Water / Wastewater 41 New Submersible Level Probe with Ceramic Diaphragm


KROHNE introduces the OPTIBAR LC 1010 submersible level probe with ceramic diaphragm. Aimed at water and wastewater, environmental engineering and OEM applications, it provides a simple and continuous hydrostatic level measurement solution for water wells, rainwater retaining/overflow basins, or tanks.


OPTIBAR LC 1010 features a robust 316L stainless steel housing and a high overload-proof ceramic diaphragm for long operating life. For safe and easy cleaning on site, the diaphragm is flush mounted. With a diameter of 22 mm/1”, OPTIBAR LC 1010 can be used also in small vessels. It comes with pre-configured measuring ranges from 100 mbar/10 kPa/1.5 psi to up 10 bar/1 MPa/150 psi, customer-specific ranges are available on request.


For versatile use from water to wastewater applications, OPTIBAR LC 1010 features ATEX and IECEx certification and a corrosion-resistant TPE cable that is also approved for use with potable water. Next to the electrical lines for the 4…20mA output, the TPE cable houses an air hose to be used for differential pressure level measurement with closed vessels. With open vessels, the air hose can be capped for absolute pressure measurement. As options, OPTIBAR LC 1010 can be provided with an integrated 3-wire Pt100 temperature sensor, alternatively with HART 7 communication for convenient configuration.


Ballast-Check 2 Performs Well in California State Lands Commission Validation

California State Lands Commission (CSLC) recently completed a validation exercise of three indicative sampling tools while developing their draft compliance assessment protocols.


They evaluated the sampling tools with three different ballast water treatment systems – one UV system and two Electrochlorination systems.


In all three assessments, the Ballast-Check 2 results were very similar to the microscopy and flow cytometry results (mean results over three replicates showed a maximum difference of 3 cells/mL, always matching the risk of exceedance level).


Chris Brown, Senior Environmental Scientist with the Commission’s Marine Invasive Species


Program, presented the results of their validation at the March 16, 2017 ICES/IMO Ballast Water Workgroup meeting. He detailed the planned compliance assessment protocols, if adopted, would be multi-tiered – 1) paperwork, calibration, & functionality; 2) indicative sampling; and 3) full scale testing. Indicative tools such as the Ballast-Check 2 would be employed when the second tier of indicative sampling is deemed necessary.


The Turner Designs Ballast-Check™2 is a small, lightweight, highly durable handheld fluorometer ideal for quick indicative compliance checks of ballast water. Factory set, Ballast-Check 2 is ready for use right out of the box, no calibration necessary. Precision and accuracy of Ballast-Check 2 are optimized for the ballast water D2 regulations.


Extremely simple one-button measurements display estimates of both algal abundance and algal activity, providing ship crew or port state control with an indication of risk for exceedance of the regulation. Small, battery-powered, water-proof, and easy to use, Ballast-Check 2 is perfect for field use. Ballast-Check 2 is ideal for quick on-the-spot, when you want it, assessment of the effectiveness of a Ballast Water Treatment System.


Newly Designed Water Level Logger

Eijkelkamp are very excited to introduce the new Van Essen Instruments’ TD-Diver water level logger as the Mini-Diver’s successor! The new TD-Diver water level logger is a totally new design which combines over 75 years of groundwater monitoring experience with the most recent technologies and components available in the market today.


When developing the TD-Diver


water level logger the focus on long term reliability and stability has remained unwavered. The new TD-Diver water level logger is heavier than its predecessor so you will experience a simpler and smoother deployment down a bore-hole. By adding more memory and processor capacity, compensation and calibration of the pressure sensor has been improved. This gives the TD-Diver water level logger the features to guarantee the best linearity, accuracy and stability.


The conveniently priced Baro-Diver water level logger has also been equipped with the new and improved technologies. This ensures that you accurately capture changes in atmospheric pressure.
