- Product Introduction
Overview
Chint rotor-type wet cold water meter is a measuring instrument, which is used to measure the amount of water flowing through the water pipe. It is suitable for small industrial water and household water. Large counting range, high accuracy and other performance requirements, meet the GB / T778.1 ~ 3 ~ 2007, JJG162-2009 test procedures.
Working conditions
Water temperature:0.1℃ ~ 30℃
Water pressure: △p≤1.0MPa (10bar)
Product Features
Vacuum treatment is used on counterpart. Isolation of outdoor air and water keeps the counter always clear and without atomization phenomenon.
The header part is waterproof with anti-magnetic function.
