Level measurement in the condensate-feedwater-tankInquire now
In a condensate return tank of a steam supply water levels have to be maintained within a certain Min / Max range.
Usually conductive rod probes are used for this measurement task.
Because of the low conductivity of the condensate, this measurement method always create difficulties.
A hydrostatic measurement is also not recommended, as there is always a slight overpressure in the boiler.
Quick and easy installation
Temperature stability up to 200 ° C
Pressure resistant -1 .... +100 bar
Continuous measurement without dead zone, (thus the tank can be completely filled)
Also suitable for hygienic applications
For critical applications is a mass pipe available
|The process data|
Contents: condensed water
Container: horizontal cylindrical tank
Temperature: 90 ° C
Process connection: flange or thread
An interesting alternative is the capacitive rod probe FMI 51. The DK-value of teh condensate is over 50 and therefore makes no problems.
The probe may e.g. be mounted on an existing flange, any existing neck tube can be cleared using an inactive length. Even in an existing bypass tube the probe could be installed - it only needs be fully washed with water.
The output 4-20 mA signal can be easily evaluated using the process indicator DPA in order to realize the feeding.
