A tint measuring device configured for being connected in series in a fluid flow circuit, the tint measuring device including at least one light source configured for emitting polychromatic light towards the fluid in a measurement zone; a light sensor configured for receiving a light signal either reflected from or transmitted through the fluid, the reflected or the transmitted light signal corresponding to the optical reflection or the optical transmission, respectively, by the fluid, of the polychromatic light emitted towards the fluid by the at least one light source; and a computing unit configured for performing a spectral analysis of the light signal received by the light sensor and for determining a chromatic signature of the fluid.

A modular block for an electric pump for a fluid product, including a main body defining a housing extending along a main axis, the main body having a general shape having a discrete rotational symmetry relative to a reversion axis, the main axis of the housing within the housing extending on a first side of a central plane outside the central plane, the reversion axis being included in the central plane, and a pumping device extending at least partially in the housing of the main body.

A device for monitoring a pneumatically-actuated alternating linear displacement pump is provided, and a system for monitoring a pneumatically-actuated alternating linear displacement pump is provided, which include elements for sensing pneumatic pressure, elements for transmitting a signal representative of the sensed pneumatic pressure, and elements for managing the pneumatically-actuated alternating linear displacement pump in accordance with the transmitted signal representative of the sensed pneumatic pressure.

A piston carrier supports an elongated, slender piston rod for reciprocation in a pump cylinder to pump fluid into and out of the cylinder. The piston rod is made of a material such as sapphire or zircon and has a diameter less than about ten millimeters, and the pump can provide flows of from about 50 nanoliters to about 250 microliters per minute at pressures of several hundred bars. A drive motor rotates a threaded screw and a drive nut of a drive system applies a linear drive force to the piston carrier. A ball and socket connection between the drive system and the piston carrier avoids the need for precise alignment to prevent breakage of the fragile piston. A magnet in the socket holds the ball in place and avoids the need for a spring or other mechanical holder. The socket also includes a ring of a low reluctance material surrounding the ball to increase the magnetic retention force.
