The multi-channel plug-in ultrasonic flow meter is a meter that measures the liquid flow in a closed circular pipe based on the "cross-correlation time difference method" as the basic measurement principle. It uses advanced multi-channel signal acquisition and processing technology, has a number of patents, uses high-performance ultrasonic sensors, combines the advantages of a mono ultrasonic flow meter, and has high flow measurement accuracy, good stability, and anti-interference capabilities. Strong, good fluidity and other characteristics.
Multi-channel signal acquisition and processing technology
Compared with the mono channel, the multi-channel ultrasonic flowmeter measures the flow state of the medium in the pipeline through multiple channels distributed in the pipeline, which reduces the influence of the measurement on the flow field in the pipeline and effectively improves the whole machine. Repeatability and measurement accuracy
High real-time performance and fast response speed
YYC-M multi-channel ultrasonic flowmeter adopts time difference method to measure pipeline flow. Ultra-high-precision measurement of ultrasonic transmission time more than 500 times per second, high dynamic flow measurement, real-time signal processing, fast response to changes in flow rate
Multiple output functions
Current, frequency, pulse and relay output functions, RS485, HART communication interface
Built-in heat measurement function
It can collect the temperature difference and calculate the heat through an external pair of PT1000 platinum resistors.
Lightning protection output interface
Circuit protection for current output, frequency output and RS485 communication port
Data security during power outages
The data is stored in EEPROM, which can realize automatic storage. The measurement and calculation data storage protection is safe and reliable.
