Profile: Krohne Ltd produces process measurement instruments. Our products include variable area flow meters, ultrasonic flow meters, mass flow meters, vortex flow meters and level measurement products. The H250 flow meters based on the float principle are versatile and can be used for conductive and non-conducting liquids and gases. The sturdy all-metal design ensures high resistance to pressure, temperature and media and stands up to extreme application and environmental conditions. The position of the float is magnetically transmitted to an analog indicator to display the measurement without auxiliary power. The hygienic conductive sensors type LS 7000 series are used for level detection or dry run protection on conductive liquids. These sensors pick up the electrical resistance of the tank product when the electrode is in contact with the product. The wall of the vessel or the pipe acts as reverse potential.
