H250 M8
Variable area flowmeter for liquids and gases
- Mechanical or with electronic bargraph indicator (4…20 mA/HART®)
- Flange: DN15…25 / ½…1"; also NPT, G, hygienic connections, etc.
- -40…+200°C / +392°F; max. 145 barg / 2102 psig
Overview
The H250 M8 is a variable area (VA) flowmeter with electrical signal output and bargraph indication or mechanical indication with two optional limit switches. The compact flowmeter allows space-saving installation. It is thus highly suitable for installation in limited spaces.
The H250 M8E version features magnetic sensors recording the position of the float without contact or hysteresis. Standard system operation is with a linear analogue output in 2-wire technology (4…20 mA). The H250 M8M version operates without auxiliary power. The flow value as well as the optional two limit switch setpoints are displayed on the scale. It has approvals for use in hazardous areas and comes with a wide range of process connections.
