H250 with M9 indicator

  • H250 with M9 indicator

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.

H250 with M9 indicator

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

. 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


H250 M9 stainless steel

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.

The H250 Food flowmeter is a further development of the tried and tested all-metal instrument and was especially designed for use in the food and pharmaceutical industry. It is used to measure liquids, gases and saturated steam. It features a hygienic surface with a surface finish of Ra < 0.8 μm as well as a design free of dead spaces.


The only EHEDG-certified variable area flowmeter approved for the food and pharmaceutical industry features smooth stainless steel surfaces with a surface roughness of the parts in contact with the medium of < 0.8 μm, which makes it difficult for deposits to stick and easy to clean.

Combined with a design devoid of dead spaces and stagnation zones, microorganisms cannot stick and multiply.

Technical Features

. All-metal flowmeter featuring design devoid of dead spaces

. Surface roughness Ra < 0.8 μm

. CIP and SIP compatible (200°C)

. FDA conforming materials

. Tri-clamp connections, DIN 11851, flange, etc.

. Indicator in modular design

. Optional heating jacket

. Optional stainless steel housing

. EHEDG approval

Areas Of Use

. Milk, cream

. Cooking oil

. Carbon dioxide in the beverage industry

. Insulin

. Ultrapure water

. Air measurement in cleanrooms

The measuring instruments can be cleaned (CIP) and sterilized (SIP) while intact. There are suitable connections and FDA conforming materials for the food and pharmaceutical industry.
