How turbidity measurement works using an optical 90° scattered light probe

Water turbidity is a parameter that indicates the amount of suspended solid particles (sludge, colloids, bacteria, oxides, organic matter) that make the water cloudy. The higher the turbidity, the lower the water clarity and the higher the concentration of suspended solids. The S461 ST turbidity sensor uses the 90° scattered light optical principle (nephelometry), which is today one of the most reliable technologies for measuring turbidity in process water, wells, surface water and wastewater.

Measurement principle: 90° scattered light

Inside the probe there are:

A LED light source that emits a stable light beam, A photodetector positioned at 90° to the light beam

When the water is clear, the light passes through it with very little deviation.

When suspended particles are present, they intercept the light and scatter it in all directions. A portion of this scattered light reaches the detector located at 90°. The more particles are present, the stronger the scattered light signal becomes. This signal is converted into a turbidity value expressed in NTU (Nephelometric Turbidity Units). 

Why the 90° geometry is so reliable, The 90° detector position allows the sensor to:

Exclude the direct transmitted light, minimize the influence of water color, measure only the light actually scattered by suspended particles, this makes the measurement stable and accurate even in dark, colored or heavily polluted water. 

Importance of proper installation geometry

For accurate measurement, the optical window of the probe must face a free and unobstructed measurement volume. 

As shown in the illustration:

At least 5 cm (2 in) of free space must be maintained in front of the optical cone

At least 10 cm (4 in) distance must be kept from walls, tank bottoms or pipe surfaces

This prevents:

Optical reflections, False high turbidity readings, Signal instability, Signal conversion and process control

The probe converts the scattered light intensity into a 4–20 mA output signal, which can be connected to: 

Controllers

PLCs, Data loggers, SCADA systems, This allows turbidity to be:

Continuously monitored

Used to control filters, backwash cycles or chemical dosing. Logged for process optimization and regulatory compliance.

Technical conclusion

The 90° optical turbidity measurement principle used by the S461 ST probe provides reliable and repeatable monitoring of water quality, even in demanding applications such as wastewater, well water and industrial process water.

Correct mechanical installation and proper optical geometry are essential to turn the sensor into a truly effective process control instrument.

👉 In water treatment systems, turbidity is not just a number: it is one of the earliest indicators of contamination, process instability and filtration problems.

Kontrol 40 - single-parameter control instrument

The Kontrol 40 range is designed to ensure maximum safety, user-friendliness and ease of installation for the end user; it is made so that the maintenance of the electronic circuits is as simple as possible without having to reconfigure all the electrical connections. The instruments are available in four different formats:

• For mounting on DIN BAR - IP40

• 48 x 96 mm format for panel mounting - IP40

• 96 x 96 mm format for panel mounting - Front IP65 / Rear IP20

• 144 x 144 mm format in airtight box for wall mounting - IP65

All models have two normally-open relays that can be managed and activated when two independent thresholds are exceeded, as well as a programmable 4 - 20 mA analogue output. A self-explanatory and easy-to-read menu guides the operator step by step in configuring the device, making programming quick and simple.A statistical menu displays the number of activations performed by the two

relays, as well as the number of alarm conditions encountered and the number of pause signals received (input reed signal).

Side Channel Blowers

The side channel blower is an electromechanical machine used for air handling in low-flow, medium-pressure applications, both in blowing and suction modes. Thanks to the side channel operating principle, it ensures continuous, pulsation-free operation with minimal maintenance requirements.

The air filter, installed on the suction side, protects the blower from dust and solid particles, preserving the integrity of the impeller and increasing the reliability and service life of the unit, especially in industrial or harsh environments. 

The safety valve is a key protective device for the system: it automatically intervenes in the event of excessive overpressure or vacuum, preventing mechanical overloads and damage to the blower. Its presence ensures safe operation and compliance with good engineering practice. 

👉 Final note for professionals: correct selection and installation of the blower, air filter, and safety valve are essential to guarantee consistent performance, operational safety, and long service life of the system.

