An Introduction to Tools for a Propane Transfer

Propane Transfer | Flowmetrics

Propane is a commonly used fuel that is vital to many operations and industries. Typically, propane is stored in tanks designed specifically for the purpose of holding the fuel in its liquid state. Whenever a particular tank is low, you are often left with two choices: you can purchase a new, full tank or have an existing tank refilled. If you choose the former, all you need to do is make the purchase. If you decide on the latter course, then various propane transfer tools are required.

Oil and Gas Processing: How Gas Flow Measurement Affects Production

Oil and Gas Processing | Flowmetrics

While you might not give much thought to how oil and gas reaches your local fueling station unless prices begin to rise, the steps involved may surprise you. From drilling for crude oil to refining it for a number of uses, including the gasoline you pump into your vehicle’s fuel tank, much goes into this process. There are also a number of important factors involved in oil and gas processing; however, from the search for fossil fuel sources to the refinement of such products to measuring consistent flow rates at oil refineries and other fuel facilities, gas flow measurement is a key component of the manufacturing process.

How to Use a Batch Controller

Batch Controller | FlowmetricsA batch controller calculates the number of items or the volume of things that are being processed at any given time. If these are solid objects, they work in the form of counters to calculate individual things, but when it comes to gas or liquid, these batches need to be counted by other means. Liquids and gasses pass through tubes when they are transferred and the volume of material must be communicated in the form of velocity, such as through rate per minute. A flow meter deals with volume and the batch controller displays the amount of liquid and gas that is passing through the tanks to the tubes.

When looking for a batch controller, you may select one that accepts pulses per second and gives rates and total readings for batching functions. You should also see hardware and software features and clear monitoring that is accurate and easy to read. You could find a controller that can monitor remotely or up close and can print out results as needed.

A Guide to Ratemeters

A Guide to Ratemeters | Flowmetrics

Measuring flow requires that you have adequate means for reading information. Ratemeters and totalizers offer a user the ability to understand exactly what is happening within the mechanisms of flow metrics. Without these handy gadgets, measurement is far more difficult. It is important not to rush through this facet of flow measurement, as you might find that there are a number of variables to consider when choosing a ratemeter and totalizer. In the following, you will read about several different kinds of ratemeters.

 

The MINITROL

912-MRTThe 912-MRT, otherwise known as the MINITROL, is a ratemeter with six digits and a two level, five digit preset alarm control. There are two inputs, A and B, which can be calibrated in three different ways:

  • “A” subtract “B”
  • “A” add “B”
  • “A” and “B” as separate totalizers

Moreover, the MINITROL can handle a whopping 10,000 pulses per second. With five digits and a floating decimal, you can measure in true blue engineering units with the rate set in terms of seconds, minutes or hours. You can also toggle between the current rate and total without disrupting the count. This ratemeter is perfect for all kinds of flow measuring fun.

 

918-RTP

918-RTPIf you are searching for something a little more futuristic, you might want to look into the 918-RTP, which boasts a 2 X 16 backlit LCD display with a ratemeter and totalizer that you can preset by way of two pulse inputs. You can even connect this piece of equipment to a network for data acquisition. Like the MINITROL, the 918-RTP has two inputs (A and B), each of which can define up to 16 points of K-factors. What does this mean? Well, simply put, this allows for a greater degree of accuracy, which makes this ratemeter worthy of consideration for future purchase.

 

 

The KEPTROL

920-KRT8The 920-KRT8, known as the KEPTROL, is a serious meter allowing for 20,000 pulses per second. It is faced with a .55” screen that displays both numbers and letters. With a 16 point K-Factor this unit can give majorly accurate readings. Perhaps the most wondrous attribute of this ratemeter is its capacity to transmit data to remote totalizers, computers, programmable controllers and many other kinds of digital data storage devices. To top it all off, the KEPTROL offers you the ability to protect your information with a password. This can be useful if you are storing your equipment in a place that is accessible by other people or if the measurements belong to patented research that you want to keep away from the vying hands of competitors.

You might find that there are a lot of overlapping features, such as two programmable inputs, toggling capabilities, security features and alarms. Because of these shared features, it would be advisable to seek out an expert to help guide you through the tedious work of researching the many kinds of ratemeters. He or she can help you determine what you actually need. After all, an LCD screen might look sleek, but upon closer examination you might discover that it is actually superfluous.

 

PID Controls

PID Controls | Flowmetrics

PID control stands for proportional, integral, and derivative control. This type of process management is used to maintain set parameters, and works well for temperature or motion. All three portions of this control setup manage whatever parameter you desire in different manners.

Proportional control controls how far the measured parameter is from the set parameter. In terms of temperature it will tell you how far off from ideal the process is running; i.e. +1.85 °F or -.07°F. Managing the process with proportional controls alone will work, but the systems will swing between over- and under- correcting.

Integral controls are added onto proportional controls to factor in timing into the setup. By measuring the time between measurements of the parameter the system can determine the speed at which the motion or temperature are changing; i.e. -.1 °F/second. By knowing this measurement the system can then account for this with more precision, cutting down the amount of over-correcting. Still this combination will need one final layer to appropriately maintain the parameter dynamically.

Derivative control measures the acceleration of the parameter, in effect the speed at which the speed is changing. With this level of control, the parameter changes can be dampened and returned to the set point reliably. In terms of motion parameters, with a properly installed PID control system a ball bearing can be kept from rolling off a glass plate even when pushed by people.

Capturing Phase Transitions at Atomic Level

Capturing Phase Transitions at Atomic Level | Flowmetrics

Engineers from the University of Pittsburgh have used a Dynamic Transmission Electron Microscope to view the phase changes in aluminum alloys. The scale at which the observations are made can pin-point atoms as the materials go from solid to liquid and liquid to gas under different environmental situations. Data garnered by the engineering team will help better model the properties of these alloys for manufacturers and engineered material designers. 

Prior to the advent of the DTEM, we could only simulate these transformations on a computer. We hope to discover the mechanisms of how alloy microstructures evolve during solidification after laser melting by direct and locally resolved observation.

Better Biofuels

Better Biofuels | Flowmetrics

Engineered bacteria is beginning to streamline biofuel productions. The bacteria being used is a strain of E. coli that has been adapted to withstand liquid salt solutions used for breaking down plant matter into sugars. As these cells adapt better to this type of environment, biofuel processing will no longer need to remove the liquid salts from the mixture before introducing the bacteria, the process would be a “one pot method.”

Yields are currently significantly lower as the tests are using less pure sugar than other processes. Further refining of the E. coli strain will hopefully boost the returns seen from this vastly easier method.

Currently, we have only engineered the strain to digest cellulose so it can use the resulting glucose to grow and make the biofuel,” explains Mukhopadhyay. “We can also engineer it to digest hemicellulose, another large component of plant biomass so that it can use the resulting xylose for growth and production also!”
