While a smart sprinkler controller manages your watering schedule, it cannot see a cracked pipe underground. The Hunter HC Flow Meter integrates with your Wi-Fi controller to monitor water volume down to the gallon. If a pipe bursts or a zone leaks, it automatically triggers a system shutdown and texts your phone—preventing flooded properties and massive water bills in the greater Charleston area.
Imagine this scenario: an underground PVC pipe in your irrigation system cracks while you are away at work or spending the day downtown. Because your sprinkler mainline is under constant pressure, thousands of gallons of water begin rapidly pulsing directly into your yard for hours.
By the time you get back, you are greeted by a flooded lawn, ruined landscaping, eroded topsoil, and a massive, heart-stopping water bill.
Here in the Lowcountry, our dense, heavy clay soils and flat terrain make standing water a major structural hazard. When a pipe breaks in the Summerville area, the water doesn't easily sink away—it pools, compromises foundations, and turns expensive landscaping into a swamp.
While investing in a smart, Wi-Fi-enabled controller like the Hunter HPC is a fantastic first step for managing weather schedules, standard controllers are missing a critical sense: they can't actually see how much water is flowing through your pipes.
To give your home total plumbing security, you need a physical diagnostic tool monitoring the line. At Distinctive Irrigation, we recommend installing the Hunter HC Flow Meter. Here is how this heavy-duty sensor acts as an absolute insurance policy for your home’s landscape.
What Does an HC Flow Meter Do?
The Hunter HC Flow Meter is a robust, commercial-grade brass sensor plumbed directly into your main irrigation line, right after your master safety valve. Inside its housing sits a highly precise, pulse-reading internal impeller that measures the exact volume of water moving into your yard.
When paired with your Hydrawise® software-enabled controller, the meter creates an automatic baseline for your property. It learns exactly how many gallons per minute (GPM) every individual zone in your yard is supposed to use.
If a zone suddenly deviates from that baseline, the system instantly jumps into action.
3 Critical Protections the HC Flow Meter Provides
1. Instant High-Flow Shutoffs (Catastrophic Leak Protection)
If a main lateral line cracks open, or a lawnmower hits and completely shears off a sprinkler head, a massive surge of water rushes through the line. The HC Flow Meter detects this abnormal surge instantly. Through the Hydrawise cloud platform, it immediately instructs your master valve to cut off the water supply to the entire system, containing the leak instantly and sending an urgent high-flow alert to your smartphone.
2. Low-Flow and Clogged Head Detection
Leaks don't just happen from major breaks. If a drip emitter gets clogged by dirt, a lateral line is restricted by live oak roots, or an internal valve fails to open properly, your plants will slowly starve of water. Because the HC Flow Meter is accurate to within ±2%, it catches even tiny drops in standard water volume, alerting you to low-flow conditions before your expensive landscape material begins to wither.
3. Detailed Zone-by-Zone Tracking
Want to know exactly how much your flower beds are costing you compared to your turf zones? The HC Flow Meter generates highly accurate flow reports directly in your app. This lets you track total water consumption down to the single gallon, allowing you to fine-tune your schedules for maximum budgeting and efficiency.
Zero Tunnels, Zero Mess: The Wireless Advantage
A common concern homeowners have when adding sensors to an existing system is the messy labor of running communication wires from the yard back into the garage or house.
Thankfully, Hunter offers a Wireless HC Flow Meter Kit. Utilizing a secure 900 MHz transmitter rated for underground water immersion (IP68), the meter can communicate flow data completely wirelessly across a 500-foot line of sight straight to your controller. This means we can install top-tier leak protection quickly and cleanly, without digging trenches through your driveway, sidewalks, or mature flowerbeds.
