Water Meter Westechaus 4 Inch merupakan alat ukur yang digunakan untuk mengukur laju air serta volume air pada perpipaan.
Characteristic :
- Dry type magnetic drive
- Vacuum sealed counter, frost proven, keeping clear reading for long term
- Removable structure, easy installation and maintenance
- mechanic system for normal use
- Bog flow capable, low head loss
- Remote transmission device can be added upon request
- All technical date accord with GB/T778.1-3-2007
Working condition :
Water temperature 0°C ≤1 ≤30°C (for cold water meter)
0°C ≤1 ≤90°C (for hot water meter)
Water Pressure : ≤1 MPa
Maximum Permissible Error :
From the minimum flow rate Q1 (Including Q1)
to the lower of the transitional Q2 (Excluding Q2) ±5%;
to the higher zone of the maximum flow rate (including Q4) : ±2%
