      DS78TBR-15~50E/C (Class C)
       

      DS78TBR-E/C is an inferential, multi-stream, wet dial, straight reading type meter for cold water, and it¡¯s suitable for domestic use. Brass body, internal mechanisms are made from wear-resistant, waterproof, antimagnetic and antiscaling plastic material. No leak, mechanical transmission not effected by external magnetic fields or ferrous particles in water.
       
      SPECIALITY:
      ¡î    Internal filter of adequate filtering section.
      ¡î    Large measuring range and high flow accuracy
      ¡î    Low start-up flow, high sensitivity, long life of service time.
       
      WORKING CONDITION:
      ¡î    The Max. Admissible Pressure: 1.6MPa(16bar)
      ¡î    Water Temp. : not more than 50¡æ

      Maximum permissible error:
      Between qt (included) and qs is ¡À2%;
      Between qmin and qt (excluded) is ¡À5%.
      NOTE: The technical data conform to ISO4064 standard, class C.
