History of Water Level Sensors

Water level sensors have a long history dating back to ancient times when simple devices were used to measure water levels for irrigation and flood control. Over the centuries, advancements in technology have led to the development of more sophisticated water level sensing devices for various applications. Here’s a brief overview of the history of water level sensors:

  1. Ancient Water Level Measurement: The earliest water level measurement devices were simple float-based mechanisms used by ancient civilizations for irrigation and flood control. These devices typically consisted of a float attached to a lever or rod, which would rise and fall with the water level, indicating the depth.
  2. Early Mechanical Water Level Gauges: In the 17th and 18th centuries, mechanical water level gauges were developed for use in wells, reservoirs, and other water storage systems. These gauges often used a float connected to a chain or pulley system to measure the water level.
  3. Development of Electrical Sensors: The invention of electrical conductivity and capacitance sensors in the 19th century paved the way for more accurate and reliable water level measurement devices. These sensors could detect changes in water level by measuring changes in electrical properties such as conductivity or capacitance.
  4. Ultrasonic and Radar Sensors: In the mid-20th century, ultrasonic and radar-based water level sensors were developed, offering non-contact measurement capabilities. These sensors emit sound or radio waves that bounce off the water surface and are then detected to determine the water level.
  5. Pressure Transducers: Pressure transducers, which measure water level based on the pressure exerted by the water column, were also developed in the 20th century. These sensors are commonly used in applications such as groundwater monitoring, sewage systems, and industrial tanks.
  6. Modern Sensor Technologies: In recent decades, advancements in microelectronics and sensor technologies have led to the development of highly accurate and versatile water level sensors. These sensors often use a combination of different measurement principles, such as ultrasonic, pressure, capacitance, or optical sensing, to provide precise and reliable water level measurements in various environments.
  7. Wireless and IoT Integration: With the rise of wireless communication and Internet of Things (IoT) technologies, water level sensors can now be easily integrated into remote monitoring and control systems. These systems allow for real-time monitoring of water levels and automated alerts or actions based on predefined thresholds.

Today, water level sensors are widely used in various applications, including environmental monitoring, flood warning systems, water resource management, wastewater treatment, agriculture, aquaculture, and industrial process control. Continued advancements in sensor technology are expected to further enhance the accuracy, reliability, and functionality of water level sensing devices in the future.

Our level sensors and controls aren’t just for use in residential potable water holding tanks; some of the other applications include cooling towers, sump pumps, wastewater, boilers, water storage tanks, and building fire protection water tanks.

Types of Sump Pumps and Switches

Sump pumps and their trusty companions, the switches, work together to keep your basement or crawl space safe from watery woes. Read on to learn more!

Sump Pump Types:

  • Submersible Pumps: These workhorses live and breathe underwater! They sit in the sump pit directly, using an electric motor to power an impeller that forces water out through a discharge pipe. Submersibles are efficient, quiet, and ideal for most residential applications.
  • Pedestal Pumps: These prefer dry land! The motor sits atop a pedestal outside the sump pit, connected to the pump impeller by a long shaft. Pedestal pumps are less prone to clogging but can be louder and take up more space.

Sump Pump Switch Types:

  • Tethered Float Switches: The classic! A buoyant float attached to the pump by a tether rises with the water level, eventually pulling a lever or activating a micro-switch to turn on the pump. Simple and reliable, but prone to snags and require space for the tether’s movement.
  • Vertical Float Switches: These sleek operators use a rod and float mechanism directly within the sump pit. As the water rises, the rod pushes against a lever to activate the switch. More accurate and discreet than tethered floats, but may require specific sump pit dimensions.
  • Diaphragm Switches: These pressure-sensitive marvels utilize a diaphragm that flexes with rising water, pushing against a switch internally. No moving parts in the water, making them clog-resistant and suitable for dirty or sandy water.
  • Electronic Switches: High-tech heroes for the sump pump world! These rely on sensors like pressure sensors or ultrasonic sensors to detect water level changes and activate the pump. Offer precise control and advanced features, but can be pricier and require proper installation.

Choosing the Right Combination:

The ideal duo for your sump pump system depends on your needs and preferences. Consider factors like:

  • Sump pit dimensions and configuration.
  • Water level fluctuation and expected debris levels.
  • Desired noise level and budget.
  • Need for advanced features like automatic backup or alarm systems.

Consulting a qualified plumber or sump pump specialist can help you choose the perfect sump pump and switch combination for your specific situation, ensuring a dry and worry-free basement for years to come

Selecting The Right Sump Pump

Sump Pump Float Work

Pumps vary widely in quality. Pumps are used in a variety of applications, such as chemical vats, fuel depots, and swimming pools, but each one may present a different set of difficulties. The U.S. Department of Energy suggests the following factors to think about when choosing a pump:

Fluid: Pumps that weren’t designed for the job can be destroyed by chemicals and fuels. Select a pump that is made to handle the fluid’s corrosiveness and consistency to prevent degradation or clogging from slurry or debris. Similar to this, be aware of the fluid’s viscosity to make sure the pump has sufficient force to draw the liquid through.

