Detailed Product Description

The technical characteristics of the product:
  1. The base meter uses the high quality dry spring signal water meter.
  2. The valve is carefully designed, and the structure is reasonable.  It avoids the phenomenon of water-hammer and vibration.  The work is stable.  The valve used the inside and outside spurt models, is completely made from the anti-corrosive material (patent number ZL01278800.7).
  3. The valve engine uses independently designed low power loss anti-disturbance electrical machinery, and the monolithic machine may automatically recognize the valve condition.It repeatedly starts the engine, guarantees the accurate control of the open and closure position of the valve (patent number ZL01275828.0) 
  4. The controllers and the water meter are designed to be completely sealed, be able to operate under water.
  5. The controlling circuit uses the advanced high quality multi-function , low power loss chip. Human nature design, simple operation,complete functions. 
  6. Uses the battery to provide the electricity and the battery is guarantied to use for more than 4 years. 
  7. Data exchange uses separate card and control structure:
       a) Way 1: through the plug-in unit, the socket hangs at the place easy for the operation;
       b) Way 2: using the double monolithic integrated circuit technology, uses the hand-held machine to do the data acquisition and control, has solved waterproof problem of the socket when installing under the well.
The main parameters for the base meter:
  1) The sampling of double spring tube is: for every1m3 (or its ten times, hundred times), it will send a pulse. 
  2). From (including) the lowest current to the low capacity area which does not include the dividing current <= ±5%
  3). From (including) the lowest current to the low capacity area which include the dividing current <=±2% 
  4). From (including) the dividing line current capacity to the high area which includes the maximum current capacity <= ±2% 
  5). The working pressure: <= 1.0MPa 
  6). The water temperature: 0~ 50
