Dry Dial Removable Mechanism (Cold Water)

Features

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.

Working Conditions

Cold
Water Temperature: 50°C
Water Pressure: 1MPa
∆P < 0.03 MPa

Accuracy

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%

Application

Dismountable spiral cold water is for recording discharge, flowing through its pipe. It can not record the amount of polluted water end corrosive liquid.
