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.

Highlights M9 indicator

	Simple, low-cost installation: Measure and display without auxiliary power supply
	Large scale for good readability
	Modular and flexible to adapt to customer-specific applications - 2 limit switches (NAMUR or 3-wire transistor) - 2-wire analog output 4…20mA with HART - Profibus PA interface - 6-digit flow counter with pulse output (non Ex)
	Optional stainless steel housing for corrosive atmospheres
	SIL 2 certified
	International approvals for use in hazardous areas (ATEX, FM, CSA, NEPSI) and nuclear power plants (N/NPT stamp)

Highlights H250 measuring cone

	Sturdy stainless steel construction for high operating pressure up to 3000 bar and extreme process temperatures from -200°C to +300°C
	Optionally available with PTFE/ceramic liner for acids and alkalis
	High application security, even with extremely small flows
	Excellent long-term stability
	Upper limit of measurement for liquids: 10 to 120,000 l/h (water: 20°C)
	Upper limit of measurement for gases: 0.7 to 2800 m3/h (air: 20°C, 1.013 bar)
	Accuracy 1.6 % of measured value acc. VDI/VDE 3513-2 (qG=50%)
	Many different process connections - Flanges as per EN (DN15-DN100), ASME and JIS - Screw and clamp connections
	Special design for the food and pharmaceutical industry with EHEDG approval

Further options

	Magnetic filters, if the medium contains particles which can be magnetically influenced
	Float damping for pulsating flows or low operating pressure (especially when measuring gases)
	Display damping ensures measured value is easy to read

The H250 is also available with stainless steel housing and is thus perfectly suited to sterile environments.
The new 2-wire electronics makes it one of the most cost-effective measuring instruments on the market for liquids and gases.
The H250 is the only all-metal variable area measuring instrument with EHEDG certification.
