General Introduction:
LRF-2000SG Pipe type ultrasonic flowmeter consists of the main unit and pipe transducer.
Pipe type ultrasonic flow meter has the advantages including low starting flow rate,high measurement accruacy,etc  


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
