Product Introduction
Products Description
The DPLLS series dual channel ultrasonic flowmeter adopts a dual channel ultrasonic flow measurement product using American PhoTime technology, overcoming the shortcomings of single channel ultrasonic flowmeters that are not suitable for flow field changes, low accuracy, and unstable flow. The measurement principle is based on the delay method measurement. Due to the optimized design of using two sound channels, this ultrasonic flowmeter greatly overcomes the influence of turbulence randomness on measurement, greatly improving the adaptability and measurement accuracy for different working conditions. The use of ultrasonic flowmeter for measuring small flow is more guaranteed. It can be used as a quantitative control measurement standard.

| Features |
- Supports both mono and dual channels, and when one channel is abnormal or not connected, it can automatically switch to a mono operation based on signal quality;
- Using the latest 32-bit Cortex-M4 core CPU as the processor core, using 64-bit floating point operations, calculations do not lose accuracy;
- It uses high-speed ADC to collect ultrasonic signals, and has ultrasonic waveform restoration and reconstruction technology; it uses a precision time measurement chip, and the ultrasonic propagation time accuracy can reach 22 picoseconds;
- Single board and full patch technology are all welded using SMT machines, which greatly reduces problems such as virtual soldering, missing soldering, and short circuits on the circuit board;
- Heat function: Optional PT100 external clip-on platinum resistor can realize heat measurement.
