Photoelectric sand analyzer

1、Photoelectric sand analyzer Product Introduction

Photoelectric sand analyzer utilizes the principle of light scattering to measure suspended sediment in rivers, with a measurement range of 0–20,000 g/L.Photoelectric sand analyzer consists of a sensor, data acquisition unit, IoT transmission module, solar power system, pole support, floating body in water, and cloud platform.

The sediment concentration sensor utilizes the principle of light scattering to accurately measure the sediment content of water.This system is suitable for precise measurement of sediment content in rivers, canals, and waterways.It is compact, easy to operate and maintain, and enables real-time online monitoring and measurement of sediment.

2、Photoelectric sand analyzer Product Features

1.The sediment content sensor is made of stainless steel, which is corrosion-resistant and pollution-resistant.A self-cleaning brush at the bottom allows for regular cleaning, ensuring accurate data.

2.Equipped with a low-power data acquisition unit, consuming as little as 50mA at 12V.

3.Built-in 3-year data allowance; customers can choose to recharge within one year of expiration.

4.The 30W solar panel's recessed design on the top cover improves photoelectric conversion efficiency and increases wind resistance.The solar charging controller uses MPPT (Automatic Power Point Tracking), improving efficiency by 20%.

5.The integrated 1.5-meter-high bracket facilitates transportation.The bracket is coated with anti-rust paint, resulting in a beautiful finish and significantly enhanced corrosion resistance.The protective case is made of stainless steel, which is corrosion-resistant, oxidation-resistant, and has an IP66 waterproof rating.The float is compact and flexible in installation, supporting future expansion with multiple water quality sensors.The float is equipped with a steel cable for wind and tipping prevention.

6.The cloud platform has an SMS alarm function; an SMS message is sent to a designated mobile phone when limits are exceeded.One account can be used to check whether multiple devices have exceeded the limit at the same time.

4、Photoelectric sand analyzer Cloud Platform Introduction

1.The cloud platform displays the online status of all devices under the current user.

2.The cloud platform displays the weather conditions for the current device's location, including location, time, weather, temperature, wind speed, and wind direction.

3.The cloud platform allows viewing real-time data, displaying the latest telemetry data for all parameters.

4.The cloud platform allows viewing historical data.Selecting a specific parameter and time period displays a line graph of that parameter within the selected time period, and allows exporting filtered historical data.

5.The cloud platform allows setting threshold alarms.When a threshold is set by the customer, if a parameter falls outside the threshold range, an alarm message for that parameter on a specific device is displayed in real-time, accompanied by an audible alert.

6.The cloud platform has a location function.When the customer provides the latitude and longitude of the device, its location can be marked on a map.

7.The cloud platform has a monitoring function.After binding a camera to the device, the device can be monitored through the cloud platform.

8.In addition to being displayed on a large computer screen, the cloud platform allows data to be viewed anytime, anywhere via a mobile browser.

9.The cloud platform has an SMS alert function, which can send SMS messages to designated mobile phones when devices are outside the threshold range.Under one account, multiple devices can be monitored simultaneously to see if they exceed or fall below the threshold.

10.The cloud platform has a WeChat alert function.After the account is linked to a WeChat account, a message is sent to the service account when devices are outside the threshold range.
