FIELD: oil and gas industry. ^ SUBSTANCE: unit contains a housing with opening cover. Inside the housing there are arranged control unit with electrical equipment, hanged tank for chemical agent provided with agent availability control system and dosing pump. The reservoir is provided with filling hole for chemical agent. In control unit there are dosing pump control circuits located. The reservoir is installed by means of assembly functioning both as fastener and as weight measuring system. On the upper part of the reservoir the assembly contains two distant from each other metallic slats rigidly fixed with the housing. Assembly is provided with two U-shaped levers consisting of beam and branches. Levers are installed under mentioned slats in inversed manner with beams towards each other. Each lever is connected by branches body to the first and the second slats by means of hinged joint. End parts of branches of U-shaped levers, closer to end ones, are connected to the reservoir by means of hinged joint. Levers beams are connected to each other by means of hinged joint of each beam with strain-measuring sensor which outlet is connected to control unit. ^ EFFECT: simplifying the design, improving operating reliability, reducing material costs. ^ 8 cl, 5 dwg |
