Role of automatic water level controllers in energy and water savings

Automatic water level controllers help maintain water levels in a tank within desired range. These devices consist of several components, including sensors, a control unit, and a valve or pump. In this blog, we discuss the importance of installing automatic water level controllers and their benefits.

How does an automatic water level controller work?

Automatic water level controllers use sensors to detect the water level in a tank or reservoir. These sensors can be multi-point, to define a range of low and high water levels in the tank. When the water level falls below a certain level, the control unit activates the pump or valve. Thus, water automatically starts flowing into the tank. Once the water level reaches the upper sensor, the control unit shuts down the pump and stops the water flow.

Advantages of automatic water level controllers

Introduced in the early 90's, the first electric water controllers were used in boilers, cooling towers, and waste water tanks. But those initial units had some flaws which required troubleshooting. Modern water level controllers have been perfected over time and have become more reliable. Global brands like Lauritz Knudsen (Formerly L&T Switchgear) are able to improve their products with access to various markets and test conditions.

Here are the advantages of using automatic water level controllers:

1. Power Savings: Automatic pump start stop helps in saving electricity consumption. It then translates to monetary savings for your farm or business.
2. Water Savings: By limiting water overflow, a water level controller also limits water wastage. This further improves your resource usage and results in cost savings.
3. Optimal Resource Utilisation: Generally water use increases during mid-day and reduces during night. A water level controller ensures 24x7 availability of water for your irrigation or commercial systems.
4. Automated Operation: Minimises the manual effort required for monitoring pump timer switches. You can focus on more productive tasks by installing an automatic water level controller.
5. Easy Installation with LED Monitors: The latest solid-state electronic designs with integrated LEDs are easy to install and monitor. For example, Lauritz Knudsen (Formerly L&T Switchgear) offers comprehensive support for installation and after sales service. Moreover, LED lights allow operators to visually scan the controller to verify proper operation.

Things to remember

Like all outdoor products, automatic water level controllers too have certain limitations. Here are some things to remember for installation and maintenance of your electric water level controller.

• Certain parts such as the level control sensors may require periodic service or replacement.
• Prolonged use can also cause rusting, fouling or deterioration in some components. Cleaning the devices periodically helps expand their lifecycle.
• Buying locally assembled water level controllers can often leave you without proper after sales support and warranty service. Hence proving costlier in the longer run.

Application / Uses of Water Level Controllers

Automatic water level controllers are widely used in,

1. Irrigation water tanks
2. Industrial water tanks
3. Stream level monitoring
4. Sewage pump level control
5. Overhead tank water level control
6. Cooling tower water level control
7. Remote liquid monitoring
8. Pool water level control

How to pick and choose the best Water Level Controller?

The first and foremost thing to do is to select a reputed brand for all your pump starter and controller requirements. This step alone will help save a lot of hassle and headache later on.

Here are some things to consider when finalising an automatic water level controller device for your setup:

• Accuracy: The sensor system should be advanced enough to gauge water levels with minimal deviation from the threshold accuracy.
• Integration: The system should be compatible with your existing irrigation or industrial setup. Look for water level controllers that support dry contact circuitry.
• Latest Design: With innovation in technology, always go for the latest design of water level controllers. Products offering solid-state components and LED indicators are the latest and greatest among all water level controllers.
• Tech Support: The brand you choose should offer extensive tech support during the purchase and installation phase.
• Warranty Cover: All major parts and components of the water level controllers should be covered under warranty.
