The sewage flow monitoring device is an important device for measuring and monitoring sewage flow. It is of great significance for the management of sewage treatment systems and environmental protection. The following is a detailed answer about the sewage flow monitoring device:
1. Device type
The sewage flow monitoring device mainly includes the following types:
Electromagnetic flowmeter: Based on Faraday's law of electromagnetic induction, the flow rate is calculated by measuring the change in conductivity in sewage. Electromagnetic flowmeters have the advantages of high measurement accuracy, good stability, and a wide range of applications, and are suitable for various sewage measurement scenarios. Depending on the pipe diameter and medium characteristics, you can choose a pipe segment or insertion type electromagnetic flowmeter.
Ultrasonic flowmeter: The flow rate is measured by using the difference in the propagation speed of ultrasonic signals in sewage. Ultrasonic flowmeters are divided into external clamp type and insertion type, with the characteristics of easy installation, non-contact measurement, and high measurement accuracy. It is particularly suitable for the measurement of large-diameter pipelines and corrosive media.
Turbine flowmeter: The flow rate is calculated by measuring the rotation speed of the turbine blades in the sewage. The turbine flowmeter has the advantages of simple structure and wide measurement range, but it is easily affected by impurities and requires regular cleaning and maintenance.
Open channel flowmeter: Suitable for open channel flow measurement with free surface, such as drainage ditches, etc. The open channel flowmeter is combined with ultrasonic level meter for flow measurement, which has the advantages of large measurement range and little influence from tributary surface backwater.
2. Selection and installation
When selecting a sewage flow monitoring device, the following factors need to be considered:
Measurement principle: Select a suitable measurement principle according to actual needs, such as electromagnetic, ultrasonic, turbine, etc.
Installation conditions: Consider installation requirements such as pipe diameter, fluid flow direction, and straight pipe length to ensure the accuracy and reliability of the flow meter.
Range and accuracy: Select a suitable range and accuracy according to actual needs to meet measurement requirements.
After-sales service: Select a manufacturer with good after-sales service to ensure that the equipment can be repaired and maintained in time when a failure occurs.
When installing a sewage flow meter monitoring device, the following steps need to be followed:
Choose a suitable location for installation to ensure that there are no obstacles between the flow meter and the pipeline. Connect the sensor to the pipeline and ensure that the connection is tight to prevent the sensor from being washed away by the water flow. Set parameters, including pipe diameter, fluid type, sensor location, etc. Calibrate to ensure that the measurement results of the flow meter are consistent with the actual flow. Start flow measurement and analyze and manage the measurement data.
In summary, sewage flow monitoring devices play an important role and function in sewage treatment systems. Selecting appropriate sewage flow monitoring devices and installing and using them correctly are of great significance to improving sewage treatment efficiency and protecting the environment.
