 Intrinsically-safe circuit. National explosion-proof product manufacture license granted  
(License No: XK06-123-00596. For details, refer to the All China Industrial Product  
Manufacture License Information Network). Specifically designed for explosion-prone  
environment.  
Use of low-tension, multi-pulse and DSP techniques for higher accuracy and resolution,  
and error correction and anti-interference capabilities (Certificate of China Laboratory  
Authentication Commission granted).  
In micro-power consumption design. Battery power or 2-wire power supply system  
selectable. Capable of working continuously for a period of over 6 years with a single  
battery cell (Service life of the stand-by battery: > 6 years).  
Use of ultrasonic flowrate transducer for higher measuring reliability and accuracy (Patent  
No.: ZL01221678.X). No mechanical moving parts. Invulnerable and maintenance-free.  
  The pipe section-mounted SCL-71xiw version is provided with a special transducer which is in unique structure and can be cleaned on-line with
 water flow under pressure (Patent No.: ZL200520007604.5). For its maintenance, there is no need to shut down the water flow (shutdown of water
  flow is required in the case when a conventional flowmeter is used).
  The SCL-71xi is a dual-transducer version – the first of its kind developed in China (Patent No.: 200420006380.1). For its mounting and maintenance,
  no shutdown of water flow is required.
  The SCL-71xiz flowmeter is a cast-iron pipe section-mounted version – a patented product for its unique configuration and structure (Patent No.:
  200620018697.6).
