Data on Demand is a very simple system designed to read your meters automatically as often as every one minute. Vision Meters, equipped with 900 Mhz radios, transmit a string of data on a routine basis, (typically every 10 seconds). The meter’s data will be collected by any DataGate installed within 1000 meters and within a clear line of sight. The DataGate can be connected to the Internet via Ethernet or information can be repeated via other DataGates. A direct connection can also be made to the DataGate from a nearby computer which also has a DataGate connected.
