Hydrant Meters
Accurate Billing for Hydrant Water Use
Metron’s Spectrum® Hydrant meters are designed with a flow range suitable for measuring fire hydrants and other fire service systems. The lightweight, aluminum body meter can be fitted for any utility or construction requirements. It has a robust turbine measuring element capable of withstanding the high flow and the start/stop punishment of these applications. A full cage can be provided to protect the register and optional GPS unit from damage at construction sites and during transportation.
Fitting the Spectrum Hydrant meter with our Prism® register conveniently provides remote cellular-based readings via Metron’s WaterScope®. This allows the utility to track reads and consumption during the meter’s field time. An optional GPS unit also allows the utility to track the location of the meter on Google™ Maps.

Frequently Asked Questions
What is a hydrant water meter?
A hydrant meter, such as Metron’s Spectrum Hydrant, is a water meter designed to attach to a standard city water hydrant. It is used when it’s important to measure how much water is drawn from a hydrant, for example by a construction project. A city typically owns a number of hydrant meters; contractors are required by the city’s permit terms to rent one or more meters for the duration of the project.
What are the important features of a hydrant meter?
A hydrant meter needs to be portable, robust, reliable, and easy to use. The Spectrum Hydrant meter has an aluminum body, making it lightweight and strong. The Prism register automatically uploads water consumption data every night over the cellular network, so there’s no burden on the construction contractor to report usage.
Which cellular networks are used by the Spectrum Hydrant meter?
The register can be configured for Verizon Wireless or AT&T networks.
Do hydrant meters get mislaid?
Yes, it happens. However, the Spectrum Hydrant meter can be ordered with an optional GPS tracker which allows the city to keep track of its location.
