BATCHER OF REAGENT IN WELL Russian patent published in 2009 - IPC G01F13/00 

FIELD: physics, measurement.

SUBSTANCE: invention is related to the field of measuring equipment and may be used in batching of reagent solutions in well in ascending flow of fluid. Technical result is provided by the fact that batcher comprises container body containing cell for reagent inside and having lateral lower inlet and upper outlet openings. At that lower outlet opening is closed by means of gate valve, which originally serves for prevention of liquid and gases ingress in cell. Gate valve operates when actuated by cables, which on top pass through distributing orifice that serves both as connecting part for fastening of batcher container body to pump compressor pipe. Upper outlet opening is equipped with check valve. Cylindrical cell for reagent is pressed to internal wall of container body by thrust collar and has cover and bottom with openings, and lower part of container body is equipped with bottom in the form of cover.

EFFECT: improvement of reliability and provision of possibility to batch reagents with not only hard but also liquid and amorphous condition, and also possibility to control dose of reagent and combination of reagents.
