Article about water quality alert

Water is the most precious source of our well being. In water are many substances we admire and many we do not like some of them even can harm human or animals.

Minerals, life microorganism, plants and bacteria’s can be found in water and smell and taste depend on them even if our individual sense is different. Authorities try hard to make water safe with all kind of different treatments biologically and chemically. Typical water sensors are chemical sensors and in touch with water like pH level, Dissolved oxygen, Ammonium, or Conductivity. For compliance with the water standards use certified laboratories    The high tech water sensor from Hohner Corp. measures physical properties with optics without being in touch with water. It is designed to show the smallest possible change in water quality.

 

Following optical properties are detected in this sensor

Color – sometimes invisible for a human eye

                But in many cases a contamination colors liquid

                The sensor measures blue green red and infrared

Clarity  – sometimes invisible for the human eye

                Tiny contamination’s can be detected by adding all color

                outputs

Refractive index

                Typically water has a refractive index of 1.33

                This index is typical for every fluid

Polarization

                In its natural state water has a polarization of zero degrees

                Alcohol has a typical polarity of 90 degrees

Fluorescence

                Many bacteriological contamination’s glow if lightened with

                UV light

Luminescence

                Many bacteriological contamination’s glow if lightened with

                UV light and keep on glowing over a period of time or forever

Rayleigh scattering

                Photons are elastically scattered

The emitted photon has the same wave length as the    absorbing photon

Raman effect

                Photons are inelastically scattered

    The emitted photon has the a different wave length as the

                absorbing photon

               

Calibration             The sensor is simply calibrated to destilled water and deviation

                                from this value is measured

Timing                    About 100 readings per sec

Output

REFRACTION XXX.X = max + / - 99.9 %

POLARIZATION XXX.X = max + / - 99.9 %

FLUORESCENCE XXX.X = max  + / - 99.9 %

COLORHIGH XXX.X = max + / - 99.9 %

COLORLOW XXX.X = max + / - 99.9 %

FLUORESCENCE XXX.X = max  + / - 99.9 %

TEMPERATURE XXX.X = max 100.0 degree C

 

Examples: Out of this values following alerts can be determined

                Chemical alert

                Bacteriological alert

                Algae alert

                Sweet alert

                Dirt alert

                Fuel alert

                Acid alert

Principle

Flashing lights and photodetectors are around a boro silicate glass cylinder and together with optical filters and masks the results are used in a microprocessor to calculate most important data to terminate physical quality of water.

The sensor is calibrated to 100 % pure distilled water and calculates deviation.

An 1 ¼ “ flange on in and output of the sensor allows also testing of waste water.

The sensor is made of food approved stainless steel.

The sensor is water proof and can be used down to 3ft under water.

Since this data’s are physical properties and therefore vary with ambient temperature we also measure temperature

Hohner Corp has a water sensor installed in Beamsville. This water sensor is connected to a GSM telephone modem. The telephone modem is ready available from many vendors like Nokia Motorola Siemens etc and has a SIM card. Any provider will assign a phone number to it. Power supply for water sensor and modem is pulled from modem batteries or line power.

To call on the quality of Beamsville water we offer 2 possibilities
