10 Water/Wastewater Remote Flow Measurement in Open Channels
Teledyne Isco (USA) introduces the LaserFlow Velocity Sensor, which remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The sensor measures velocity with a laser beam at single or multiple points below the surface of the wastewater stream.
"We are very excited about the LaserFlow,” said Kaushal Trivedi, Flow Meter Product Marketing Manager for Teledyne Isco, “because it is ideal for a broad range of wastewater monitoring applications. This is a first for Isco and for the market.” He adds: “This sensor has versatile configuration options that give the user the flexibility to measure flow in most open channel applications.”
Some of the features for the LaserFlow Velocity Sensor include: Non-contact velocity and level measurement during normal conditions; Continuous, uninterrupted flow measurement during submerged conditions; Single or multiple point measurement below the liquid surface; Robust, submersible enclosure fulfills IP68 environmental requirements; No deadband from measurement point in non-contact level and velocity measurements; No need for manual velocity profiling with handheld meter; Bidirectional velocity measurement; Above-ground deployment and removal for increased safety and reduced time.
The LaserFlow Velocity Sensor is just one of Teledyne Isco’s many products that are available for your application. To learn more about this and other flow meter products, please contact them for more information 800-228-4373 or

Get Information on Water Level, Temperature and Conductivity Straight to your Desktop
To provide reliable and economic instrumentation for monitoring of surface and groundwater parameters UIT (Germany) has recently launched its new Compact data loggers with several different measuring cells.
This high quality data logger for monitoring the level, temperature and – optional – conductivity provides all components that are required to measure, store and transmit data.
These dataloggers include various options for data transmission, such as http, ftp, SMS to inform the user about alarms or any other excess of thresholds. Additional warning messages on status parameters like battery status are available, as well as remote diagnostic features.
This compact data logger unit measures only 45 mm in diameter and is therefore ideal for observation wells from 2" on. Great for under floor installations – thanks to reliably working antennas.
The lithium battery pack as well as the GPRS/GSM modem is integrated in that logger unit. For efficient maintenance batteries can be easily swapped, even in the field.
Through an air compensating capillary for barometric pressure compensation a precise working pressure sensor for water level monitoring is used. However water quality monitoring based on an accurate conductivity measuring cell is also possible.
Finally a user friendly operation software (SENSOlog) that completes the system. This software provides various tools for configuration, reading and analysing data within one program.

Water Level and Temperature Logger Simplifies Deployment and Data Collection
The LeveLine from Aquaread (UK) is a self contained data-logging device that records water level and temperature continuously during its deployment. It features a highly accurate Piezoresistive, ceramic pressure sensor and a temperature thermistor, which are powered for up to 10 years by the internal 3.6V lithium battery.
Capture the water level data as quickly as 10 times per second and store up to 500,000 data records on the instrument’s built-in memory. All this technology is neatly sealed within a small, corrosion resistant, titanium housing (22mm x 186mm) that can be deployed to measure either absolute or gauge pressure.
Deployment simpler: The LeveLine is the only water level data logger that utilises the QuickDeploy key allowing you to initiate preprogrammed logging schemes as you deploy. The QuickDeploy key also zeroes the depth against the measured air pressure and checks the battery and memory levels giving simple LED indications. This simple sanity check could save you a costly mistake.
r
Data collection simpler: The GPS LeveLine meter is an accessory that can be used to define and initiate a logging scheme live in the field. When connecting the meter to the LeveLine logger at the time of deployment, the GPS location coordinates are embedded into the memory of the logger. This can make post-organisation of multiple units much easier as each unit has its precise deployment location embedded into it. No time-consuming serial number cross-referencing required here. Using the LeveLine PC application you can produce a Google Earth map of your deployment site with markers for each LeveLine, which will display key data when selected.

The advanced specifications of the LeveLine already make this instrument stand out from the crowd. By simplifying both deployment and data collection, using the novel quick deploy key and the unique GPS embedding features, the LeveLine should be your first choice for water level monitoring.
