H250 with M8 indicator

The compact 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.

Mechanical indicator (M8M)
Without auxiliary power, the flow-dependent position of the float in the measuring cone is transmitted by a magnetic coupling to the scale in the indicator housing. Both adjustable limit values of the transmitters are also displayed on the scale.


Electronic indicator (M8E)
The electronic version with bar graph indicator features state-of-the-art sensors which record the position of the float without contact or hysteresis. By default, the system works with linear analog output in 2-wire technology (applied current 4 to 20 mA). The device can be operated with commercially available power supply units.
