Self Organising Mesh Radio Based Solution for Smart Metering Communication

This paper describes a mesh networking based solution on Routing Protocol for Low power and Lossy network to realize Automated Metering Infrastructure (AMI) network communication. Automated Metering Infrastructure is expected to facilitate the transport of meter readings from meters to the utility provider and control information in the other direction. The smart meters send the meter data to t...

Advanced Metering Infrastructure Security Issues and its Solution: A Review

Advanced metering infrastructure (AMI) is the core component in smart grid. Moreover, two-way communication between the user and the power utility is realized through AMI. Composition of AMI is described. AMI security requirements are illustrated. The threats on the smart meters, communications network, and data collector are analyzed, respectively. Passive and active defenses are investigated....

Evaluation procedures of ultrasonic signals in gas flow metering

In technical processes very often signals are generated which are complex modulated and superposed by stochastic disturbances or noise. A typical example is an ultrasonic wave passing a streaming fluid perpendicularly which is complex modulated by stochastically distributed turbulences. The signal can be demodulated digitally by undersampling to separate the narrow sidebands. The complex modula...

Ultrasonic Transducers for Gas and Liquid Flow Metering

Accurate fluid flow metering is essential for modern process control, and ultrasonic flow meters are well established in this area. However, the specific acoustic impedance mismatch for most piezoelectric ultrasonic transducers is different when operating liquids and gases, hence there are problems measuring two-phase flows when using a single type of piezoelectric transducer in a flow meter. T...
