Dry Type Multi Jet Mechanical Brass Water Meter Class B
External adjustment dry type water meter (LXSG-15-50) is composed mainly of the body, cover, counting mechanism, measuring mechanism, and other components, the counting mechanism and the impeller are completely isolated by the magnetic drive , and the word wheel reading part is dry and separated from the use of water for a long time to maintain a clear part of the reading, with antifreeze, anti-fog, Anti-fouling, and other features .
Application:
Measuring the qtotal volume of cold (hot ) water passing through the pipeline.Main features:
1) Simple structure.2) Easy to manufacture and maintain, low cost.
3) Durable, low water quality requirements.
4) Error is easy to adjust.
5) Flow ratio is relatively large.
6) Sensitivity is better.
7) Straight pipe requirements are lower.
Working Conditions:
Temperature classes: T30 T50 T90Water pressure classes: MAP16 MAP10
Pressure-loss classes: △p63
Accuracy:
From minimum flow rate (Q1) inclusive to transitional flow rate (Q2) exclusive:±5%From transitional flow rate (Q2) to overload flow rate (Q4): ±2% (Hot water meter:±3%)
