What to Consider When Purchasing a Mass Flow Controller

A number of industries require the monitoring of gas control. Those industries, most commonly the semiconductor industry, are required to purchase equipment that is used to control and monitor the flow of one or multiple gases. Individuals or businesses in these industries are likely to purchase a wide variety of products including a mass flow controller.

With a large number of mass flow control product available there are a number of things that should be taken into consideration before a product is purchased. One of the most important things that must be considered is what the product offers. This information can most easily be determined by researching a number of mass flow controllers. When a product is purchased or being sold it is likely that there will be valuable information provided with the item. This information should be thoroughly read and examined to ensure that the best mass flow controller is purchased.

When reading a product guide or an instruction manual, one thing that should be looked at is the simplicity of the product. Many of the individuals responsible for using a mass flow controller are likely to be experienced and trained in the field; however, that does not mean that an easy to use product should not be purchased. The instruction manual is a great way to determine if a mass flow controller would be easy to use and operate.

The speed of a mass flow controller should also be examined. A product package or description should provided detailed information on how quickly results are shown. This information is important because it will not only save time, but money as well. Older models are likely to have a slower response time; therefore, individuals looking for a faster response are encouraged to look at newer mass flow controllers.

In addition to speed and product simplicity, it is also important to know how dependable the product is. This information may be difficult to determine through a product manual. To learn the dependability of a product or a manufacture individuals are encouraged to talk to others in similar industries or use the internet. This will allow you to get positive and negative feedback through those who many have previously owned or used a particular mass flow controller.

Another thing that should be examined before purchasing a mass controller is the cost of ownership. When examining the cost many individuals only concentrate on the purchase price, but there is more that is included in the cost of ownership. It is important to consider the cost of repairs or replacements if they are needed. These ownership costs could be eliminated if a dependable product is purchased. It is also important to determine the amount of power that a mass flow controller will use. Most mass flow controllers will operate on little power, but that does not mean that all will.

Taking all of the above mentioned points into consideration will help to ensure that a quality mass controller is purchased. With a small amount of time and research a bad purchase can be prevented.

Golf's Four Most Common Rules

golf doesn't have a lot of rules, but you should know them. That's why it's good to review the rules periodically. I don't devote a golf lesson or a longer golf instruction session to the rules, but I mention them during my golf lessons. That way the student learns the rules without detracting from his or her golf lesson.

Below we examine five common rules. Adhere to them whenever you play. Also, don't forget about local course rules. All clubs have rules covering specific course areas. If you're playing a course for the first time, check out these rules beforehand. They may save you a stroke or two in a sticky situation. If you're playing a course for the umpteenth time, refresh your memory as to the local rules. They may have changed.

1. Water Hazards Golf's rules define a water hazard as "any sea, lake, pond, river, ditch, surface draining ditch, or other open water course (whether or not containing water), and anything of a similar nature." Courses mark water hazards with yellow stakes and lines. But the rules don't stop there, as I mention in my golf tips, they also discuss a lateral water hazard.

The rules define a "later water hazard" as part of a water hazard "so situated that it is not possible, or is deemed by the committee to be impracticable, to drop a ball behind the water hazard according to rule 26-1b." In other words, it's a water hazard that doesn't lie between the tee and the green. The course marks these off by red stakes or lines.

If you hit into water you have four remedies:

1. Play the ball as near as possible to the spot from which the original ball was played.

2. Drop a ball behind the water hazard, keeping the point at which the ball entered the water's edge, directly behind the hole and the spot where the ball is dropped. There's no limit to how far back the ball may be dropped, as long as the point of crossing lies between the drop and the hole.

3. Play the ball as it lies in the water hazard.

4. If a ball goes into a lateral water hazard, drop a ball away from the hazard, but within two club lengths of the point from which the ball last crossed the water. However, the ball can't come to rest any closer to the hole than the point at which the first ball crossed the hazard.

2. Hang Time
You're on the 7th green and you hit what your think is a great put. The line is good. The speed is good. And the break is good. It's a done deal, you think. But the ball stops just at the lip of the cup. How long can you wait for the ball to drop into the cup. According to rule 16-2, you can wait the time it takes you to reach the hole plus 10 seconds. By the way, there's no penalty for allowing a ball stay in the cup and letting the next player's ball land on it.

3. White Stakes
You tee off on the 9th hole. You pull the ball left pass some white stakes. White stakes on a course indicate out-of-bounds. You have only one option under rule 27-the dreaded stroke and distance penalty. Add a stroke and drop a ball as close as possible to where you last played. To keep play moving when you might be OB, play a provisional ball under rule 27-2. Keep in mind that a wall or other boundary can also mark OB under local rules. That's why you need to check local rules.

4. Lost Ball
On the 15th you hit a drive just to the left of the fairway in deep rough. You look for the ball but can't find it. You declare a lost ball. After hitting, you discover your original ball. If you declared a lost ball and you hit a second ball, the provisions of rule 27 apply. Once the ball is declared lost and another ball played you can't play the original ball. However, what if the first ball went in the hole?

If the ball goes in the hole, the first ball would be counted, even if you hit a second ball. The first rule of golf states: The Game of golf consists of playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules. The key words here are "into the hole." Once the first ball when in the hole, the hole was over for the player. Once you've done that, your play of that hole is considered finished. You've completed play of a hole as soon as your ball finds the cup

These four rules come into play fairly frequently. They won't necessarily change your golf handicap or eliminate your need for golf lessons, but they are good to know to enhance your knowledge of the game and avoid getting others mad for not knowing them.
