WATER   Stations – networks for qualitative and quantitative monitoring of the waters   Integrated monitoring systems for qualitative and quantitative parameters of surface and underground waters. Our company have designed and installed networks for continuous monitoring and telemetric transmission of parameters, supported by auto-manipulation software. Each one of the networks consists of a number of individual stations which measures and records qualitative parameters (such as pH, conductivity, dissolved oxygen, temperature, Redox, nitrates, phosphates, etc), as well quantitative parameters (such as level, flow, etc). Many of the stations except the water parameters, measure and record other data, such as rain, air temperature, air humidity, wind speed, etc. Most of the systems are energy independed and uses wireless communication with the data collection station. Due to the above advantages the stations are very flexible and complete independed, from any type of facilities (main power, phones lines), in the place of the installation. Our company as a leader with big experience and deep knowledge has installed networks, in Greece, Bulgaria, FYROM, Albania etc.   Water Samplers   Vertical type water samplers, for surface waters (rivers, lakes, tanks, etc), able to take sample from discrete depths. Horizontal type water samplers, for surface waters (rivers, lakes, tanks, etc), able to take sample from discrete depths. Water samplers for surface water syringe type for aseptic sampling in common syringes. Continuous sampling and samples storage devices, suitable for surface waters as well for ground waters. Continuous sampling and sample storage devices suitable for waste waters. Bailer type ground waters samplers, suitable for samples from discrete depths. Ground water sampler waterra pump type, suitable for large volume samples from discrete depths. Ground waters samplers with pneumatic command. Portable peristaltic pumps for sampling from low depth bore holes. System for samples taken from isolated zones. The system is installed and uses only one bore hole and the zones isolated with packers. The systems offer the advantage of sampling from the discrete zones, as well as the ability of the continuous monitoring of the pressure from each zone. These data can be recorded and transmitted via telemetry. The system can be expand in order to measure and record in continuous basis the water’s quality parameters separately for each one of the discrete zone.   Level   Submersible level sensors, piezoelectric or vibrating wire type, with analogue output, for digital recorders (data-loggers) or PLC-SCADA units. The sensors have automatic barometric pressure and temperature compensation. Ultrasound level sensors. Automatic level recording systems for surface or ground waters, with or without telemetry. Complete submersible level recording units, able to accept additional sensors. Floater type level recording units. Complete range of data-loggers for level sensors. Level meters with various tape lengths, with audible and optical signal, with adjustable sensitivity, with flat or coaxial tape. Self drive piezometers for use in saturated soils. Multiple zones piezometers for isolated zones in the same borehole. Nets of telemetric level monitoring.   Flow   Classic current meters for open channels or rivers, using rods or suspended method. Low volume – weight digital instruments for flow measurement in open channels. Instruments for flow measurements in closed tubes. Devices for flow measurements in drainage systems. Continuous flow recording systems.   Samples   Complete series of sensors for any water quality parameters, with analogue output for data-loggers or PLC. Complete series of portable instruments for quality parameters measurement (such as pH, conductivity, etc). Complete series of color meters and kits (for Nitrate, Phosphate, etc). ON-LINE analyzers for monitoring of quality parameters (COD, BOD, TOC, Nitrate, Phosphate, etc). Multi-parameters portable instruments with and without data- logging facility.
