Listing Detail Tabs

Detect water leaks before they devastate your milk / farm / horticulture growing production and waste valuable water resources by installing flow meters into your water lines to show where your water is going.

Monitor water use, so that you can maximize your production and minimize your costs by installing these simple, low cost, battery operated, flow meters.
Why spend hours looking for a water leak, when with a few of these flow meters installed around your irrigation system, you can easily see which direction the water is being used or wasted, and how big the problem leak is.
Sensor can be mounted horizontally or vertically.
The display needs to be protected from water, but installation in a common plastic food container screwed to a fence post is ideal.

Choose the correct size to match your pipeline size, or use adapters (not recommended).
