1. Introduction
In modern industrial processes, accurately and reliably measuring the flow of fluids containing impurities, bubbles, or suspended solids has always been a challenge. As a professional Wastewater Flow Meter, the DF6100-EP Portable Doppler Ultrasonic Flow Meter produced by Lanry Instruments is specifically designed to tackle such complex working conditions.
Series DF6100-EP Non-Invasive Doppler Ultrasonic Flow Meter is designed to measure volumetric flow of within closed conduit, the pipe line must be full of liquids, and there must be a certain amount of air bubbles or suspended solids in liquid.The Doppler ultrasonic flow meter can display flow rate and flow totalizer, etc., and is configured with 4-20mA, OCT outputs.
2. Core Measurement Principle
As a typical Wastewater Doppler Flow Meter, the DF6100-EP High Precision Flow Measurement operates on the Doppler Effect principle. The flow meter operates by transmitting an ultrasonic sound from its transmitting transducer, the sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the receiving transducer. If the sonic reflectors are moving within the sound transmission path, sound waves will be reflected at a frequency shifted from the transmitted frequency. The shift in frequency will be directly related to the speed of the moving particle or bubble. This shift in frequency is interpreted by the instrument and converted to various user defined measuring units.
This operating principle further consolidates its advantage as a Flow Meter for Dirty Liquids, making the meter ideal for dirty or aerated liquids, but unsuitable for clean fluids like tap water that lack sufficient reflectors. Clean fluids are suitable for Transit-Time Ultrasonic Flowmeters.
3. Wide Range of Applications
Thanks to its unique working principle, the Portable Doppler Flow Meter DF6100-EP excels in many applications where traditional flow meters struggle, including:
Water and Wastewater Treatment: It is the preferred solution for measuring raw sewage, return activated sludge, waste activated sludge, and internal plant drainage flows, fully demonstrating its value as a specialized Flow Meter for Dirty Liquids.
Industrial Processes: Suitable for measuring pulp, ore slurry, chemical slurries mixed liquids.
Circulation Systems: As a flexible Portable on Doppler Flow Meter, it provides reliable flow monitoring in recirculating water and cooling water systems in industries such as mining and metallurgy, even when the water contains significant impurities.
Other Fields: Also applicable for measuring groundwater extraction, animal processing wastewater, and other fluids containing solid components, further expanding the application scope of Non-invasive Flow Measurement technology.
5. In summary
The DF6100-EP Non-Invasive Doppler Ultrasonic Flow Meter, as a professional Wastewater Flow Meter, ingeniously applies physical principles and Non-invasive Flow Measurement technology to transform complex fluid measurement into precise electrical signals. Whether as a Flow Meter for Dirty Liquids or a flexible Portable Doppler Flow Meter, it provides a powerful, economical, and reliable flow monitoring tool for various industries dealing with complex fluids.
