SU18405A1 - A device for measuring the amount of fluid flowing - Google Patents

Description

The proposed instrument is one of those instruments for measuring the amount of flowing fluid, in EOIH used spools controlled by an electromagnet, with the inclusion of electric meters. The device works by successively passing the fluid through two chambers — reception and measurement, with the help of a float device and a gold, raising the electromagnet and lowering with the rupture of the depy from its own gravity. The author believes that such a device can reliably take into account the amount of fluid flowing at the lowest cost and pressure of it.

The drawing shows the device in vertical section.

Liquid is poured into the receiving chamber 4 through the inlet pipe i through the upper openings 8 in the spool 5 and in the walls of the device. When the cavity of the lower measuring chamber 5 is emptied, the electric current from the source 12 follows this way: through the additional electromagnet, 9, contact 15 of the lower float 7, fixed contacts Jб, through the contact -4 of the upper float 6, through the electromagnet iO and through the electric meter 11. Coil 10 pulls up the spool 5, which in the raised position closes the flow and outflow of fluid, respectively, through pipes JZ and 5, informing that

at the same time, through the holes 1B and the recess 17, the upper receiving chamber 4 of the laboratory with the lower measuring chamber 5; as a result, the last chamber o is filled with liquid overflowing into it from chamber 4. Until the bottom chamber is completely filled, the spool remains elevated all the time, and only VSP.1 OUTFLOW 6, interrupting contacts S and 16, will interrupt the current: then spool 5 will lower, and the float 7, coming off the electromagnet 9, floats up. At the same time, the flow of fluid through the pipeline 1 at the top and its discharge from the exhaust pipe 5 to the vizu will be resumed: the operation cycle is repeated, each time the mark in the 11 and 1 electromagnetic meter is counted in the number of strokes connected to the spool. An ordinary plunger S is used to control the amount of fluid flowing through it; screwing or unscrewing it, respectively, changes the strength of the measuring chamber o.
