Compatible with multiple Hunter controllers, it delivers real-time data and leak alerts, enabling users to optimize irrigation, reduce water waste, and protect landscapes from damage. Its solid brass construction ensures long-lasting performance in harsh outdoor environments. ## Description Precision, reliability, and protection—built into every drop. The Hunter HC100FLOW 1" Flow Meter is the smart irrigation upgrade that turns water usage into actionable insight. Whether you're a DIY homeowner optimizing a lawn zone or a commercial landscaper managing multiple stations, this flow sensor brings visibility and control to any Hydrawise-enabled system. Review: Used to measure correct water usage for lawn. - I purchased the 1” Hunter flow meter primarily to measure water usage on the lawn to determine correct water usage. I am using this meter with the HPC Hydrawise compatible face panel replacement with my old (2017) Pro-C controller. Many recommendations for watering a lawn are in gallons per square foot/week or inches per square foot/week (easily convertible to gallons). Irrigation controllers typically are time based. With this meter I can now get a good estimate of how much water is going onto the lawn and make adjustments accordingly. I installed this meter between the anti-siphon valves and the zone valves boxes. According to the installation instructions I left about 12” straight inline on the intake and exhaust sides. The instructions also recommend to remove or bypass and drain the meter if you live in a climate where you need to winterize. To do that I installed the meter with L union PVC fittings and built a replacement piece with compressor fitting for winter blowout (see image). The meter has a solid brass body so can imagine would not do very well if full of water and frozen. One other consideration is that this meter does have some drain on water pressure. According to the charts in the installation manual I can expect about 4psi drop using the 1” meter and 10 gallons/min draw (my maximum). With a starting pressure of 62psi that was not a problem for me. Initial tests comparing the utility water meter (in cu/foot) and this Hunter meter (gallons) show that they are fairly close. A much cheaper way to get water estimates is with a tin can and measuring stick. That works unless you have subsurface drip irrigation, but in any case not as much fun as measuring/controlling usage from your laptop/phone. So far I have been able to reduce lawn water usage in half using measurements from this meter. I was overwatering using the time based irrigation method. Using this meter and the Hydrawise app to adjust for weather and seasonal variations is working great. Review: Provides great information and peace of mind if your away often - I added this simply because I am away from home often, and it has the great feature to be able to sense if water is exceeding what is normally flowing during a watering cycle from a zone, you will get an alert. You can then react and shut down the system and avoid major issues. I have also found it really interesting to see how much water each of the different zones has been using. ## Features - KNOW EXACTLY HOW MUCH WATER YOU’RE USING: Stop wasting water and money.

You can then react and shut down the system and avoid major issues. I have also found it really interesting to see how much water each of the different zones has been using. ### ⭐⭐⭐⭐⭐ Easy to install, very useful with Hydrawise system *by C***Y on November 3, 2020* Adding this flow meter dramatically increases the usefulness of the Hydrawise sprinkler management system. I dug up the area around our back flow preventer device and added this flowmeter downstream in a straight length of pipe. Requires straight pipe at least 10 inches upstream and 5 inches downstream of the flowmeter. The signal output flex conduit is relatively short, but by loosening the mounting screw I was easily able to rotate the meter display assembly to allow the flex conduit to exit directly towards my junction box. The thread on the end flex cable takes a M6-1.0 nut (from Home Depot) to mount into a hole in a junction box. ## Frequently Bought Together - Hunter HC100FLOW 1" Irrigation Flow Meter, Smart Water Meter for Sprinkler Systems, Leak Detection Sensor, Flow Monitoring, Compatible with HC, Pro-HC, HPC, and HCC Controllers - Hunter Hydrawise Pro-HC 24-Station WiFi Smart Sprinkler Controller, Outdoor Irrigation Timer, Weather-Based Watering System, Flow Sensor Ready - Hunter Sprinkler WRCLIK Wireless Rain-Clik Sensor System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/207520010-hunter-hc100flow-1-irrigation-flow-meter-smart-water-meter-sprinkler](https://www.desertcart.sn/products/207520010-hunter-hc100flow-1-irrigation-flow-meter-smart-water-meter-sprinkler) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-22*
