Liquid container with level measurement arrangement for water heater - has measurement tube with float whose position is detected electromagnetically or by light barrier

摘要

The liquid container has a measurement tube connected to the contents and a float supported by the liquid column inside the tube. At least one measurement sensor detects the protrusion of the float through a level marker. The sensor can detect the float position electromagnetically or using a light barrier. The level signal is used to control an electromagnetic liquid inlet valve. ADVANTAGE - Liquid container and level measurement arrangement enable use of electro-optical level display and automatic level control.
