Solar Power for Flow Monitoring without AC. No Power No Problem.
Solar power arrangements for flow monitoring systems can be an effective remedy for remote locations where power is often unavailable, or too time consuming / expensive to run. Several models of flow meters, auto samplers and water quality analyzers come in models that can operate on 12 or 24 VDC. A solar power system mainly…
Read MoreSafety Moment – City Engineer Loses His Life After Entering A Manhole To Retrieve A Flow Meter
On May 28, 2003 a 32 year old city engineer entered a 7’4” deep manhole to retrieve a flow meter and lost his life. Air quality monitoring performed in the manhole at the time the fire department retrieved his body indicated an oxygen concentration of only 2.1% and flammable vapors over 60%.
Read MoreA Comparison of the Dye Dilution Method to Continuous Wave Area Velocity and Clamp-On Ultrasonic Flow Meter Technology
We were recently called upon to perform flow validation in a wastewater treatment system at a power plant in Alabama. They were performing a dye dilution flow study and were looking for alternative methods to validate the flows derived from their dye study. In the Dye Dilution method the flow rate is measured by determining…
Read MoreTeledyne Isco 2150 Flow Meter Found After Hurricane Isaac
For several years the Louisiana Coastal Protection and Restoration Authority has utilized 3 Teledyne Isco 2150 Area Velocity Flow Meters to monitor freshwater flow into Coastal marshes. The Caernarvon Freshwater Diversion Project takes sediment laden freshwater from the Mississippi River and allows it to flow into the marsh providing nutrients and sediment needed to restore…
Read MoreWater Quality Monitoring With Remote Data Access
The need for remote data access for water quality monitoring stations is on the rise. Not only is there a significant cost involved in sending personnel into the field but there are also safety concerns in working in, over, and near the water. In addition, staff shortages can result in “stretching” out the time between…
Read MoreSolution for Excessive Approach Velocity In Flumes
Accurate flow rate measurement is highly dependent upon the approaching flow conditions. The approaching flow should be well distributed, laminar, and free of surface waves. To aid in the transition of flow from what is typically a wider approach channel into the flume, the use of curved wingwalls or flared transitions should be used to…
