  • Minimum Flow Units - Case Study

    Environmental regulations are becoming more stringent and the minimum by-pass flow requirements are generally increasing in North-America. Many of our small hydro technologies are perfectly suited for this type of application whether it is to replace an existing pressure reducing valve or implement a new turbine upstream of the by-passed reach of an existing hydro plant. Shown below is an example ...

  • Accuracy Vs Resolution: It`s The Little Things

    For what seems like millennia (ok, maybe not millennia), there has been confusion surrounding accuracy and resolution. Often the two terms are used interchangeably, especially when referring to measurements and instrumentation. But accuracy and resolution are completely different in meaning, so our use of them ought to reflect that difference. Let’s look at some basic ...

  • Hydraulic characterization and transient response of pressure reducing valves: laboratory experiments

    A pressure reducing valve (PRV) regulates the outlet pressure regardless of the fluctuating flow and varying inlet pressure, thereby reducing leakage and mitigating the stress on the downstream water distribution network (WDN). Notwithstanding the crucial importance of PRVs, few experimental data are available in the literature. The aim of this paper is to overcome this gap by means of the ...

  • Kansas Facility Finds Fast, Reliable Fix to Cavitation Damage

    The Hutchinson (Kansas) Water Plant gets its water from 20 wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back ...

  • Birth of an AccuMax

    Head of the AccuMax Family In 2015, we released the AccuMax dispenser as the first in a “family” of dispensers. Our goal is to create a line of innovative, user-friendly dispensers built around real feedback from our customers. So, while we may call the AccuMax our “standard” dispenser, there is really nothing standard about it. It was born, so to ...

  • City Of West Palm Beach Reaches Out To Community With Proactive Approach To Manage Critical Force Main

    The City of West Palm Beach (WPB) makes a concerted effort to engage its citizens. As one of the three largest cities in South Florida, WPB is a vibrant, growing waterfront community with a population of more than 100,000. Since 1974, WPB has experienced exponential growth in its population and correspondingly, in its wastewater ...

  • 10 Flags in Valve Chambers that Should Make You Question What Else is Wrong

    I have reached the conclusion, as a lot of you may relate too, that I may be considered one of those “cranky old men”. It shows itself in the little things. Sentences starting with the phrase “when I was your age” or ...

  • Top 8 things to check when maintaining a Pressure Reducing Valve

    Like every other piece of mechanical equipment we use, a control valve does require some maintenance. As budgets are stretched and time is tight, it can be tempting to ignore checking on valves that are often located in underground vaults and give years of operation without complaint, but eventually like everything else, they will fail. This article looks at 8 simple steps that if undertaken ...

  • Top 10 Valve Considerations for Pressure Management Zones/DMA’s

    For basic pressure management or more advanced modulating pressure management, water suppliers create a network of District Metered Areas (DMA’s) or smaller, more manageable pressure management zones. The DMA or pressure zone gives the ability to measure flow and control pressure, when a Pressure Reducing Valve (PRV) ...

  • Abha water utility comes out on top with automated control valves

    Abha is a small modern city in the fertile mountains of southwestern SAUDI ARABIA. Its cool summers make it a popular destination for tourists, but in general the population hovers around 250,000. The city has a new reservoir on top of a hill that releases water through 6 km of piping down to its main Noaman reservoir. The top tank is 100 meters higher than the lower tank. This makes for a great ...

  • How to Size Diaphragm Actuated Control Valves

    There are many options and several conditions that need to be considered when purchasing the right valve for a job. The more information from the field, the better the choice will be. The ultimate goal is to have the best valve for the job required at the most economical price. While it is not rocket ...

  • Doing The Dos: Five Tips For Taking Care Of Your Sensor Diaphragm

    For all continuous output pressure sensors, no matter the application, the component most sensitive to external factors, and most crucial to sensor functionality, is the sensing diaphragm. If it is not working correctly, either your readings will be incorrect or, in extreme cases, you will have no readings at all. So often in the world around us, we hear “Don’t do this” or ...

  • Changing Response Times

    Timing is everything for your sensors. A sensor that is too sluggish to respond to quickly changing levels or pressure won’t alert you to dangerous process conditions until it’s too late. And an overly sensitive sensor sees an emergency in every stray reading or transient condition. Neither sensor is effective, in terms of time or money. Sensors ...

  • Maintaining a pressure reducing valve: 5 things to check

    Like your car, your body and nearly every appliance you own, control valves require regular maintenance to continue working efficiently. However, due to budget and time constraints, we don’t always give our valves the TLC they need to perform at their best. Unfortunately, ignoring pressure reducing valves can mean serious ...

  • Case study - City of Sault Ste. Marie - Pressure Monitoring

    The condition assessment project consisted of a Sahara pipeline inspection to detect any leaks or pockets of trapped gas on the lines, as well as a period of pressure transient monitoring on each pipeline to check for any sudden peaks or drops in the pressures which could be damaging to the lines. Service: Sahara Transient Pressure Monitoring Client: City of Sault Ste. Marie Type of ...

  • Monitoring of a spark ignition engine malfunctions using acoustic signal technique

    This manuscript presents a fault detection method for a SI engine at variable speeds using acoustic signal technique. Two faults were addressed: misfire and the malfunction of manifold absolute pressure (MAP) sensor. The main objective is to detect these two faults by measuring the sound pressure level (SPL) in decibels (dBA) at different engine speeds and one octave frequency bands in the ...

  • 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 ...
