H250 with M10 indicator

The ideal solution for the process industry

The 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 determined without contact or hysteresis, using magnetic field sensors and is displayed on the digital indicator.

Highlights M10 indicator

	Integrated functionality - Graphic display for measured value and counter display - 2 limit switches (NAMUR or 3-wire transistor) - 2-wire analog output 4…20mA with HART - 12-digit flow counter with pulse output and reset input
	Pressure resistant, enclosed housing
	Operated using keys or magnetic stylus
	International approvals for use in hazardous areas (ATEX, FM, CSA, NEPSI) and nuclear power plants (N/NPT stamp)
