Flow Monitor is a device that is used in the tertiary treatment of wastewater to measure the flow of water or wastewater. It is a vital component in the monitoring and control of the treatment process. The flow monitor typically consists of a sensor or probe that is placed in the flow channel or pipeline and is capable of detecting the velocity of the water.
The sensor or probe generates a signal that is transmitted to a flow meter or controller, which calculates the flow rate and displays it on a digital readout or graph. Flow monitors can be used in a variety of applications in tertiary treatment, including monitoring the flow of effluent from settling tanks or clarifiers, measuring the flow of water through filtration or disinfection systems, and monitoring the flow of water through aeration systems.
Flow monitors can also be used in conjunction with other monitoring devices, such as dissolved oxygen sensors, to provide a more comprehensive picture of the treatment process. There are several types of flow monitors available, including ultrasonic, electromagnetic, and mechanical flow meters. The type of flow monitor selected depends on the specific application, as well as factors such as the size of the flow channel, the flow rate, and the type of fluid being measured.
