Direct Burial Meters Offer Significant Savings
4/13/2020
Most pipelines are below grade, so vaults have traditionally been installed to provide access to any place where a meter and valve are necessary. Vault pits tend to be large, and the installation is by far the biggest expense of a metering project. The good news is that direct burial metering options can greatly simplify the installation requirements, significantly lowering the costs, while also boosting safety.

Evolution Of Pipeline Leak Detection
11/5/2019
As the sheer number of pipelines crisscrossing the country continues to increase, there is an urgent need to ensure pipeline infrastructure safety. The age of many of the pipelines and the number of different products flowing makes this a challenging prospect. Now, new technology has been developed that meets the need for reliable protection that complies with regulatory requirements while eliminating false alarms.

Optical Oxygen Sensors Promote Efficiency Gains
10/18/2019
Tight control of the biological process in aeration basins is the lynchpin of wastewater treatment at municipal facilities. To perform at their peak, the “bugs” in these basins require a specific amount of oxygen. However, the air blowers controlling this process consume a significant amount of energy and thereby represent a major expense. Now, advanced solutions are available that provide a cost-effective method to measure the oxygen for automatic control in the basins without the need for frequent maintenance.

Next-Level Flow And Level Instrumentation
10/16/2019
Trending issues require innovative solutions, and KROHNE is here — in the marketplace, at WEFTEC, and on video — to help water professionals overcome their toughest challenges. Tune in below for Richard Lowrie, Water and Wastewater Industry Manager for KROHNE, as he presents two cases in point: the TIDALFLEX flow meter and the OPTIWAVE 1400 radar level transmitter. The former performs accurate measurement in partially filled pipes — down to 10 percent — which is especially useful for stormwater/combined sewer overflow (CSO) applications, while the latter is a new offering that provides continuous, non-contact level measurement in tanks, pumping stations, and open channels. Learn the unique properties and benefits of each, and how they can update and improve your operations.

A Cost-Effective Answer To Partial-Pipe Flow Metering
10/14/2019
One of the most perplexing challenges for wastewater plant operators is the need to measure the various sources of influent. This is especially true for closed-pipe systems where the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement.

Navigating The Partial-Pipe Flow Challenge
10/10/2019
One of the most perplexing challenges that wastewater plant operators face is the need to measure the various sources of influent. For closed-pipe systems, the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement. The good news is that there is an emerging solution that measures flow in a less-than-full pipe.

Squeezing Every Last Dollar From Biogas
10/8/2019
A growing number of wastewater treatment plants are banking on biogas from their sludge as a supplemental power source. Unfortunately, biogas is notoriously difficult to quantify. Ultrasonic flow meters specifically designed for biogas applications can provide a solution that addresses many of the issues created by traditional technology.

A More Cost-Effective Measurement Solution For Open-Channel Flow
10/7/2019
Until recently, radar level measurement devices have been cost-prohibitive for most municipalities. Newer advancements, however, have brought the cost down significantly, so it is now feasible for wastewater plant managers to consider adopting the technology for open-channel applications.

Achieving Level Pressure At Challenging Points In Distribution Systems
5/31/2019
When drinking water leaves a treatment plant through giant pipes, with the help of huge pumps, the pressure can exceed 200 psi. The high pressure is a necessity because water must travel a long distance in some cases. Water towers scattered throughout the distribution system aid in the process so it can reach all utility customers. The problem is that not all distribution points in a water system are created equal.

Temperature Monitoring Provides Additional Checks On Microbiological Conditions
5/30/2019
Effective control of the microbiological environment in water distribution systems is one of the biggest keys to providing a healthy product. When it comes to processes for achieving this, the U.S. can some take lessons from Europe, where utilities are more likely to monitor temperature. Advanced flow metering technology that incorporates temperature monitoring provides a significant tool for utilities without the need for additional instruments.
