Digital constant voltage residual chlorine sensor, based on the constant voltage principle, measures the residual chlorine content in water. A stable potential is applied between the polarization electrode and the reference electrode. Different components to be measured generate different current intensities under this potential. The concentration of the measured component is calculated by analyzing the current signal. The residual chlorine sensor has a simple structure and is easy to clean and replace. At the same time, the membrane and reagent do not need to be replaced during the use of the electrode. The maintenance is simple, ensuring the stability, reliability and accuracy of the instrument for long-term operation. The sensor outputs a standard RS485 (Modbus/RTU protocol) digital signal.

It is used for water quality detection in production processes such as calcium/magnesium hardness detection in boiler softening water, environmental protection, civil water, industrial water and treatment, and sewage discharge.

Fire hydrant anti-theft water remote sensing terminal/fire hydrant intelligent alarm modification device, directly replaces the fire hydrant water outlet cover, transforms ordinary fire hydrants into intelligent fire hydrants, remotely monitors the water outlet, location, and status of fire hydrants in real time, and automatically reports the alarm when the fire hydrant is damaged or water is stolen. Working mechanism: The fire hydrant outlet generally has two diameters of 65mm and 100mm. When the 65mm outlet outlet discharges water, the water pressure in the fire hydrant triggers the float switch in the device after the water is discharged, and the alarm is immediately reported; when the 100mm outlet outlet uses water, when the alarm device is turned, the tilt switch in the product is triggered, and the alarm is immediately reported.

Intelligent fire hydrants/water hydrants realize water card metering and support prepaid and postpaid charging methods. It standardizes the water order of municipal garden and environmental protection water use departments, effectively curbs the phenomenon of fire hydrants stealing water, and plays a significant role in reducing the production and sales gap of water companies. It realizes fixed-point water collection, metering and charging, and remote supervision for urban ecological water use such as gardening, road spraying, and sanitation. It can timely detect situations such as fire hydrant knockdown/damage.
