Wireless Automatic Water-meter Reading System
Wireless automatic meter reading (AMR) system based on a fixed radio network brings many advantages when compared to other meter reading techniques. After an introduction to the state of the art of AMR systems in general, and particularly of water meter reading system, a wireless automatic water-meter reading system founded on ZigBee technology is presented. Set forth in the text are main chara...
متن کاملOptimal Control for Hydraulic System with Separate Meter-in and Separate Meter-out
Individual meter-in and meter-out proportional control of hydraulic cylinders allow more flexible strategies how to handle a payload while optimising certain aspects of the motion. An optimal control approach based on the Hamiltonian is used to plan a motion path for a separate meter-in and separate meter-out system. One goal is to avoid oscillations at the end of the motion in the sense of act...
متن کاملA Sub-Optimal Look-Up Table Based on Fuzzy System to Enhance the Reliability of Coriolis Mass Flow Meter
Coriolis mass flow meters are one of the most accurate tools to measure the mass flow in the industry. However, two-phase mode (gas-liquid) may cause severe operating difficulties as well as decreasing certitude in measurement. This paper presents a method based on fuzzy systems to correct the error and improve the reliability of these sensors in the presence of two-phase model fluid. Definite ...
متن کاملA Low Cost Water Meter System based on the Global System for Mobile Communications
The accurate reading of a customer water-meter is important as it is the main revenue base for the water authorities. The traditional data collection process is still common in developing countries despite the inherent inefficiency, inaccuracy and labour intensity. A solution to improvement could be based on sensor and communication technology. In this research an automatic water meter reading ...
متن کاملA Decision Support System for Optimal Use of Irrigation Water and Crop Selection
We propose a Decision Support System (DSS) for optimal cropping patterns and irrigation water management. The development of the DSS has three objectives. The first is to use mathematical models in order to optimize cropping decisions and irrigation policies under shortage of water in the Kingdom of Saudi Arabia. The second is to help growers exploit optimally their lands in places suffering fr...
