Name:Fixed-clamp-on Ultrasonic Flow Meter
Model:LRF-2000SW


General Introduction:
LRF-2000S is one of the best-selling flow meters. It enjoys high popularity because of its economical price and reliable function. Installation is quite easy and operation is convenient.


Features:
High Accuracy measuring 
Linearity: better than 0.5%, Repeatability: better than 0.2%, Accuracy: better than ±1% 
Wide Measuring Range 
Several types transducer for selection, measuring pipe size from DN32mm to DN6000mm
Chinese or English menu 
Different version UFM can support Chinese or English display, easy to operate
High Reliability 
Adopt low voltage, multi-pulse technology to improve accuracy, useful life and reliability
Strong Anti-interference 
Dual-balance signal differential receiver/driver circuit to avoid interference of converter, TV tower, high voltage line etc.
Powerful Recording Function 
Automatically record the following data: 1. The totalizer data of the last 512 days/128 months/5 years 2. The time and corresponding flow meter of the last 64 times of power on and off events 3. The working status of the last 32 days
