Product DescriptionMain FeaturesStandard volume output, No additional temperature and pressure compensation neededWorking condition volume output, based on real-time temperature and setting pressure valueNo moving components, long-term stabilityCompact design, smaller size to install easilyResistance to 120ºC ambient temperatureDynamic multi-tariffRemote valve operationRemote upgradeable firmwareField swappable batteryEasy operation and maintenance through advanced 3 touch-button human-machine interface.Kinds of communications module are available for various marketsDesign in accordance to smart metering equipment technical specificationsMeasurement PrincipleThe measurement principle is based on a MEMS "Micro Thermal Flow Sensing". The Fig 1 has shown that there is a micro-heating element and two temperature sensors are placed around it. The temperature difference between the two sensors will be created when the flow rate increases and it is proportional to the mass flow rate.
