DISSOLVED OXYGEN (DO) MONITOR (MODEL-1)

Overview

Determination of dissolved oxygen (DO) is important in various industries. In nuclear power plants the specification of DO concentration in coolant circuit is less than 7 ppb. It is also important to monitor DO in industrial waste, sewage and water bodies. BARC has developed DO monitor which has wide linear dynamic range, suitable for the determination of DO at ppb concentration range for various industrial applications.

INTRODUCTION

Determination of dissolved oxygen is important in various industries. It requires continuous monitoring to keep the corrosion of the structural material under control and thus to improve the life of the chemical plants. In nuclear power plants the specification of DO concentration in coolant circuit is less than 7 ppb. Determination of the dissolved oxygen is also important in industrial waste, sewage and water bodies. Determination of dissolved oxygen in potable water is an important water quality parameter. Present model has been designed for the continuous monitoring of dissolved oxygen under flow condition

The working principle is based on the redox coupling of two metals with difference in redox properties. The reduction current of oxygen is the measurable parameter for the determination of dissolved oxygen. The current flow due to this process is measured using the electronics device and the measured current is calibrated with respect to the dissolved oxygen concentration. Sensor displays the reading of dissolved oxygen concentration in ppm/ppb units

ADVANTAGES

The sensor is based on the indigenously developed technology and locally available materials.
Battery operated, portable and tolerant to electrical noise and moisture.
The unit has been designed using intrusion proof (IP66) aluminum enclosure & intrusion proof (IP67) switches & connectors with inbuilt rechargeable battery and integrated low power LCD panel meter for uninterrupted operation.
Technical parameters: Dynamic range 1 ppb to 20 ppm; Resolution 0.1 ppb at 2 ppm range; Aqueous medium, Working temperature 10 to 80 °C.
Good market potential of such sensor in various industries with requirements of continuous monitoring of dissolved oxygen.
Unit can be manufactured at lower cost compared to the imported items.

APPLICATION

Determination of DO in nuclear power plants and other chemical plants at ppb concentration range for continuous and in batch mode of operation under flow conditions
The unit is also suitable for the determination of DO at ppm concentration in feed water, treated sewage water and potable water under flow condition.
