Metering Advantages

l   Smaller & Lighter: smaller and lighter than diaphragm meter under the same type.

l   Ultra-High Sensitivity: subtle gas flow can be detected.

l   Wide Range Ratio: G4W can be up to 375:1, G40W can be up to 260:1

l   High Reliability: no moving parts, no losses of measurement accuracy in long term operation.

l   Strong Anti-Interference Ability: digital metering signal output, undisturbed by magnetic field.

l   Temperature&Pressure Compensation: built-in temperature&pressure sensor, outputting cumulative volume under STP (Standard Temperature and Pressure).

Gas Safety

l   Over Flow Detection: meter will close valve automatically at over flow rate to prevent pipe broken.

l   Reverse Flow Detection: when detects reverse gas flow, meter will close valve automatically in case of meter installed wrongly.

l   Continuous Flow Detection: when detects continuous flow, meter will close valve automatically in case of forgetting to turn off the gas appliance and to prevent pipe leakage.

l   High Temperature Detection: when detects gas temperature above the high temperature alarm threshold, meter will close the valve automatically and report to the system in case of meter in fire environment.

l   Air Ingress Detection: when detects air ingress, meter will close the valve automatically and report to the system in case of illegal disassembling from pipe.

l   Water Ingress Detection: when detects water ingress, the valve will close automatically to ensure pipe network safety.

l   Meter Disassembling Detection: when detects battery cover opened or controller disassembled, meter will record a log and report to the system.
