HANLA AIR PURGE REMOTE LEVEL SOUNDING SYSTEM CT-180


The operating principle is based upon the measurement of the hydrostatic pressure by providing a constant low flow of air or neutral gas into a probe which opens at the tank bottom. The flow regulator ensuring a constant pre-set flow at the end of the sounding pipe in the tank irrespective of the supply pressure. Gauge saver is used for protecting the level indicator against over
pressure. The blowing valve is used for sending the full air pressure through the signal line for cleaning purposes. The air supply valve is used for isolation from other channel without any influence.
