i want to design a non invasive ultrasonic flow meters using arduino uno and these transducers https://www.unictron.com/ultrasonic-transducers/products-overview/ultrasonic-liquid-transducer/mpya/

now i want to design the driver circuit for this bu i am unable to find any relevant info regarding that

 

Have you looked at the datasheets or application notes to see what they have to offer?

You'd need to provide a lot more information about your application and requirements to get much assistance.

 

i have seen the working of hc sr04 it has a max232 ic at its receiver end and some resistors and capacitors for filtering out noise and it has an op amp at its receiving end to amplify the receiving signal with some resistors and capacitors , i got the working of it but i dont know which ic to use and what should be the resistor capacitor values , above all of it i want both of my transducers to work as receiver and transmitter, can you please help me in it i have attached the schematic of hc sr04 sensor can you explain me exactly what each and every single resistor and capacitor is doing, why they have that specific values and whats the logic behind it

 

For an ACCURATE ultrasonic flowmeter there is a bit more complexity, and probably a higher performance op-amp than the LM324.
Is the circuit shown that actual product, or is it a design intended to duplicate the original product? AND, how will the ultrasonic transducers in the link couple to the fluid in the pipe???

 

The circuitory was of the hc sr04 sensor which has a frequency of 40 khz and i am having are of 1 mhz the circuitory will change i want to know what should go in the circuitory to run this

 

One megahertz is a rather higher frequency for keeping track of phase shifts and such details. And the LM324 is not a good choice for such high frequency operation. What is the intended benefit of operating at the much higher frequency?? Do you adequately understand the functions of the code running in that OTP processor??

 

hi MisterBill2

i am trying to make an ultrasonic flow meter using that, which ic can i use instead of lm324 and the uC is used to generate the pulses there i will be using some other controller for that purpose

 

Good Luck!!

 

can you help me in that, i am completely clueless to where to even start

 

Both the TI (Texas Instruments) and the Analog Devices websites include excellent tutorials about selection of op-amps for applications. My method has been to look in the product data books to see which devices are recommended for a specific application, such as high frequency or low noise. Those sources are more trust-worthy than others.
