The standard solution for the process industry. H250 flowmeters 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.
