Name：Clamp-on Ultrasonic Heat Meter
Model：LRF-3000SW-R
Size：210*160*63mm
General Introduction:
LRF-3000SW-R is a clamp-on ultrasonic heat meter, which is composed of wall-mount transmitter, clamp-on flow transducers, RTD module and clamp-on temperature probes . It adopts our self-developed TGA measurement technology. Compared with the commonly used TDC calculation method used by most of our domestic manufacturers ,TGA measurement technology is an algorithm for measuring process time with higher speed and accuracy.
Features:
Compared with other conventional flow/heat meters, LRF-3000S has other unique features besides the common features such as high flexibility of field installation, high response speed and better measurement ability under low flow rate:
1. Adopts high performance FPGA chip with independent 400,000 gate array. Measurement rate can be more than 300 times per second, which greatly improves the tolerance rate of bubbles in the measured pipe compared with other brands. It can withstand continuous bubbles for up to 5 seconds.

2. Increased signal strength has greater penetration ability to all kinds of scale, rust and pipe lining.
3. 4 lines dot matrix LCD screen. Chinese/English menu selectable. Easy to be operated.
4. Transducers adopt our special manufacturing process and matching technology. Zero-point range can be controlled within 0.03m/s. Time difference between each pair of static sensors is less than 2 nanoseconds, which effectively ensures the authenticity of the measured time difference.
