Supply cmgl211 intelligent boiler drum level gauge

  The importance of cmgl211 intelligent boiler drum level gauge is well known
However, for a long time, the balance vessel (differential pressure) measurement method used in the continuous boiler drum level measurement technology has many defects that cannot be improved, mainly reflected in the following aspects:
1
The measurement under all working conditions cannot be carried out, and “ False water level ” It takes a long time to measure, establish stable differential pressure conditions under unstable operating conditions such as boiler startup, shutdown, evacuation, continuous discharge and accident, or it takes a long time to recover, or it is simply unable to establish normal differential pressure, which requires manual intervention

2 、 Under stable operating conditions, due to structural constraints, the compensation problem of system measurement error caused by water side absolute temperature cannot be completely solved
Under accident conditions such as boiler water shortage and full supply, excessive system measurement error may lead to serious consequences

3
The structure is complex, there are many static sealing points, the construction scale is large, and there are thermal insulation problems in winter

4
The measurement time delay is long, which can not immediately reflect the boiler water level change, and the measurement signal regulation quality is poor

5
Due to the heat release from the condensing cylinder, the use cost is very high
