Description
- It is dismountable and its movement can be pulled out easily for repair and exchange without taking the meter from pipe. (The recorder can be replaced on condition that water is available)
- The recorder is sealed up so that readings are over clear.
- Measuring devices are general – purpose and can reduce alternate parts.
- Its parts are connected magnetically and work numbly and reliably because of slight obstruction.
- The pressure loss is small.
- It is durable.
- Cold
Water Temperature: 50°C
Water Pressure: 1MPa
∆P < 0.03 MPa
- From minimum flow-rate (Qmin) inclusive, to transitional flow-rate (Qt),exclusive: ±5%
- From transitional flow-rate (Qt) inclusive, to overload flow-rate (Qs), exclusive: ±2%
- Cold: Exclusive: ±2%
Dismountable spiral cold water is for recording discharge, flowing through its pipe. It can not record the amount of polluted water end corrosive liquid.
