Read More6 Benefits of Clamp-On Ultrasonic Flow Meters
According to the American Water Works Association, public water systems lose approximately $2.8 billion in annual revenue from water loss. Non-Revenue Water (NRW), combined with the environmental impact, has drinking water specialists looking for more flexible and accurate flow measurement technologies to locate, and quantify, sources of loss. The Transit Time Ultrasonic technique provides a…
Read MoreSolar 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…

By Mary Therese Gookin West Rankin Utility Authority (WRUA) provides wastewater treatment for seven neighboring members serving a population of 100,000. Bruce Stephens, Executive Director of WRUA, a…
Read MoreTemporary Flow Measurement Solution With An Improperly Installed Flume
Recently one of our customers was contracted to perform a temporary flow study at a commercial bakery. The purpose of the flow study was to quantify the volume of process wastewater being discharged so a pretreatment system could be designed and installed to satisfy the requirements of the local water control district. Our customer reached…
Read MoreMultiple Outfall Flow Monitoring Application Challenge
A recent application challenge was presented to us by an industrial customer in the Southeast Texas area. The customer was relocating their final outfall from their wetland treatment system to a remote area without AC power. They needed a way to measure flow rates in three side by side 36” culverts and collect flow weighted…

Read MoreExcessive Approach Velocity in Parshall Flume Flow Measurement Applications
Since the 1930s, wastewater professionals have relied on the Parshall flume as the primary device for open channel flow measurement applications. Parshall flumes provide a very repeatable relationship between water level (Ha) and flow rate; but, only so long as the approaching flow conditions are appropriate. For any flume design, the hydraulics must cause a…
Read MoreFundamental Principles of Electromagnetic Flow Measurement
Just as valuable as Teledyne Isco’s Open Channel Flow Measurement Handbook, Krohne’ has “written the book” on magmeters. Download your copy of the Fundamental Principles of Electromagnetic Flow Measurement by Friedrich Hofmann of Krohne. This book describes:
Read MoreDon’t Forget Your Calibration
Calibration of permitted outfall equipment is a requirement on most NPDES permits today and can prove to be valuable documentation when the regulatory agents come visit. C.C. Lynch provides flow meter, sampler, and parameter equipment (i.e. pH, DO, Turb, etc) calibrations onsite and will provide the necessary documentation to satisfy regulatory agencies.
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 MoreProper Flow Meter Mounting
The mounting location of your flow meter is critical to the overall flow monitoring station layout. It should be in a convenient location that lends to easy access for authorized personnel while taking into account security and environmental considerations. In open channel applications where a flume or weir is used, the meter should be located…
Read More“Made for the Shade” Temperature Effects on Ultrasonic Sensors
Ultrasonic flow meters are commonly used to measure flow through a flume or across a weir. Often, the temperature effects on ultrasonic sensors are overlooked in the design and installation process. This type of flow meter utilizes an ultrasonic sensor which is mounted above the flow stream. The sensor transmits a sound wave, or pulse, which is reflected off…
Read MoreA Solution for Excessive Approach Velocity in Flumes – The Energy Absorbing Manhole
Excessive approach velocity caused by pump flow or steep pipe slopes can be an issue in some flume applications. One of the tools we have to solve this problem is the Plasti-Fab Energy Absorbing Manhole Brochure. The manhole features an energy absorbing plate that is slightly larger than the incoming line. The water hits this…
Read MoreBattery Maintenance for Solar Panel Systems
Battery maintenance for solar panel systems is an easy way to maintain reliable service and extend equipment lifespan. Solar panel power arrangements are practically maintenance free…practically. We recommend an inspection routine at least annually – to help intercept problems before they happen and prolong the life of the battery.
Read MoreWhat’s a Packaged Metering Manhole?
The Packaged Metering Manhole was introduced to the wastewater market by Plasti-Fab, Inc. in 1982. In its simplest form it consists of a flume molded into a composite (FRP) manhole. The full range of flumes may be integrally molded into the composite manhole, along with inlet and outlet adapters, pipe stubs, and monitoring accessories for…
