  • Consumption estimation with a partial automatic meter reading deployment

    Automatic water meter reading (AMR) is now the best kind of technology to supply real time information on water consumption. Complete equipment of a district metered area enables the assessment of the total consumption of a finite size population, for a time scale sometimes as short as an hour. However, its cost for generalization can generate high capital expenditures (CAPEX), unaffordable for ...

  • Understanding 4-20mA Communications

    Imagine this: You’ve got your meter with 4-20mA output setup. Confidently, you flip the switch, turning it on, and then it happens: the readings are off. You’re not getting the output you need. Frustrated, you tinker with it, and still nothing. Now, you’re out of your depth. You need to get this thing working so you can get your application up and running. What are you ...

  • What is turbidity?

    Turbidity measures the relative clarity of a water sample. It is determined by the amount of scattering that occurs when a light source is shined through a water sample. Light scattering is caused by increased concentrations of suspended particles in water that are not individually visible to the naked eye, which can give the water a cloudy appearance. This parameter is used as a general ...

  • Soil CO2 Flux Measurements -- Addressing Spatial Variability: Determining the Number of Readings Required

    Soils can be highly variable in terms of CO2 flux values. Even at a seemingly uniform site, the soil CO2 flux might range from 2 μmol/m2/s at one location to over 4 mol/m2/s just a few meters away. To obtain reliable site mean flux values, it is important to determine how many readings might be required so that time and resources can be properly allocated before starting an investigation. In ...

  • Radiation Monitors and Meters

    Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is ...

  • The Function of an Ultrasonic Flow Meter

    Running a water management operation requires taking a wide range of measurements. In addition to measuring the flow in your system, many systems must measure the water level of their channel, and one of the best tools for accomplishing this goal is an ultrasonic flow meter. ...

  • Your electric meter: A villain or hero?

    Before energy became a hot topic, no one cared about the electric meter.  It was the box on the house we all ignored except the guy from the utility who dodged the barking dogs to take a reading from it once in awhile. It is a sign of our times that this box now inspires enough emotion for people to take to the streets. Protesters gathered outside the California Public Utilities Commission ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • Smart Water Metering For Smart Cities

    One of a city’s most important pieces of critical infrastructure is its water system. With populations in cities growing, it is inevitable that water consumption will grow as well. The term “smart water” points to water and wastewater infrastructure management system. A smart water system is designed to gather meaningful and actionable data about the flow, pressure and ...

  • TDS and EC meters for hydroponics explained

    As technology advances, questions inevitably follow. Due to the rapid growth of the hydroponics and indoor gardening industry, it is important for growers to be familiar with the technology, in this case instrumentation. There is a myriad of nutrients and fertilizers available to help you cultivate the best possible plant yields, but what is consistent among all of them is they need to be ...

  • Electronic Water Meter For Leakage Repair - Case Study

    Every year, EMS (Energy Management System) produces and markets smart electronic water meters (domestic/ bulk), wireless transmission data logger (GSM/ GPRS), and advanced AMR (Automatic Metering Reading) systems. Unlike traditional mechanical water meter, the magnet-free electronic smart water meter with class C (CNS 14866) metrological performance can maintain 12 years battery lifespan. With a ...

  • Case Studies Demonstrate the Implications of Metering Errors

    General anomalies that occur in the management of apparent losses are identified and include determination of apparent loss indicators that fail to take into account both the random and bias errors inherent in metering. Estimating the volume of water losses that could be attributed to meter errors is also incorrectly assumed to be equivalent to the error limits (i.e. envelope) stipulated in ...
