  • 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 ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly the ...

  • 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 ...

  • Results from Australia: Forest Road landfill life extended +50% with TANA E520 compactor

    Optimizing landfill life by choosing the most efficient landfill compactor is giving Forest Road landfill more operation years. "Waste density in completed cells will now be increased from approximately 800 kg/cubic meter to 1200-1400 kg/cubic meter under standard operating conditions", says Jon Beckett, Waste Services Manager. ...

  • 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 ...

  • Avoid common mistakes when buying a decibel meter

    Why it pays to avoid quick fix solutions when it comes to noise monitoring Whether you run or own a construction site, a metal cutting workshop or an open cast mine, as an employer of a noisy working environment, you must ensure that the hearing of the employees you are responsible for is protected. In the UK The Control of Noise ...

  • Full waveform data display

    FlashRES resistivity meter displays full current and voltage data when the system is collecting these data. The real time read out of the data effectively helps operator to monitor the data quality. In case the data quality Q factor drops in value, the operator can pause the data collection process and check the background, contact and instrument noise. Displa full waveforms thus protect ...

  • How to boost the performance of Pressure Reducing Valves without breaking the budget.

    Pressure Management has become a very useful tool around the world for controlling leakage in piping networks. This has primarily been achieved by utilities forming DMA’s (District metered Areas) and pressure zones in their systems. Typically, pressure is managed by utilizing a pressure reducing valve that can either have a single fixed pressure reducing pilot set point or pressure flow ...

  • Sub-metering of natural gas-flexible flow measurement delivers improved accuracy and substantial savings

    Introduction Unlike oil, natural gas exists in abundance in the United States. Of the natural gas consumed in the United States in 2011,95% was produced domestically. The U.S. Energy Information Administration projects U.S. natural gas production to increase from 23.0 trillion cubic feet in 2011 to 33.1 trillion cubic feet in 2040, a 44% increase. Almost all of this increase in ...

  • A CFD study of the effect of venturi geometry on high pressure wet gas metering

    Venturi meter is increasingly being preferred as wet gas flow meter because of its simple construction and ease of operation. It has been found that the performance of venturi in single phase gas is very different from that of water. In this work, with a view to optimise the design, the effects of diameter, diameter ratio and convergent angle on the performance of a venturi meter for wet gas ...
