The Leak Gopher Z-Wave Meter Reader works with a Z-Wave Controller to protect your home or business from water leaks. When the Leak Gopher Meter Reader detects a sudden increase in water usage, the Z-Wave Controller can be programmed to tell a companion Leak Gopher Z-Wave Valve Control to automatically turn the water off, protecting your home or business. The Z-Wave Meter Reader is Z-Wave Plus certified to support the latest Z-Wave Controller capabilities. The Leak Gopher Z-Wave Meter Reader attaches to a water meter with a switch closure (pulse output) output. The Leak Gopher Z-Wave Meter Reader counts the switch closures (pulses). Each switch closure will equate to a quantity of water defined as the meters.
