Embodiment Construction

[0027] Refer to the attached Figure 1-4 , it is possible to see a first embodiment of a device 1 for monitoring the operation of a metering dispenser 2 of a liquid additive 3 in a main liquid stream flowing in a conduit 4 connected to the metering dispenser 2 . The drive source for the dose dispenser is formed by the main liquid flow actuating the dose dispenser, which operates without drive power. The above dosage dispensers are known, in particular from patents EP 0 255 791 B1, EP 0 885 357 B1 and WO 2012 / 046162.

[0028] The dose dispenser 2 comprises a suction conduit 5 adapted to be inserted into a volume of liquid additive contained in a container 6 . The pipe 5 is connected to a suction pipe section 5b ( Figure 4 ). The housing B of the device 1 comprises, opposite the duct 5 , a connection piece 7 suitable for being connected to the lower part of a cylindrical sleeve 8 of the dose dispenser 2 . Another section of the suction duct (not visible) is provided in the...

Abstract

The invention relates to a device (1) for monitoring the operation of a dose dispenser (2) comprising a suction duct (5) suitable for insertion into a housing In a liquid additive (3) in a container (6), said monitoring means comprise means (D) for detecting inhalation of the liquid additive and means (A) for displaying operating parameters of said dosing dispenser, so Said detection device (D) comprises a tube (10), said tube (10) being separated from said suction duct (5), one end (10b) of said tube (10) being arranged to be inserted into a container of liquid additive ( 6), and wherein the other end (10c) remains fixed relative to the suction duct so as to be located outside the container, the other end (10c) is closed and provided for use in the pipe (10) A sensor of air pressure, the sensor outputs an electrical signal, and means for using the signal from the sensor, the means being connected to an outlet of the sensor to provide operational information.

Description

technical field [0001] The invention relates to a device for monitoring the operation of a doser of a liquid additive in a main liquid actuating the doser according to the suction and delivery phases, the doser comprising a suction duct , the suction conduit is suitable for insertion into a liquid additive contained in a container, the monitoring device comprises means for detecting the inhalation of the liquid additive and means for displaying operating parameters of the dosing dispenser, these means being suitable for The data provided by the detection means is used to convey a message at least when the level of the liquid additive in the container reaches a lower limit and when an untimely rise in the liquid level occurs in the container. Background technique [0002] FR 2 798 705 proposes a monitoring device of this type comprising, as means for detecting the intake of a liquid additive, two pressure sensors placed at the ends of the pressure loss element , the pressure...
