How does a Flow Sensor Work?
A flow sensor features a plastic valve and a fluid rotor with a hall effect. The hall effect sensor plays a major role in the overall working of a flow sensor. For example, when the fluid flows through a plastic valve, the rotor starts rotating and changes the speed of the motor. The changing speed of the motor generates a pulse signal which is measured by the Hall Effect sensor. This is how a flow sensor measures the flow of water or any other liquid.
Applications of Flow Sensors in Water and Wastewater Treatment Industries
Many of our flow sensor models are used in various drinking water production and distribution systems and collection and recovery systems. The following are a few common applications of flow sensors in water treatment applications.
- Water acquisition: Flow sensors are used for managing the surface and ground level water intake for proper pump operation.
- Water filtration and clarification: Water flow is monitored using flow sensors to adjust the delivery of coagulants for water filtration. Consistent flow measurement also helps set effective backwash filtration cycles.
- Water treatment and disinfection: Water treatment and disinfection are performed in both the water and wastewater treatment industries. Disinfectants, fluoride, corrosion inhibitors, and pH adjustment chemicals are added to improve water quality. In addition, the flow sensors are used to measure the flow of liquids to ensure the correct dosage disbursement.
- Water Delivery: Water delivery is measured by city water resources or water authorities for various reasons. This is achieved using various types of flow sensors.
The following are a few common applications of flow sensors in wastewater treatment applications.
Collection: This is the first step in the water recovery process, where the water flow from lift stations and sewage flow is measured using flow meters. This flow measurement is performed to determine the quality of water being pumped.
Aeration: Aeration basins are commonly used in wastewater treatment plants to grow microorganisms that treat wastewater. Flow sensors are used to measure the flow of air that helps maintain a proper aeration stage.
Dosage: Wastewater is treated using various chemicals before being released into the water sources. This treatment is usually done using chemicals like pH adjusters, dechlorinating agents, chlorine, and so on. Flow sensors are used to measure corrosive chemicals and compensate for the change in pressure due to fluctuating levels of chemicals in the tank.
Discharge: Monitoring the flow of water discharge is necessary to ensure compliance with regulatory laws.
