Liquid Level Sensors & A/C: Tips to Beat Summer Cooling Expenses

Summer heat is one of the hardest conditions to endure. Both from the standpoint of humidity and uncomfortable working conditions to being unable to feel comfortable in ones living space. Then there’s also the added dangers of spoilage and machine breakdown caused by extreme temps.

As a result, it’s important that A/C and other cooling equipment are used to maintain appropriate temperatures at these locations. Achieving this is dependent on the conditions and area needing to be cooled and will require  A/C systems that continually work hard.

The A/C is able to a cool space through the use of chemicals like refrigerant (Freon) by converting gas to liquid and back again.

Maintaining these systems in commercial and residential settings is important. Breakdown poses a cost risk in addition to adverse health risks from the heat. Ensuring that the compressor, the condenser, and the evaporator are all working properly is important.

Not to mention, Freon is expensive. Wasting large amounts can result in hefty cooling costs. To ensure its staying put, a method to measure the presence or absence of the liquid is important.

Enter the liquid level sensor.

Loading a Boat

Don’t Risk Boat and Off Road Vehicle Shutoff, Use Liquid Level Sensors

As warm weather makes its way to more parts of the country, there will be an increase in the use of boats and off road vehicles. Whether you seek outdoor adventures for a weekend pastime or depend on boating and off-road vehicles to perform job related tasks, keeping these vehicles up and running is important.

In this post we’ll discuss one possible issue with low oil levels and how a liquid level switch can be the perfect solution.

The Problem:

Getting an accurate oil level read in your boat or ATV’s tank could lead to engine failure, shut-off, being stranded and other breakage. The old fashioned dip stick is good for a quick rough estimate, but it’s not accurate to give you a fair warning that fluids are running out.

The Solution:

If the OEM had integrated a liquid level oil sensor into their design, it would be possible to get a more accurate measurement and a much more advanced notice of a potential engine failure due to low lubricant.

How Liquid Level Sensors Work

Liquid level sensors are the most accurate and reliable way to measure oil tank levels. These sensors can automatically sense the levels of the liquid in the tank and then electronically communicate that reading to you.

These readings offer precise levels to warn about low level, high level and overflow of oil in the tank to ensure safe and efficient operations while keeping the motor moving and keeping you working efficiently.

Liquid level sensors for tank level monitoring, fuel and chemical injection and other applications have all been crucial to the continued advancement of the oil and gas industry in every step of the processes they require.

Level Sensors Make Portable Power Reliable

Schools will be out for summer break soon and temps are warming up for most of the nation. While it may mean poolside relaxing and vacations for some, for many who work in the construction and maintenance industry, busy season is just getting started.

To help keep these sites up and running, many rely on portable power units that deliver necessary electricity and cooling.

Generators and portable air units make it possible to continue working for the duration of the project and are an important, hardworking element of the job. These offerings can be purchased or rented for use during temporary, emergency and permanent applications. Regardless of what they will be used for, their reliability is of extreme importance.

How can they ensure continued performance?  With level sensors.

How Level Sensors are used in Portable Power Equipment

For temporary power needs, generators are a top choice at commercial sites. To keep them running, fuel must be present in the system. With a level sensor it’s possible to monitor fuel levels so there is no risk of power loss or shut off. In emergency situations and where power loss would be detrimental to operations, this monitoring is especially critical.

Loss of fuel for portable equipment also translates to money lost for businesses. Employee downtime, temperature issues and even recharge costs can also all create problems.

Instead, a reliable level sensor can measure the presence of fluid (in this case fuel) inside of the tank to assist in keeping the power equipment functional.

Depending on an applications needs, single point, multi-point or continuous monitoring level sensors can be used.

For oil & gas, an ultrasonic liquid level sensor is typically be used. These sensors emit pulses of sound at the liquid surface and record and calculate the time it took for the sound wave to bounce back. The lower the liquid level, the farther the sound travels and the longer the process takes.

Liquid Level Sensors Help Farmers with Crops, Decrease Food Waste

The agricultural industry is faced with many hurdles today. From changing weather patterns, to limited budgets, stringent guidelines as well as logistical and financial challenges, there is so much that goes into the food that ends up on our dinner plates.

