ON OUR RADAR REAL-TIME CHLORINE MEASUREMENTS in drinking water LACROIX’s latest sensors can facilitate strict monitoring of chlorine levels in drinking water, putting utilities at a peace of mind. Controlling the level of chlorine in water networks is crucial to guaranteeing the quality of drinking water. Monitoring active chlorine levels in drinking water distribution networks is becoming more important across the world, while regulations in some countries have made it imperative that water suppliers can constantly monitor these levels. To solve the challenge of active chlorine level monitoring, LACROIX has developed the ChlorIN sensor. When connected to a SOFREL data logger, it collects chlorine levels at regular intervals. This continuous monitoring means that an alert can be sent to the operators and the centralisation software should the chlorine level exceed or fall below thresholds set in the software. This brings numerous savings to the operator, from less travel time and working on-site, to supplying more extensive data. The sensor can be installed anywhere on the water network, and it can be used to monitor critical, strategic, or interconnection points, as well as at the end of the network. The internal battery has a service life of up to 10 years. A version with an external power supply is also available, allowing the data logger to be powered for even longer via an external source, be it a battery, mains power or a solar panel. The sensor can be installed to existing water pipes, without interrupting the flow of water. The attached sampling valve allows for immediate sensor calibration. Data is transmitted via 2G/4G networks, via an integrated high-capacity antenna. The ChlorIN sensor is also available with an additional CPR pressure sensor for service quality measurements. SOFREL DL4W OPENSENSOR DATA LOGGERS FOR MORE SENSOR OPTIONS The new range of SOFREL DL4W data loggers allows the connection of up to eight sensors, thanks to an open Modbus connection. The open Modbus model allows the data loggers to meet the monitoring needs of both drinking water and wastewater networks. The high power model is preequipped with a connector allowing the connection of an ultrasonic level probe and is usually used for self-monitoring and permanent diagnostic needs. The RS-485 serial input is compatible with all Modbus RTU equipment. Two additional DIs make it possible to also measure pulses, for example, to signal the opening of the manhole cover, or to monitor an overflow sensor or rain gauge. The ChlorIN sensor from LACROIX installed retroactively on a water pipe The ChlorIN sensor is equipped with a sampling valve for sensor calibration Like all of the SOFREL data loggers, the DL4W also comes with an enhanced IP68 waterproof rating, an integrated 2G/4G M2M antenna, and a three-year manufacturer’s guarantee. 54 WATER & WASTEWATER ASIA | SEPTEBMER/OCTOBER <strong>2022</strong>
ON OUR RADAR SENSOREX OFFERS chemical resistant toroidal conductivity sensor Inductive sensors using polyether ethyl ketone delivers reliable conductivity and concentration in extreme conditions. Headquartered in California, Sensorex specialises in the design and manufacture of quality sensors for critical measurement of water quality. The company offers more than 2,000 sensors for pH, ORP, dissolved oxygen, free chlorine, chlorine dioxide and other specialty parameters, as well as a line of sensor accessories. Sensorex’s new TCSP series toroidal conductivity sensors have been designed for use with harsh chemicals or corrosive elements. With a measurement range up to 2,000mS, it is a versatile sensor with applications across a broad range of applications that would damage typical contacting conductivity sensors. Resistant to corrosion, coatings and fouling common to contacting conductivity sensors, the TCSP3020 is designed for minimal trouble and long service life. The body is made of chemicallyresistant PEEK (polyether ethyl ketone) for use in aggressive chemical solutions and temperatures up to 266°F (130°C) and pressure up to 295 psig (nine bar). A built-in 1000Ω Pt RTD provides output for automatic temperature compensation ensuring accuracy even when sample condition varies. All Sensorex TCSP probes are supplied with a 9-conductor cable with tinned ends for easy connection to controller, transmitters and other devices. The probes are available as standard with 10ft (3m) or 20ft (6m) cables, and custom lengths available on request. WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER <strong>2022</strong> 55
