Best for

Adding flow monitoring and automatic leak detection to this catalog's Hunter HPC400 (Hydrawise) — it flags a stuck valve or an overconsuming zone before it shows up on the water bill.

  • Flow meter
  • Leak detection
  • Hydrawise

What is it and what's it for?

A flow meter is like a 'water odometer' installed on the main irrigation line: it measures how much water passes through in real time and flags it when the number doesn't add up — for example, if suddenly twice the normal flow comes through (probably a broken valve) or none at all (probably a clogged line).

Real-world use cases

At home

You have a Hunter HPC400 with Hydrawise installed, and a valve sticks open without you noticing — the meter detects the abnormal flow and the app alerts you that same night, instead of finding out next month on the water bill.

In a business or workshop

A landscaper maintaining several properties with Hydrawise controllers can add this meter at each site to get remote leak alerts without having to visit every yard to check valves by hand.

How to avoid buying the wrong one

  • Only compatible with Hunter's Hydrawise family (HC, Pro-HC, HPC and HCC controllers) — it doesn't work with Rachio, Orbit, or any other controller in this catalog.
  • It installs on the main 3/4" line between the master valve and the zone valves, not on each individual valve — it measures total system flow, not zone by zone.
  • It's stainless steel with union fittings, built for years outdoors, but it showed low stock at the time of this verification ("Only 6 left in stock") — worth confirming availability before planning the install.

The investment takeaway

$147 is a real added cost on top of the $200 the Hunter HPC400 already costs — but an undetected leak from a broken valve can mean hundreds of gallons wasted per week before anyone notices it on the bill. For anyone who already invested in a Hydrawise controller, this meter pays for itself the first time it catches a big leak.

RAINPOINT Soil Moisture Sensor + WiFi Hub + Alerts Kit

Hub includedAlertsRAINPOINT ecosystem
3.7 · 37 reviews

Comes with the WiFi hub included (unlike the standalone sensor above) and adds historical data logging and low-moisture alerts. It integrates directly with the RAINPOINT smart irrigation ecosystem — if you already have or plan to buy a controller from another brand, confirm it supports this integration before buying, since it's a closed ecosystem.

GoveeLife Smart Water Leak Detector (5 Sensors + WiFi Gateway)

Leak detector5 sensorsIP67
4.2 · 2,665 reviews

This is not a soil moisture sensor — it's a leak/flood detector meant to be installed near appliances, under a sink, or in the basement. The individual sensors do NOT talk WiFi directly to each other: they use a proprietary long-range radio (up to 1,804 ft) to a gateway, and it's the gateway that connects to your 2.4GHz WiFi and sends alerts via app/SMS/email. GoveeLife sells this same line in variants with and without the gateway included — confirm in the listing that the one you're buying includes it, unless you already have a compatible GoveeLife gateway from another product (H5059/H5830).
