I just need the (Auto count) preset measurements that make a beep at recurring intervals. I don't need it to do anything else. Just need the beep at preset measurements.
Not sure exactly what you want but if it just one of those wheel counters then all you need is your own counter to beep every so many turns or part turns and that can be done with simple hardware no programming required.
This simple AU$32 wheel counter could easily have a circuit added to perform that task.

Could u please show mower how to do this

Who is mower?
Do you already have a trundle wheel? If so can you attach an image and documentation to see if it can be modified to trigger the solenoid at set intervals?

Thank for your input
Could anyone tell me company that will write codes for a project

No I know of no company that can build a special purpose trundle wheel and control system. It would cost you a lot of money.
These forums are about helping each other interested in building their own electronic projects.
It is also hard work trying to figure out exactly what you have already and other details needed for a sensible response.
What is the role of the relay on your sound operated circuit? I am guessing it is turned on/off by a sound picked up by the microphone? Maybe a clap on/off light switch. Or in this case to turn a solenoid on/off?
Do you actually have a trundle wheel and your only problem is it doesn't have a pre-set "distance covered" buzzer to operate the sound operated circuit?
Does the relay operate a spray can? Do you have pictures of that?
You could make your own trundle wheel something like shown below (but replacing the sound operated circuit with a direct connection to a solenoid circuit). But as for making a solenoid operated spray can? I remember they used to have automatic fresh air spray cans that would operate at fixed intervals of time so I assume they could be hacked for parts.

Your plan, as illustrated, does not make any sense and cannot be implemented as shown. There are too many loose ends.
How does the turning wheel make a beep ?
What is the purpose of the digital display ?
What are the connections and specifications of the solenoid (or relay controlling it) ?
How does the wheel know when to beep ?
How do you prevent ambient noise from interfering with the circuit board's beep listener ?
If you can produce a beep, why not use that directly to trigger the relay instead of triggering a mike to trigger a relay to drive a solenoid ?
Anything seems possible when you don't know what you're talking about.

The wheel is a digiroller plus 11. Has auto count and it a distance roller. You can set any measurements and it will make a beep everytime that measurement comes around
Example set 9' beep 18'beep 27'beep
Example set 3' 2" beep 6' 4" beep and so one
Pls tell me more about your last sentence u wrote sound easier
Thank u so for ur help

If you have a device that beeps at your desired intervals, then you should be able to take off the cover and identify the buzzer or beeper which produces that sound.
You might then be able to take that signal, amplify it with a transistor and pass the amplified signal off to your solenoid.

@will would you please tell me what exact components i need.
And draw me a schematic
And tips would be helpful
Thank u

Google "transistor amplifier" for examples and some descriptions of setup and calculations.
You'll be taking whatever voltage is applied across the "beep" component and amplifying it to whatever voltage is required to drive your relay or solenoid.

@will would u please tell me the components I need and a diagram pls so I can put it together
- P.s do I have to have a relay or can the transistor amplifier fire the seloniod

The information you need is available from Googling transistor amplifier calculations, from whatever part of our device beeps and the information on your relay or solenoid (your last drawing mentions both).
You need to do some of the work yourself or you'll never learn. This forum is intended to help people not provide a custom solution as you seem to want.

@will can I get the transmitter amplifier to run the seloniod with out a battery or relay
