How to Properly Install and Maintain Hunter Flow Sensor in Your Landscape

Hunter Industries is a well-known name in the world of irrigation systems, and their flow sensors are a crucial component for ensuring efficient water usage in your landscape. Proper installation and maintenance of these sensors are essential to maximize their effectiveness and prolong their lifespan.

When it comes to installing a Hunter flow sensor, there are a few key steps to keep in mind. First and foremost, it is important to choose the right location for the sensor. Ideally, the sensor should be installed downstream from the main shut-off valve and before any zone valves. This will allow the sensor to accurately measure the flow of water through the system.

Once you have selected the location for the sensor, the next step is to connect it to the irrigation system. This can typically be done by cutting into the mainline and inserting the sensor in-line with the pipe. Be sure to follow the manufacturer’s instructions for proper installation, as this will ensure that the sensor functions correctly.

After the sensor has been installed, it is important to calibrate it to ensure accurate readings. This can usually be done through the irrigation controller, where you can input the sensor’s specifications and adjust the settings as needed. Regular calibration is essential to maintain the accuracy of the sensor and prevent any issues with over or under-watering.


In addition to proper installation, regular maintenance of the Hunter flow sensor is also crucial. This includes checking the sensor for any signs of damage or wear, as well as cleaning it regularly to prevent clogs or blockages. It is also important to check the sensor’s connections and wiring to ensure that everything is secure and functioning properly.

One of the most common issues with flow sensors is debris buildup, which can interfere with the sensor’s ability to accurately measure water flow. To prevent this, it is recommended to install a filter before the sensor to catch any debris before it reaches the sensor. Regularly cleaning the filter and removing any debris will help to maintain the sensor’s accuracy and prolong its lifespan.

Another important aspect of maintaining a Hunter flow sensor is to regularly check for leaks or other issues with the irrigation system. Any leaks or malfunctions can affect the sensor’s readings and lead to inefficient water usage. By staying on top of any maintenance issues and addressing them promptly, you can ensure that your flow sensor continues to function properly and help you save water and money in the long run.

In conclusion, proper installation and maintenance of a Hunter flow sensor are essential for ensuring efficient water usage in your landscape. By following the manufacturer’s instructions for installation, calibrating the sensor regularly, and staying on top of maintenance tasks, you can maximize the effectiveness of the sensor and prolong its lifespan. With a well-maintained flow sensor, you can enjoy a healthy and beautiful landscape while conserving water and saving money on your water bill.
