Gas & Water Meters

Smart gas and water meters promise to give building managers important tools to lower utility bills and increase safety. The flow meters can only provide those benefits if they incorporate high-performance electronics. This is why Littelfuse makes industry-standard solid state relays to open and close flow control valves, thermistor temperature sensors, and reed switches for access control.
