Barometric Pressure

Barometric pressure has a direct effect on the life around us. The amount of atmospheric pressure is constantly changing and sudden changes can create health issues such as migraines in people to affecting behavior in animals. Barometric pressure is a highly searched criteria reaching around 201,000 times a month on average within the United States and achieving over 300,000 searches with the spelling of barometric pressure.

Barometric pressure measures the amount of downward force that the atmosphere exerts within a specific air column. Barometric pressure travels in terms of peaks, flats and valleys and will rise and fall accordingly. Atmospheric pressure is a key means to predicting weather 12 to 24 hours in advance and has a 70% accuracy rate. Pressure sensors will detect a drop in atmospheric pressure as inclement weather approaches. Typically, pressure drops in front of a weather system and then will rise as the weather systems moves out of the area. High pressure typically entails bright, blue, clear days or nights while normal pressure periods results in scattered clouds. As the atmospheric pressure gauge drops, expect increasing clouds and possibly storms as the atmospheric pressure continues to drop.

As people may feel the effects of barometric pressure changes in terms of ear pain, dizziness or headaches, animals too are affected by pressure changes. Many animals rely on scent and scent is highly dependent on atmospheric pressure. When low pressure is in the area, scent will travel further and higher in the atmosphere but as the millibars continues to drop resulting in rain, fog or snow, the scent will hug the ground and last longer. On high pressure days, scent will dissipate quickly.

The overall relationship between barometric pressure and changing weather conditions results in changes in animal behavior. Hunters and anglers alike monitor the sudden drops in millibars to predict an increase in animal movement. This increase in movement can be attributed to the animals or fish expecting inclement weather and survival instincts to feed and stock up on energy to survive a period of discomfort associated with long lasting storms.

Hunters, anglers and those sensitive to changes in barometric pressure may benefit from monitoring and tracking barometric pressure readings from gauges and at home weather stations. There are several types of pressure sensors and monitors that are available on the market. The prices range on eBay from a few dollars to hundreds of dollars for high end at home weather stations that come with a variety of external sensors for gauging wind direction, barometric pressure, temperature, and humidity. The barometric pressure sensor on many models tracks the past 24 hours of pressure readings that allow the user to determine if pressure is stable, rising or dropping at any given time. The following devices are popular for the climate monitoring enthusiast:

The Honeywell TE923 is a Deluxe Weather Station that cost from $200 to $300 from Amazon.com and utilizes external sensors such as the barometric pressure sensor, temperature and humidity sensors, UV sensor for measuring harmful UV levels and wind and rain sensors.

MFJ 196RC Deluxe Wireless Atomic Weather Station is offered on eBay for slightly below $200 and also utilizes external climate sensors for measuring and displaying barometric pressure changes, wind direction, temperature and humidity.

One of the downfalls of these types of home weather stations is the difficulty in storing these measurements. All of the monitors that I have seen across eBay and amazon display roughly the same information with the same graphics. While the Honeywell weather station stores 24 hours of atmospheric pressure readings, the MFJ weather station stores 12 to 20 hours of readings. From what I can tell, these popular models do not write each data point to an external system or within its memory for long term analysis. Don’t let that hold you back from exploring or purchasing one of these weather stations as the NOAA collects this types of data from across the country. I believe you can subscribe to their feed and bring in historical and current data for a specific area.

Industrial Pump Repair

Industrial pumps are devices that are used to move gases or liquids with the purpose of moving the fluid or gas by a physical or mechanical action. Many think that pumps create pressure but this is not correct. It is not the pump that causes the pressure; it is by adding resistance to any flow that causes pressure. In the industrial pump market there are several different types of pumps that are used and therefore might need to be repaired. When repairs are needed it is important to use companies that have certified technicians available.

One type of industrial pump is a hydromantic pump. This is a pump regularly used in water treatment. Many wastewater treatment centers use these to help them keep the water and environment cleaners. Because of the consequences that could be associated with a pump breaking down, most water treatment plants make sure their pumps are kept maintained and repaired to keep them running as efficiently as possible.

Positive displacement pumps are another example of industrial pumps that are used today. These pumps cause liquid to move by trapping a set amount of liquid then displacing the volume that is caught out into a discharge pipe. There can be many different types of this kind of pump. There might be rotary types like, screw pumps or shuttle block pumps or a liquid ring vacuum pump or even a Wendelkolben pump.

There is also what is classified as a dry pit submersible pump which is specifically used in applications where the pump can be left unattended and still be relied upon to work with high performance and that resist clogging. These pumps are used to pump sewage and are generally used in wastewater plants or industrial plants where solid materials are being pumped.

Businesses that have industrial pumps and motors cannot afford to have their machines broken for long periods of time. Repair companies have to be ready to step in on a minutes’ notice to help analyze the problem and come up with a repair. Repair companies understand that any downtime caused by a broken pump or motor cuts into company production and throws the company off schedule. Any industrial pump repair company will understand how critical the machines are to running the business. All repair companies will have qualified technicians able to work on most any working brand pump as well as expert customer service to help and follow up on any further needs.

A quality industrial pump repair shop should be able to provide expert service and guarantee their work 100% for any makes or model pump they repair. The repair shop that works on industrial pump repairs will probably be a complete Industrial Machine repair shop. This means that they will repair motors, pumps, gearboxes, and possible circuit board hydraulics repair. It’s possible they might also offer a full machine shop and panel shop for repairs to done in-house as well as preventive maintenance as in vibration analysis and calculating the condition of bearings in electric motors as well as checking that there is sufficient lubrication.

 

How to Monitor Tire Pressure

According to most of the mechanical engineers and trained mechanics, tire is considered to be the most critical part of the car. They monitor the driving of the car and are one of the most important factors as far as smooth driving is concerned. You need different types of tires if you are driving on ice as compared to what you will require while driving on rough surface. The inflation is very important. An over inflated tires as well as the under inflated tires can cause a lot of problem. Hence, it is quite important to monitor the tire pressure. They also harm the environment as they leads to lots of carbon monoxide emission from the car. Hence the tire pressure monitoring systems are used.

Up till now it is quite clear that we can monitor the tire pressure with the help of TPMS. However we also need to know that how much type of TPMS is there. But I would first like to talk about various techniques being used to monitor the tire pressure.

The first way is by using the pressure sensors. Suppose your car has four tires. Then you will require four pressure sensors. All of the pressure sensors are set to measure the real time pressure.

If any sensor shows that there is about 25% less air pressure than the normal cold tire inflation pressure then the driver will be informed and he will soon have to take some action so that this problem is solved completely.

There are one another way as well. In this method the air pressure is calculated. The velocity of each tire is also being calculated. If you have studied the physics in intermediate then you will certainly understand that what is the trick behind this method?

Suppose the velocity of one tire is found to be more as compared to the other tires. What does this mean? Actually if the tire will be underinflated then it will have to rotate more number of times to travel the same distance. Hence its velocity will be higher. This is the principle of these methods.

So these are the two ways through which you can calculate the tire pressure. The tire pressure monitoring system are developed using the above two principles. Generally there are two types of TPMS. They are the indirect and the direct one. You just get them installed in your car from some service station.
