NMF Membrane Level Monitor
Brand: KOBOLD Instruments, IncMembrane level monitors allow economic level monitoring of bulk goods in storage vessels.
They may be used to indicate full and empty states and load demand for dusty, powdery, granulated and grainy bulk goods. They are suitable for use with bulk materials (0.3 to 2.5 t/m3) and particle sizes up to 30 mm.
The devices will operate faultlessly provided the bulk goods flow easily at not too small an angle.
Only such materials exert sufficient operating pressure on the detector fitted in the wall of the silo.
