It is an industrial water$-$filling machine control system to make it automatic with $8$ nozzles to fill at the same time. If I am missing anything let me know too. Tube are $5/8$ in$.$

Can I get affordable options for the following and exact models, not that hard to obtain:

Sensors:

Photoelectric Presence Sensors $(8$x$)$: Detecting bottles reliably with different materials and colors.

Ultrasonic Level Sensors $(8$x$)$: Contactless, hygienic level detection for accurate filling, unaffected by foam or bubbles.

Pressure Sensor $(1$x$)$: Monitoring water pressure for consistency and triggering low$-$pressure alarms.

Actuators:

Pneumatic Pistons $(8$x$)$: Securing bottles firmly yet gently during filling.

Solenoid Valves $(8$x$)$: Precise and rapid control of water flow.

Electric Motors $(2$x$)$: Powering conveyor belt and nozzle movement.
