FIELD: aids for gas dosing. ^ SUBSTANCE: gas dozer can be used for dosing small amounts of gas. Gas dozer has two cavities which communicate with each other, gas inlet and outlet branch pipes, partition mounted for vertical movement mounted between two cavities. Partition is made of ferrous liquid. Partition is made between gas inlet and outlet branches. Partition is hold by field of ring-shaped magnet through air gap. Free surfaces of partition have shapes of menisci which shape is defined by non-uniformity of magnetic field at radial direction. Inductance coil is placed inside ring-shaped magnet. Precision and reliability of dosing is sustained permanent at different pressure of their sources. ^ EFFECT: improved precision; higher reliability. ^ 1 dwg |
