  
TKTBR-E is an inferential, multi-stream, wet dial, straight reading type meter for cold water, 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: 
☆    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) 
☆    Water temp. : not more than 30℃
  
 Maximum permissible error: 
Between qt (included) and qs is ±2%; 
Between qmin and qt (excluded) is ±5%. 
NOTE: The technical data conform to ISO4064 standard, class B.
