Application of Ultrasonic Liquid Flow Meter in Sewage

Wastewater treatment plant to receive industrial wastewater discharged by enterprises in the industrial park of the main pipe diameter is generally more than 600 mm, the water quality is turbid, complex composition, flow rate varies greatly. For this condition, the flow meter in the design selection, the requirements of measuring instruments with good corrosion resistance and large range ratio. Sewage flowmeter turbine flowmeter, electromagnetic flowmeter or orifice plate flowmeter, etc., but such flowmeter need to be installed in the pipeline sensor, pressure loss, easy to wear and tear, short life expectancy, vortex and velocity distribution sensitive. In practice, the sensor is often covered by debris or entangled and affect the normal use, can not provide accurate data.

As the flow measurement point of water intake main is far away from the monitoring center in the project, ultrasonic liquid flow meter is required to have many functions such as on-site display of instantaneous flow rate, cumulative flow rate, operating status, etc., historical data recording and storage, automatic data checking and inspection, diagnosis of operating conditions and fault alarms, etc., of which the most important one is the ability to transmit the signals to the monitoring center. The main thing is to be able to transmit the signal to the monitoring center. Comprehensive practical needs, the design of the ultrasonic liquid flow meter using RS485 interface MODBUS protocol, master-slave Q&A mode will be collected signals uploaded to the monitoring center control station in communication mode.

Ultrasonic Liquid Flow Meter

Insertion type Magnetic Flow Meter

Our technicians visited the wastewater treatment plant, and after field investigation, we finally helped the customer to select ultrasonic liquid flow meter and insertion electromagnetic flow meter, which solved the limitation difficulties of the project. It has the advantages of high accuracy, large measuring range, no head loss, easy installation and so on, which solves the problem of precise measurement.
