover something you did not know about safety and relief valves and their proper application. You can also contact the specialists at Miller Energy for assistance in proper valve sizing and selection.
