   Catalog > ENERGY MEASURING  > 130 Energy Meter    


  NAME: 130 Energy Meter

 MODEL: Model 130

  SIZE:

130 series products are combined heat meter. The radial impeller flow sensor, which with power supplied by inside lithium battery, is adopted in series products, which not only fit to apply in networking but also fit to apply in independence environment. The distance between the calculator and flow meter should be not more
than 10m. The delivery standard length is 1.5m .The wire of temperature sensor is maximum length with 25m and the delivery standard length is 1.5m.The series products with better capability of against magnetism disturbing.
