FA7-CP Chlorophyll sensor uses fluorescence to measure phycocyanin inside chlorophyll and its derived substances in water. The content of chlorophyll is calculated by the released fluorescence energy when excited by a high-energy LED light source.
FA7-CP sensor emits a LED light beam of 470nm through water; It excites chlorophyll in water to produce fluorescence with a specific wavelength which is then employed to measure the concentration of chlorophyll.
FA7-CP sensor is particularly suitable for scientific research as well as for online water quality monitoring of ground water, surface water and other water applications.
FA7 series of fluorometer sensors are designed for water quality measurements based on UV to visible fluorescence spectroscopy. FDOM (Fluorescent Dissolved Organic Matter) are primarily anthropogenic sources of hydrocarbons (for example, mineral oils, pesticides, herbicides, and fungicides). FDOM is a subset of Total Organic Carbon (TOC) compounds which also include naturally occurring fulvic and humic acids derived from decaying plant debris. Some of the compounds that contribute to the TOC pool also fluoresce. In the literature it is common to refer to the fluorescent part of the TOC as FDOM. Although FDOM is composed of both natural and man-made substances, the complex cyclic molecules contained in fungicides, pesticides, and herbicides tend to fluoresce far more brightly than the simpler, straight-chain natural substances found in plant debris. The FA7-FM is a highly sensitive sensor for detection of very low concentrations (on the order of micrograms per liter) of FDOM. It may be used to detect oil-in-water if mineral oil is the main component. The sensor may be connected to a GDC terminal enabling both stationary use (shafts, flows or piping) and mobile use. An optional clamp-on wiper for automatic cleaning of the optical window minimizes the maintenance downtime.
FA7-BA Cyanobacteria (Blue-green Algae) sensor uses fluorescence approach to measure cyanobacteria concentrations in water. When cyanobacteria are excited by a high-energy LED light source of 590nm, it produces a specific wavelength fluorescence which based on its spectrum absorption characteristics, can be used to detect cyanobacteria concentrations in water.
FA7-BA sensor is particularly suitable for scientific research as well as for online water quality monitoring of ground water, surface water and other water applications.
FA-7 is a new generation of immersion sensors for measurement of oil or hydrocarbons in water based on the UV fluorescence principle. When excited by a light beam at a specific wavelength, some compounds re-emit light at a longer wavelength. Since there are very limited number of chemicals such as PAH that have fluorescence signatures, this method gives a highly selective measurement with much higher sensitivity than the conventionally used infrared-based technology. This makes it possible to determine even the slightest traces of PAH's. The FA7 sensor connects to a GDC enabling both stationary use (shafts, flows or piping) and mobile use. An optional clamp-on wiper for automatic cleaning of the optical window minimizes maintenance downtime.
SA-9 is the new generation of immersion spectra analyzing sensor. It uses standardized spectra algorithms by taking the complete 200 to 710 nm absorption spectrum of water into account to determine the nitrogen and carbon compounds. SA-9's spectrum compensation for light absorbing particles and turbidity provides a unique and high sensitivity approach that allows the monitoring of dissolved organic substances without sample pre-treatment. SA-9 gives reliable readings for NO3-N, NO2-N, organic ingredients (CODeq, BODeq, DOCeq, TOCeq), and a number of other parameters. The sensor can be submerged into water by mounting hardware or using flow cell for bypass installation. Measurement path length is from 0.5 to 35 mm. There is a built-in purging nozzle for cleaning the test window by compressed air or pressurized water stream. There is also an optional clamp-on wiper for automatic test window cleaning.
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.

The DG7-FCO free chlorine sensor (non-reagent type) is used for measuring concentration of free chlorine present in sample water, such as chlorine (Cl2) hypochlorous acid (HClO), and hypochlorite ion (ClO-).
Total Chlorine is defined as the total combined amount of Free Chlorine, Chloramine, Organic and Bound Chlorine in the sample. The DG7-TC is designed to monitor Total Chlorine in drinking water, rinse water, cooling water or other fresh water samples.
DG7-TC has two ranges to choose from: High Range 0.05 to 20 ppm Cl2 and Low Range 0.005 to 2.000 ppm. The sensor significantly reduces pH dependence such that there is no need of PH compensation for most applications.
The DG7-OZ is a panel-mount, ready-to-use dissolved Ozone (O3) sensor. It provides several measurement ranges to accommodate various applications: 0 ~ 2.00 ppm for disinfection and 0 ~ 10.00 ppm for oxidation and bleaching. Ozone is a colorless to pale blue gas, when in low concentrations; it gives off an irritating acidic odor. Ozone is a strong oxidizer, stronger than chlorine and chlorine dioxide. It reacts quickly, disintegrates into oxygen gas, and increases the amount of oxygen in water when applied to water treatment.

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. It outputs velocity value by employing the frequency shift between a transmitting ultrasonic wave and its echo caused by suspended particles or gas bubbles (discontinuities) in motion. 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. The 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.

RV7 is a non-contact 24.125/24.200 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 Delta-Phase’s 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.