Calculate the desired flow rate by dividing the total volume by the desired transit time for the liquid. For instance, if a 500-gallon pond requires full circulation once every hour, you should choose a pump with a 500 GPH minimum rated flow rate (gallon per hour).

Although pumps can function in a wide range of temperatures, if you are working with liquids that are hotter than 200°F, make sure the pump is rated for the highest liquid temperature you will be pumping.

Vapor pressure: The force per unit area that a fluid exerts when changing from a liquid to a vapor is known as vapor pressure, and it can be used to reduce the risk of cavitation by making sure the pump is rated for it.

Choosing a Pump from a Variety of Types

You can start comparing your options for pumps once you know the materials they must handle and the capabilities they need. The most typical pump designs and operating principles available today are listed below:

Centrifugal pumps: A centrifugal pump draws fluid into one or more impellers, such as a paddle wheel or propeller, to maintain a steady flow of a large volume of fluid at high speed. It can be used to pump a variety of low viscosity liquids, including those containing solid components like wastewater, and is one of the most popular pumping systems. A wide range of industries, including agriculture, water utilities, industry, power generation, petroleum, mining, and more, use centrifugal pumps.

Diaphragm pumps: Also called membrane pumps, a diaphragm pump is a device that moves fluid by a series of diaphragms moving back and forth. In a cycle, fluid is forced out of one chamber as it enters the other. These pumps are useful for pumping liquids with high solid content or high viscosity, such as chemicals, paints, or syrups, because there are no moving parts within the diaphragm chambers themselves.

Pumps that circulate fluids within a system are used instead of pumps that move liquid from one location to another. In order to ensure that the hot water is evenly distributed with the incoming cold water and to maintain a constant temperature, circulating pumps are frequently used in water heating systems. A circulating pump can also be used to evenly distribute chemicals that have been mixed into a container or to move water around a pond to oxygenate the water.

Pumps for moving oil, fuel, and other materials from one container to another, such as transferring fuel from a tank into large machinery, are known as fuel and oil transfer pumps. Oil transfer pumps are made for use with high viscosity fluids and are toughly constructed for higher flow rates.

Pumps for chemicals: Chemical pumps are made specifically for the creation, use, and disposal of chemicals. They are constructed of corrosion-resistant materials like glass, rubber, plastic, rubberized steel, titanium, and stainless steel. Use a pump made specifically for the chemical you want to pump because different chemicals have different corrosive effects on materials.

Drum pumps: These pumps are designed to help you suction out fluids from drums, barrels, pails, and totes to reduce the risk of spills when pouring the container or to draw fluids out of a heavy container. Hand-powered pumps are useful for low-volume or remote pumping applications where electricity is not available, whereas electric-powered pumps are useful for tasks requiring high volume transfer. A pneumatic pump that runs on compressed air is a good choice if you need higher flow rates than a hand-powered pump and more precise flow control than an electric drum pump without electricity.

Sump pumps are set off automatically once the water level in the sump pit gets to a predetermined height. A homeowner can calibrate the pump to start at any depth they wish by adjusting the float device of the sump pump.

Water runoff and/ or seeping water is collected inside the sum pit. As the water gathers, a float rises as the water level rises. The float has control of an on/ off switch for the pump. Once the float rises to a predetermined height, the pump turns on. The pump continues to function until the float falls low enough to disconnect the switch. The pump is inactive once more until the water level increases again.

Types of Sump Pump Floats

Different types of floats are used by different types of sump pumps. Pedestal pumps will typically have a bulb type float connected to a metal rod that turns on the pump motor’s switch. Other types of pumps utilize floats attached to arms that will raise and lower as the water level rises and lowers. A tethered float is a float that is attached to the pump utilizing a tethering mechanism.

Old Sump Pump Float Working Principle

When the water level rises, the float will rise too. As the float rises the tether steadily releases. The tether is predetermined to start the pump when a specific amount of tether gets released. When the water levels lower, the tether becomes loose and the float falls back to its starting position.

New Sump Pump Float Working Principle

Float switches and water level controls typically start out open, meaning there are no alarms that are required to be activated since the water level is at its lowest.

  1. When the cooling tower stops using the water for its industrial operations, the water level starts to rise. No alarms have been activated up to this point.
  2. When the water level reaches the probes, a signal is transferred between the probes informing the high alarm to activate.
  3. When the high alarm is activated it can be programmed to tell the fill to stop filling up the water.
  4. Finally, when the water reached the predetermined limit, the fill stop kicks in and the process starts all over again.

With correct maintenance, your cooling tower float switches could last for years of operating. A lot of float switch failures typically occur due to degrading, wearing out, or fouling. Cooling tower coatings can safeguard the storage tanks, but what is safeguarding the float switches? Our water level controls can replace your old float switches once and for all and won’t degrade, wear out, or foul, because of any water quality.
