Flow sensor IMF

The IMF is a flow sensor for fl ows of 3.5m3/hr to 10m3/hr with a horizontal mounting.

Its particular construction ensures high measuring accuracy and reliable measurement stability. Its connection and structural dimensions are in line with DIN ISO 4064. If desired we can supply a flange version with flange dimensions in line with DIN EN 1092.
