Apparent water losses can be problematic to companies’ revenues. This type of loss is very difficult detect and quantify often associated with meter anomalies. study was motivated by a company’s challenge that links decrease in consumption meters’ malfunction. The aim develop strategy decreasing usage patterns, contributing performance assessment. basis the approach combination statistical meth...

An innovative Volumetric Current Meter (VCM) was designed in order to allow quick velocity measurements in open channels. At first, the coefficient of velocity (Cv) of the device was determined through calibration under different water velocities in the laboratory. The measurement performance was verified by measurements performed in similar flows in irrigation channels using an ordinary curren...

In this paper, we present a mobile fitness proof-of-concept demonstrator that includes several sensors for measuring physiological issues in a human body, i.e., heart rate meter, 3-axis accelerometer for step counter and energy consumption, and bioresistance meter for fat percentage, body water content and galvanic skin response. In addition, we describe user perceptions representing various di...

We have developed WaterWOLF, a new electronic system and signal processing algorithm for evaluating flow components in pipes. These techniques nonintrusively convert an existing flow meter into a high resolution wireless meter for determining flow rates in real-time. These techniques exploit new tunneling magneto-resistive materials (TMR) for detecting very small magnetic fields generated by ce...

Although the agricultural sector consumes more than 90% of the extracted water, its efficiency is lower than other sectors. Also, according to the population growth and critical role of food security, and the necessity to supply water to other sectors, an increasing pressure to save water, optimized consumption and increasing water use productivity in agriculture will occur in the future. Nowad...

In this paper we demonstrate a compact ready-to-use micro Coriolis mass flow meter. The full scale flow is 1 g/h (for water at a pressure drop < 1 bar). It has a zero stability of 2 mg/h and an accuracy of 0.5% reading for both liquids and gases. The temperature drift between 10 and 50 °C is below 1 mg/h/°C. The meter is robust, has standard fluidic connections and can be read out by means of a...
