- Low Cost Ultrasonic Flow meter/Heat Meter



The low cost ultrasonic flow meter is developed on the latest innovation from Abest Technology since 2008. The low cost flowmeter employs cutting-edge technologies by using ultrasonic transit-time measurement, digital signal processing and surface mounting electronics.

The low cost flowmeter also provides abundant capabilities for accurate liquid flow measurement from outside of a pipe. The proprietary signal quality tracking and self-adapting techniques allow the system to optimally adapt to different pipe materials automatically.

With flow local keys,the ultrasonic flowmeter provides traditional operation ways for setting all parameters,including inputting value. As is known, electromagnetic flow meters usually have 4 keys for local operation.

This type ultrasonic flowmeter can be equipped with an optional key board module. The users can either use the RS-485 interface or the display / keyboard interface to program the flowmeter. The transducer installation is also simple and no special skills or tools are required.
Due to the non-intrusive nature of the clamp-on technology, there is no pressure drop, no moving parts, no leaks, no risk of contamination, no risk of corrosion, no pressure dependency. This type ultrasonic flow meter is designed for large quantity, low cost applications. Its unique features, particularly very low cost, very high performance and very small size, make it the ideal choice for industrial automation, processing control, water source management, flow meter networking and OEM applications.
