Teledyne 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…
Water 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…
Extend the Life of Your Refrigerated Sampler
The FR series refrigerated samplers by Isco are designed for long life in harsh outdoor environments. The UV protected fiberglass outer shell and powder coated metal components make the FR the perfect selection for all outdoor applications. Most FR units easily last 10 years, but there are few things that you can do to extend the life…
Proper 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…
“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…
A 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…
Battery 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.
Remote Flow Measurement and Sampling Application
Some discharge permits require flow measurement and sampling in highly remote areas. These locations have no other option than to use a solar panel and battery as a source of power. There are many options in selecting equipment for a 12 volt powered system and careful planning is required.
What’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…
Monitoring Water Level At Remote Locations
If you need to monitor water level and rainfall at remote locations it can be done for under $2500 with the In-Situ, Inc. TROLL Link 101 and LevelTROLL. The TROLL Link 101 is a GSM cell modem based system that can transmit data from LevelTROLLs, AquaTROLLs, and TROLL 9500’s to a secure data center hosted…
Solar Panel Batteries and Temperature
In our October blog, we suggested that you err on the side of larger when sizing solar panels and batteries. One reason is that solar panel batteries are greatly affected by temperature; and only one part of this story is good.
Gravity Flow Measurement in Smaller Pipes – Application Toolkit Part 2
ISCO Flow Metering Inserts Gravity flow measurement in smaller pipes (6 – 12 inches) can present challenges; from access, to technique and cost. With everything below grade, access tends to be the final manhole; out near the site’s perimeter. In these cases, ISCO’s Flow Metering Inserts can play an important role in our Application Toolkit.…
