6 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 MoreOptimizing Your Treatment Process with Microscopic Particulate Analysis
Are you optimizing your treatment processes by using data from a microscope? Are you monitoring your drinking water source water for algae blooms that could cause taste and odor issues? Or, is your team short-staffed and overwhelmed with other responsibilities that result in the microscope in your lab collecting dust and your team to have…
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…

The release of the Isco FlowCalc app for the iOS platform during WEFTEC 2012 received an excellent response. I am now pleased to announce that Teledyne Isco has made the application available for the Android platform. The Android version will have the following additional features: Calculation for the Manning Equation Calculation for the Cipolletti weir…
Read MoreValidating MagMeter Calibration
Electromagnetic Flow Meters (commonly referred to as magmeters) are one of the most common techniques for metering flow in the water / wastewater industry; primarily because, when installed properly, this is one of the most accurate and reliable measurement techniques available. Magmeters are factory calibrated on precision test stands; usually to NIST traceable standards. Over…
Read MoreFundamentals of Electromagnetic Flow Meters – Grounding
To understand the importance of grounding in Electromagnetic Flow Meters (EMF) let’s start by making sure we understand the basic principles of an EMF. EMFs theory of operation is Faraday’s Law of Induction which states that a voltage is induced across a conductor moving through a magnetic field. In terms of an EMF this means…
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 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…

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 MoreTeledyne Isco Flow Calc App for iPhone and iPad
Teledyne Isco introduces “Isco FlowCalc,” an iPhone/iPad app that calculates flow rates in open, non-full channels and pipes. Teledyne Isco is the first company in the world to provide these features in an application for mobile devices. The app can be downloaded from the iTunes App Store using following link: //itunes.apple.com/us/app/isco-flowcalc/id585920226?mt=8
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 MoreApplying Ultrasonic Clamp-on Transit Time Flow Meters
Ultrasonic clamp-on transit time flow meters offer a non-intrusive method of flow measurement of liquid filled pipes and are a useful tool in many temporary and some permanent full pipe flow applications. Because the sensors are installed on the outside of the pipe, these type of meters are easy to install, making them a good…
