Tesla’s success with battery-powered electric vehicles (EV’s) has drawn the public’s eye away from Fuel Cell Vehicles (FCV’s). However, manufacturers like Toyota continue to invest in the FCV technology. Toyota has invested in FCV’s, so what do they know about FCV’s, and what’s holding back other manufacturers from using the technology?
Hydrogen production is a global industry, and it’s a growing one. Hydrogen is used in many manufacturing industries and also as an energy storage medium. There are several methods of producing hydrogen but distribution is expensive. Many hydrogen users opt for on-site generation instead, and this is likely to increase as hydrogen begins to supplant gasoline and diesel.
Cryogenics is the science of dealing with the production of and effects of very low temperatures. However, there’s some debate over how low ‘low temperature’ must be to qualify as cryogenic. Some say lower than -1000C. Others, such as NIST, put it at below -1500C. At these temperatures most gases become liquid, which gives them some interesting uses. Cryogenic temperatures are mostly produced through the Joule-Thomson effect, which takes advantage of the relationship between pressure, temperature, and volume.
For an inert, nontoxic gas, nitrogen is surprisingly dangerous, especially when you consider it comprises 78% of the air we breathe. That’s a problem, because nitrogen is also extremely useful in many industrial situations. Nitrogen leaks are hard to detect, which is why it’s important to incorporate excess flow valves into systems using this gas. Here we’ll take a look at what makes nitrogen so useful, how it’s used, the consequences of leaks and how to protect against them.
Any liquid or gas leak is a problem, but especially so if it’s a corrosive, toxic or flammable fluid. Incorporating an excess flow valve, or EFV, into pipework improves safety by sealing off the flow should a pipe break or be disconnected.
Hospitals employ sophisticated equipment incorporating complex fluid handling and monitoring systems. This is because liquids and gases are used extensively to prepare devices and instruments for use, for cooling, heating, and for taking on essential bodily functions. Whenever fluids are pumped and filtered there’s a risk of leaks and blockage. Either will cause abnormal flows, and in the biomedical sector such failures can have serious consequences. Here’s an overview of four places where it’s important to know correct flow rates are being maintained.
The semiconductor market continues to grow, and it’s not just all those new smartphones. Cars and lighting are the other big drivers, and all this growth means continued investment in semiconductor fabrication facilities and equipment.
Sludge sounds unattractive, and indeed usually is. Defined as, “a muddy or slushy mass, deposit, or sediment,” it’s the kind of thick, viscous goo you’ll find at the bottom of a pond. The thought of activating it conjurors up images of some science-fiction blob slithering through your town or city.
That’s actually not too far from reality. While it’s probably not in your neighborhood, activated sludge may well be just outside your city limits. The good news is that it’s far from harmful. In fact it’s positively beneficial as it forms an essential component of many large-scale wastewater treatment systems.
Measuring fluid flow is difficult. To start with, there’s the question of whether to measure volume or mass. Then within each category there are multiple technologies to chose from. Cost rises with accuracy, and some high-precision methods lack robustness for industrial application, especially in large, distributed plant environments. That’s why, before committing to a flow measurement method, it’s important to step back and consider how the data will be used.
Our customers spread across a wide range of industries, but all depend on their ability to move liquids and gases through sophisticated equipment.
