      DS78TBR-15~20E/S (plastic body)
       

      DS78TBR-E/S is an inferential, multi-stream, wet dial, straight reading type meter for cold water, and it¡¯s Suitable for domestic use. Body and 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:
      * Internal filter of adequate filtering section.
      * Large measuring range and high flow accuracy
      * Low start-up flow, high sensitivity, long life of service time.
       
      WORKING CONDITION:
      * The max. admissible pressure: 1.6MPa(16bar)
      * Resisting water temperature of  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 B.
