 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.
