Water Level Measurement
3 Reasons to Rent Water Monitoring Equipment from the Manufacturer
Editor’s note: This article originally appeared on the In-Situ blog in May 2015. There are several reasons you might consider renting environmental sampling equipment: maybe it just makes more sense to rent equipment for a project rather than buy it, or perhaps you want to try the product before you make the commitment. Whatever the…
Read MoreNew Approach to Collection System Assessment & Management
RedZone Robotics has a new approach to collection system assessment and management. Using robots equipped with multiple sensors, collection system inspections can combine conventional qualitative CCTV with synchronized laser and sonar dimension information all collected several times faster than conventional CCTV trucks. This unique full 360° quantitative view of the pipeline can help to pinpoint which lines in…
Read MoreTough Challenges in Sewer Lift Station Level Measurement
Tough challenges for sewer lift station level measurement are operating in an extremely harsh environment; and reliable performance without frequent maintenance. Pump controls are dependent on accurate level sensing; so the level sensor must be designed to withstand these conditions; without the need for constant maintenance and calibration.
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 MoreMonitoring 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…
Read MoreParshall Flumes – Free vs. Submerged Flow
As often as we use Parshall flumes for open channel flow measurement, it is important to understand “free versus submerged flow” conditions; as it greatly impacts the accuracy of the installation…or the lack thereof. While any primary device could be affected by submerged flow conditions, there isn’t much data to be found on the topic.…
Read MoreAquatic Sensor Workgroup Guidance Documents
The Aquatic Sensor Workgroup is a public-private partnership of water-quality monitoring agencies, industry, and academia whose mission is to ensure that water-quality data collected by sensors are of known and documented quality. They have published several guidance documents that benefit anyone using or preparing to use water quality monitoring sensors for surface water or groundwater monitoring applications.
Read MoreComparing Absolute and Gauged Pressure Sensors
This technical note describes the difference between absolute and gauged pressure sensors and explains the proper use of each type of sensor in different applications for In-Situ, Inc. LevelTROLL and AquaTROLL instruments. Figure 1 provides a general illustration of the forces measured by a pressure sensor’s internal strain gauge.
Read MoreLogging Rain Gauge
Teledyne Isco offers two options for a logging rain gauge. The Isco 676 Rain Logging System uses an Isco 674 rain gauge and a 4120 Flow logger (minus the submerged pressure transducer) be to record rain events. The second option, Isco 677 Rain Logging System, uses the same 674 rain gauge but the more advanced…
Read MoreReal-time Water Tower Pressure Monitoring Via the Web
It is as simple as connecting a sensor to an existing tap at the water tower or on a water line within the distribution system and powering up the modem and you can access your water tank pressures or distribution system pressures on the Internet.
Read MoreLow Flow Groundwater Sampling Simplified
Low flow groundwater sampling has become the norm for collecting groundwater samples during preliminary groundwater investigations, long-term groundwater monitoring, and during remedial activities. By using low flow purging and sampling techniques groundwater samples can be collected from a monitoring well that are representative of the groundwater within the formation adjacent to the well screen without…
Read MoreFinally Say Goodbye to Circular Chart Recorders!
ISCO’s Signature meter is for open channel flow monitoring at wastewater treatment plants, industrial pretreatment and permanent outfall monitoring locations. The Signature has bubbler and/or ultrasonic level sensor options – plus an array of additional sensor inputs; such as pH, DO, Turbidity, Chlorine, etc.