DEBATTERIZZATORI DOMESTICI A RAGGI UV

Il debatterizzatore ad uso domestico è un dispositivo progettato per la riduzione della carica batterica presente nell’acqua destinata al consumo umano. Viene normalmente installato a valle dei sistemi di filtrazione e trattamento (addolcitore, filtri a carbone attivo, microfiltrazione) e rappresenta una barriera di sicurezza finale prima della distribuzione dell’acqua ai punti di utilizzo.

Il principio di funzionamento più diffuso in ambito domestico è basato sulla disinfezione mediante raggi UV-C. L’acqua attraversa una camera in acciaio inox all’interno della quale è presente una lampada UV che emette radiazioni a lunghezza d’onda germicida. Questa radiazione inattiva microrganismi come batteri, virus e protozoi, impedendone la riproduzione, senza alterare le caratteristiche chimico-fisiche dell’acqua.

Ambiti di utilizzo

Il debatterizzatore domestico trova applicazione in:

• abitazioni alimentate da pozzi privati

• case di villeggiatura con utilizzo discontinuo dell’impianto

• impianti idrici soggetti a ristagni o basse portate

• integrazione di sistemi di trattamento acqua già esistenti

È particolarmente indicato come protezione preventiva contro contaminazioni microbiologiche accidentali.

Vantaggi principali

• disinfezione senza utilizzo di prodotti chimici

• nessuna modifica di gusto, odore o composizione dell’acqua

• funzionamento continuo e automatico

• manutenzione semplice (sostituzione periodica della lampada UV)

• elevato livello di sicurezza igienico-sanitaria

Indicazioni per una corretta installazione

Per garantire l’efficacia del trattamento è fondamentale che l’acqua in ingresso sia limpida e priva di torbidità, motivo per cui è sempre consigliata l’installazione di un prefiltro meccanico. Inoltre, il corretto dimensionamento in base alla portata e il rispetto dei tempi di contatto UV sono elementi essenziali per assicurare una disinfezione efficace.

---

In conclusione, il debatterizzatore ad uso domestico rappresenta una soluzione affidabile e tecnicamente consolidata per migliorare la sicurezza microbiologica dell’acqua. Un’installazione corretta e una manutenzione regolare sono aspetti fondamentali per ottenere prestazioni costanti nel tempo e garantire la protezione dell’impianto e degli utenti finali.

Pompa di dosaggio SEKO TEKNA TCK (pompa dosatrice elettromagnetica temporizzata)

Principio di dosaggio

La pompa non dosa “a richiesta” ma secondo un programma temporale:

1. Impostazione del timer: si programma una sequenza temporale settimanale (es. orari e giorni della settimana in cui attivare il dosaggio). Puoi settare fino a 10 eventi di dosaggio a settimana. 

2. Attivazione temporizzata: quando arriva l’ora programmata, la pompa si avvia e inizia a erogare il prodotto chimico. 

3. Costanza della portata: durante l’erogazione, la pompa dosa con flusso costante corrispondente al modello scelto (litri/ora), determinato dal numero di corsi al minuto e dal volume per corsa. 

   ➤ Esempio semplice: se hai programmato un dosaggio settimanale ogni lunedì alle 08:00 per 5 minuti, la pompa si avvierà a quell’ora e erogherà quantità di liquido in funzione della portata dichiarata (es. 10 l/h se configurata così). Dopo i 5 minuti si ferma fino alla prossima programmazione.

🔹 Componenti chiave del dosaggio

• Timer programmabile settimanale → decide quando erogare. 

• Portata costante → definisce quanto dosa in un determinato tempo. 

• Membrana elettromagnetica → crea il flusso dosato tramite corsa alternata controllata. 

🔹 Riassumendo in termini operativi

✔ Programmi gli eventi di dosaggio sul timer (giorni/ore)

✔ La pompa si avvia automaticamente nei momenti impostati

✔ Eroga il prodotto in modo misurabile e ripetibile, basato sulla portata del modello
