34 Water/Wastewater Slurry Density Meter Launched to Replace Obsolete Technology
SCIAM Worldwide (USA) has introduced an innovation set to transform density measurement of slurries in processing applications. The in-line, continuous density meter, DM3, calculates density by measuring direct mass over a known volume within a flow tube. By directly calculating density rather than inferring or estimation, this technology improves the accuracy, value for money and environmental viability of sensor and mass flow systems. Originally designed to replace obsolete technologies for the mining and dredging industries, the DM3 has proven to be safer and more cost effective than hazardous nuclear techniques or inefficient auto-sampling within any slurry processing operation.
This refreshingly green alternative is suitable for the density measurement of countless industries including water and waste, paper manufacturing, power, oil, food and beverage processing and fracking. The DM3 effortlessly measures abrasive media thanks to its highly resilient gum-rubber lined flow tube with customisation options for high pressure and extreme temperature applications.
Early adopters include industry leaders looking to improve their bottom line by utilising SCIAM’s cutting edge technology. An example of the density measurement systems use is the calculation of percentage dry solids of zircon slurry in a mining application in the north of Florida. The DM3 is also implemented to measure mass flow and density of waste sludge as it is transported from sewage lagoons in waste processing operations of major US cities. By replacing nuclear density meters and auto samplers, early adopters benefit from an increase in accuracy of more than 2.5% resulting in millions of dollars of savings and an immeasurable increase in safety and efficiency.
Reader Reply Card No. Flexible Multilevel Monitoring System
Obtain superior quality subsurface data using a Solinst (Canada) Multilevel System. CMT Systems monitor multiple depth-discrete zones within a single borehole. CMT (Continuous Multichannel Tubing) is polyethylene tubing with three or seven separate channels running its length. Monitoring zones are manually constructed, one in each channel, at different vertical intervals.
CMT Multilevel Systems are inexpensive and easy to install. In-field design flexibility allows the number of monitoring ports, port locations, and monitoring strategy to be finalised right on site. Monitor up to 7 zones in the 1.7" (43 mm) System and 3 in the narrow 1.1" (28 mm) System. Depth-discrete groundwater data provides assessors with a better understanding of the three-dimensional flow and distribution of contaminants in the subsurface.

High-Performance Submersible Pressure Transmitter for Level Measurement
The new LH-20 submersible pressure transmitter from WIKA (Germany) fulfils the highest requirements within level measurement technology. The slender, high-performance instrument, with a diameter of only 22 mm, impresses with an accuracy of up to 0.1 %, even in harsh operating conditions.
As a result of numerous options and functions, the level probe is suited to just about all applications in level measurement with full media contact. The LH-20 exhibits, in addition to a high accuracy, a very low temperature error and is available with a parallel temperature output signal, HART communication and a scaleable measuring range. For the highest resistance to media, the high-performance probe is available in a stainless steel or titanium version, with PUR, PE or FEP cable.
The variety of application possibilities is enhanced by the design of the submersible pressure transmitter. In the specific design variant for drinking water applications, the LH-20 meets the KTW and ACS regulations for drinking water conformity. Furthermore, the probe is available in an explosion-proof version.

Aqualabo Family Celebrates Another New Arrival
Aqualabo Group (France) recently acquired Neosens. They will join Perax (telemanagement) Ponsel (instrumentation) and Orchidis (analysis equipment) as part of this highly focused collection of companies specialising in the monitoring and control of water.
For the last 7 years, Neosens has developed sensors for the measurement of fouling in water systems and process food. Neosens’ innovative technology has undergone a considerable investment in research and development to ensure that it offers a world class range of sensors. This will now expand the range of the group’s probes and further strengthen the advanced technological solutions that AQUALABO can bring to its customers.
The commercialisation of the Neosens range will be carried out by Orchidis who have already established themselves as leading manufacturers of analytical instruments for the water quality analysis sector.

New Portable ‘Mag-Flow’ Current Meter Launched
OTT Hydrometry (UK) has launched a new portable current meter for fast accurate flow measurements in open channels. The OTT MF Pro is robust, simple to use and able to provide accurate measurements in shallow or low flow conditions, even in turbulent, high sediment or at sites where weed growth is an issue.
As an electromagnetic current meter with no moving parts, the OTT MF Pro requires almost no maintenance and never requires recalibration. The instrument’s display guides users through the cross-section measurements and velocity data are graphed in real-time, allowing trends to be visualised quickly. Users can enter depth information manually during the measurement work or an optional depth sensor is available.
At the end of the measurement, the instrument automatically calculates discharge employing recognised international standards for flow monitoring. All data is logged and can be transferred to PC at a later time.
OTT’s Robin Guy, a flow monitoring specialist, says “The MF Pro will be extremely popular with hydrologists because measurements often need to be taken quickly and many rivers and streams are difficult to access, so a lightweight, robust, fast instrument is ideal.”
