FIELD: measurement technology. SUBSTANCE: instead of one float, use is made of many small particles of various sizes made from polydispersional magnetic material, ferrite, for example. Indication of flowmeter is read-off visually by upper limit of suspended layer and is determined by means of oscillating circuit whose inductance is measured depending on filling with ferromagnetic material. Inductance coil is external along flow at linear increase of distance between turns. EFFECT: enhanced efficiency of measurement. |
