Voyager Hydrant Meters

Download PDF


The Voyager 80 is a hydrant meter 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.  The Voyager has a robust turbine measuring element capable of withstanding the high flow and 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 Voyager with an innov8-VN register conveniently provides remote cellular-based readings via Metron’s Waterscope System.  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.


The Voyager meters utilize an innovative bearing design based on the proven Woltman turbine concept.  A turbine is mounted on a shaft oriented parallel to the flow stream.  The water forces the blades of the turbine to rotate the shaft in proportion to the velocity of the flow.    

Due to the advanced bearing design, the meter maintains accuracy at almost any orientation, including vertical.
