Water and network monitoring

Really simple to set up and install, the RG20 or RG25, paired with a datalogger, can be used equally well in temporary or permanent rainfall monitoring programmes. The rain gauge is connected to a logger which records the local data by radio, or on a remote supervision tool. This ‘tipping bucket’ rain gauge consists of a funnel collector with two calibrated containers designed to prevent the rain from splashing internally or externally, as recommended by the WMO (World Meteorological Organization). The data can be logged either by time stamping the bucket tips, or based on cumulative rainfall, and the device can be programmed to issue alerts.  

The wireless LNU is an acoustic imaging level sensor designed to measure water levels in difficult environments. This multi-purpose sensor, recognised for the precision of its measurements, can be coupled with a physico-chemical sensor or used with samplers. An all-in-one, self-powered system, it measures and logs data before transmitting it to a supervision platform. The LNU is simple to install, use and maintain. It can be securely programmed via radio without any physical interaction on the sensor or direct contact with water, making it easy to maintain.

The ZM flow recorder uses a tried and tested induction process to measure the water flow. This mobile solution simplifies the sectorisation of plastic pipe networks, to identify the zones where leaks may be present and causing water loss. The logged data is then transferred to a dedicated software program, for simplified analysis and global surveillance of the network.

OSRAI FLOW is a self-powered communicating system that reliably converts a measurement of water height into flow. It considerably reduces the margin of error when calculating water levels in confined spaces. Easy and quick to install on sewage pipes, it can be adapted to the limitations of the existing environment or sewer manhole invert. OSRAI FLOW calculates the flow on a wide range of collector slopes, starting from the height of the measured water. The patented OSRAI FLOW system is based on the ‘obstruction’ principle, and the relationship between flow rate and pressure drop. Its innovative shape limits the risk of clogging and guarantees reliable flows for upstream slopes, up to 4%. It can be installed in an existing well.  

A physico-chemical buoy is a fully-integrated, single-parameter device used to monitor the physical and chemical properties of natural waters. When installed in a river, the buoy acts as a datalogger and also as a water quality probe, which is interchangeable depending on the type of measurement required (pH, dissolved oxygen, turbidity or conductivity). It can easily be installed by just one person. Data are retrieved remotely using a supervision tool.  

LOGAZ is a self-powered gas sensor, which accurately detects and measures the presence of H2S in the sewerage system. Easy to use, its measurement and calibration cell can be changed on-site. LOGAZ can be used equally well for local or remote measurement programmes; when used remotely, the data can be transmitted to various SCADA and FTP platforms.  

DRULO III is an ultra-precise portable device that measures the pressure and temperature of the water network. With a built-in datalogger, it can store up to 1.8 million measurement values. This type of control helps with network diagnosis, optimises operating costs and is responsive if a fault is detected.

The LP025 is a datalogger with a built-in pressure sensor. It allows the rapid installation of a pressure gauge on the fire hydrant, without affecting functioning of the drinking water network. The pressure sensor is integrated with an IJINUS LOG datalogger, which records and transmits the data from the sensor by radio or GPRS. Compact and with no need for an external power supply, it guarantees simple, reliable measurement of pressure.  

SENSE is a network access point installed as a traditional connection on the drinking water network. It comprises a clamp and connecting valve that forms a ‘smart’ connection to allow permanent monitoring of the water network. The system can be fitted with sensors, tailored to your requirements. The sensors detect and pinpoint leaks, particularly on plastic pipes, thanks to a submerged hydrophone, and also allow multi-point correlation, the checking of network pressure and water temperature using dedicated sensors. The sensor on this innovative connector can easily be changed, making it an innovative tool that enables optimal supervision of the network.
