HC Flow Meter Installation

Installing an HC flow meter is an essential step in ensuring the accurate and efficient operation of your irrigation system. This section will guide you through the process of installing, programming, and maintaining your HC flow meter.
Preparing for Installation
Before installing the HC flow meter, make sure you have the necessary tools and equipment. You will need a pipe cutter, Teflon tape, and a wrench. It’s also important to review the owner’s manual to familiarize yourself with the installation process.
Installing the HC Flow Meter
- Turn off the main water supply to your irrigation system.
- Locate the section of pipe where you want to install the flow meter. The flow meter should be installed downstream from the master valve and upstream from the zone valves.
- Cut the pipe using a pipe cutter and remove any burrs or debris.
- Wrap Teflon tape around the threads of the flow meter and attach it to the pipe using union fittings. Make sure the flow arrow on the flow meter is pointing in the direction of water flow.
- Tighten the fittings using a wrench, but be careful not to over tighten as this could damage the flow meter.
- Turn the main water supply back on and check for leaks.
Programming the HC Flow Meter

Once the HC flow meter is installed, it’s important to program it to accurately track your irrigation system’s water usage. Follow these steps to program your HC flow meter:
- Access the HC controller’s settings menu and select the “Flow Meter” option.
- Enter the flow meter’s pre-calibrated K-factor, which is printed on the flow meter’s label.
- Set the minimum and maximum recommended flow rates for your irrigation system. These values can be found in the owner’s manual or on the flow meter’s label.
- Set the maximum flow rate for your irrigation system. This value should be lower than the maximum recommended flow rate to prevent damage to the flow meter.
- Set the daily flow totals reset time to coincide with the end of your irrigation cycle.
- Enable the leak detector and set the unscheduled flow conditions alert threshold.
Monitoring and Maintenance
Regular monitoring and maintenance of your HC flow meter is essential to ensure accurate water budgeting and prevent leaks. Here are some tips for monitoring and maintaining your HC flow meter:
- Check the analog dial reading on the flow meter regularly to track your total system water use and individual station water use.
- Use the HC controller’s flow reports to track your water usage and identify any abnormalities.
- Clean the flow meter’s sensing area and shielded 18 AWG wire regularly to prevent debris buildup.
- Replace the flow meter’s 3 AA batteries annually to ensure accurate readings.
- Remove the flow meter and store it indoors during winterization to prevent damage from freezing temperatures.
In conclusion, installing an HC flow meter is an easy and effective way to accurately track your irrigation system’s water usage and prevent leaks. By following these installation, programming, and maintenance tips, you can ensure the reliable operation of your irrigation system for years to come.
HC Flow Meter Models

When it comes to the HC Flow Meter, there are four different models available: HC-075-Flow, HC-100-Flow, HC-150-Flow, and HC-200-Flow. Each model is designed to work with a specific pipe size, so it’s important to choose the right one for your irrigation system.
HC-075-Flow
The HC-075-Flow model is designed to work with 3/4-inch pipes. It can measure flow rates between 0.2 and 15 gallons per minute (GPM). This model is ideal for smaller residential irrigation systems.
HC-100-Flow
The HC-100-Flow model is designed to work with 1-inch pipes. It can measure flow rates between 0.5 and 30 GPM. This model is suitable for larger residential or light commercial irrigation systems.
HC-150-Flow
The HC-150-Flow model is designed to work with 1.5-inch pipes. It can measure flow rates between 2 and 90 GPM. This model is ideal for larger commercial irrigation systems.
HC-200-Flow
The HC-200-Flow model is designed to work with 2-inch pipes. It can measure flow rates between 3 and 120 GPM. This model is suitable for very large commercial irrigation systems.
When choosing a model, it’s important to consider the size of your irrigation system and the flow rate you need to measure. Choosing the right model will ensure that you get accurate readings and that your system operates efficiently.
It’s also worth noting that all HC Flow Meters must be installed horizontally with the dial facing upward. The flow meter body has a marking indicating the direction of water flow, and installation must be in the correct orientation with water flowing in the direction of the arrow on the flow meter body.
In summary, the HC Flow Meter comes in four different models, each designed to work with a specific pipe size and measure different flow rates. Make sure to choose the right model for your irrigation system to ensure accurate readings and efficient operation.