One area where farmers must improve to start turning things around is related to the crops they produce. Better maintenance, greater productivity and less waste is critical.

Better Crop Maintenance

In some of the most important farming areas in the nation, the threat for drought has already created a stir around summer crop planting this year. Farms are having to make decisions about water use and soil monitoring so they can ensure necessary growth yields are met.

The need for more irrigation also increases spending and leaves less room for profits. To help curb this, tools that measure soil moisture and precipitation levels become critical for farmers. The continued quality control they provide– regardless of drought, supports growth throughout the season and for farmers, that’s a win-win.

Fluid switches and liquid level sensors find application within these tools. The sensors provide accurate measure of water being delivered to the plants and can sense how much is left for the soil to absorb.

Over watering can have just as bad an effect on crops, causing rot and not to mention, wasting water – which is both costly and bad for the environment.

Curbing Food Waste

Better crop yields also lead to less food waste – another threat we’re faced with today.

Waste in the form of less than perfect crops, deformed vegetables and those with abrasions getting left behind is part of the problem. Up to 20 billion pounds of produce are being left out in the fields and it’s happening on a grand scale.

That number is only part of the problem. When these crops make it to our dinner tables, even greater waste happens.

According to a research from the USDA, “30 million acres of cropland, 4.2 trillion gallons of irrigation water, 1.8 billion pounds of nitrogen fertilizer, and 780 million pounds of pesticides went into producing food that was thrown away.”

With tools to measure and maintain what’s being delivered to crops, it’s possible to create a better yield that farmers can sell. This type of precision agriculture is exactly what’s needed to curb food waste.

Solving Crop Insurance Woes

Finally, crop insurance is a giant industry. These policies help farmers to manage the risks they face due to Mother Nature and unpredictable weather changes. Without insurance, farmers risk the possibility of being shut down if a disaster occurs, but purchasing it is also costly.

With better tools in place to monitor the environment in a field, farmers can lessen the impact of weather extremes. Sensors that measure water provide data, monitor conditions and activate irrigation systems when needed. Together this helps to improve the landscape for today’s already burdened farming industry.

If you’re looking for a float switch or liquid level sensor, SMD Fluid Controls has a variety to choose from and can even build custom applications. Contact us today and we’ll help you find the best sensor for your project.

Clean in Place: Keeping the Dairy Industry Sanitary

The dairy industry is a vital part of the global food system. Milk provides necessary nutrients to families and many of its byproducts are the key component in a balanced diet.

In a large scale production setting, there are not only strict guidelines when it comes to storage, collection and pasteurization of milk from cows, but farmers must also utilize new technologies and innovations to keep up with demands.

Chief among these needs is the assurance that sanitation is happening and that products are safe for human consumption.  Working closely with the Food and Drug Administration (FDA), the industry has maintained their status as one of the most hygienic practices in the nation.

Safety in Food Production

Today, milking cows has become an exact science for farmers. To yield the best results, they are closely monitoring and testing from the milking process all the way through to the production. Much of this monitoring checks for quality and aims to prevent diseases transmitted by food.

A large part of this prevention comes from properly washing equipment used in the production process.  A system known as Clean in Place (CIP) is critical for the dairy industry as it makes quick, proper cleanings of the interior of vessels, tanks and lines, possible.

Clean in Place (CIP) for Dairy Farming

CIP systems are commonly used in manufacturing settings, especially in dairy production, as they are the only way to assuredly clean and sanitize equipment used in food production.

Equipment with sensors that accurately measure and sense liquid presence or absence are essential to the continued success of the dairy industry.

These systems use water, heat and/or chemicals to clean and sanitize and remove dirt, spores and other bacteria, both visible and not visible, to guarantee cleanliness. Fluid presence in tanks as well as their levels and temperatures are also measured to ensure proper cleaning and sanitation per stringent industry guidelines.

Through the use of accurate sensors, the system also eliminates the need to dismantle equipment each time and speeds up production times without putting health at risk.
