Water Monitoring Instrument

RV7 Radar Velocity Sensor


RV7 is a non-contact 24 GHz RADAR based velocity sensor that uses Doppler Effect to produce velocity data of a moving surface. The measurement can be widely used for hydrological monitoring, flood control, and environmental pollution monitoring. Non-contact surface flow measurement is simple, free from water corrosion, silt or slurry. It also protects the safety of personnel. The velocity present on a surface is typically within 10% of the average velocity. There is an empirical algorithm that yields to an accurate determination of the average velocity from the measurement of the surface velocity at a known flume.

RV7 works not only for the usual environmental monitoring; it is particularly suited to undertake urgent and difficult observation tasks. Incorporating with GDC controller and various types of level gauges, RV7 can be used as a cross-sectional area/velocity based flow meter for measuring flow rate of non-standard open channel and non-full pipe.

DV7 Doppler Velocity Sensor


The DV7 submersible velocity sensor is based on the principle of Doppler Effect; it exploits the latest IDSR (Intelligent Doppler Signal Recognition) technology and innovative engineering design.

The sensing elements are Doppler ultrasound twin 1 MHz piezoelectric crystals. The built-in electronic unit performs velocity calculation and outputs digital signal to a receiver like the Delta- Phase GDC. The receiver combines with level signal of a known flume cross section to provide corresponding Area/Velocity flow measurement for open channel and non-full pipe application without primary device. DV7 measures average velocity directly, no more tedious flow profiling work, and significantly reduces the cost of installation and operation for industrial and municipal wastewater pipeline applications provided that the liquid contains at least 50ppm with suspended solids larger than 30 micrometers.

Dissolved Oxygen


The DO7 sensor is based on luminescent optical technology. The Sensor is approved by the ASTM international Method D888-05. Without calibration requirements and thanks to an ultra-low power technology, the DO7 sensor meets the demands of field works and short or long term campaigns.

Without oxygen consumption, this technology allows you an accurate measure in all situations and especially in very low oxygen concentrations.

The Intelligent DO7 sensor stores calibration and history data within the sensor. This allows you a “plug and play” system without re-calibration. Thanks to the Universal Modbus RS485 protocol, the DO7 sensor can be connected to all devices commonly used (Data logger, GDC, Automat, Remote System…).

Chlorine Sensor


The FC7 is a panel mounted, ready to use Free Chlorine Sensor. It is designed to monitor free chlorine in drinking water, rinse water, cooling water or other fresh water samples from 0.05~10ppm Cl2 as the standard range or 0.01~5.00ppm with the low range sensor. The FC7 is compliant with EPA method 334.0 for measuring drinking water.Free chlorine exists in solution as pH dependent ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). Free Chlorine is the sum of the Hypochlorous acid and Hypochlorite ion in the sample. The Free Chlorine Sensor measures only the hypochlorous acid component of the free chlorine and the analyzer calculates the balance using either the measured or a user defined fixed value. The use of the pH sensor provides accurate compensation for samples between pH 6 and pH 9.5 and eliminates the need for an expensive sample conditioning system to control the pH of the solution.

Turbidity & SS


The TS7 Sensor consists of a light source and a light detector (photo detector). Incident light is scattered by the particles in the sample, and the scattered light is measured by the detector. The amount of scattering depends on the amount of material in the sample, the wavelength of light used and the size and composition of the suspended particles. The Sensor uses a long life near infrared LED (880nm) and the 90° scattered light method in accordance with ISO 1027/EN 27027 to assure accurate turbidity values.

An automated mechanical wiper is available to remain surface clean and remove air bubbles of the optical window in order to maximize the accuracy and minimize the maintenance requirement.

Turbidity is expressed in nephology-metric units (NTU), which are based on the light-scattering properties of a standardized formazin polymer solution.

SA-9 Spectra-Analyzer


SA-9 spectrometer probes use standardized spectral algorithms taking in to account the complete absorption spectrum of the water (200 - 750 nm in case of UV/Vis probe) for determination of organic sum parameters such as COD, TOC, BOB and DOC. Furthermore, SA-9's spectral compensation for light absorbing particles and turbidity provides a unique method that allows the monitoring of dissolved organic substances without the need for sample pre-treatment.

The validated spectral calibrations, that use multiple wavelengths for monitoring of each parameter, allow much more accurate and robust measurements than with where single wavelength measurement.

Using field special calibrations, it is even possible to distinguish various fractions of organic carbon groups using specific features of the absorption spectrum. In particular relations between particular parts of the spectrum and (bio) degradability or organic substances have been established. Such relations allow optimization of the treatment processes used to reduce organic contaminations, for example biological processes in waste water treatment plants. In this latter case, optimization is made possible by the on-line monitoring of the amount of organic substances that can be degraded by micro-organisms (BOD). Using this knowledge, the amount of waste that is fed into the treatment plant can be managed in such a way that the activated sludge is able to most efficiently reduce the organics or alternatively nutrient dosing can be controlled which ensures an optimal concentration at all times (no under or over-dosing).

Universal Transmitter

A plug and play function can be expected for those sensors in our recommended list, that means if you plug an intelligent sensor into a GDC and it will automatically configure to any of the listed measurements. GDC terminals can be expanded to work with any sensors with analogue or digital outputs for customized configuration.
