Weld a tube with an internal diameter of 28...30 mm / 1.1...1.2" to the bottom of the tank.
i
Make sure the tube aligns with the process connection at the top of the tank.
•
Lower the probe into the tank.
WARNING!
If the instrument has to measure the level of dangerous products (ammonia etc.), make sure
that the instrument has the METAGLAS
