Hello, Have a great day. We are startup offering services in product development. We will ship you one working prototype. Please keep in mind that ultrasonic sensors are not very accurate, specially when ambient temp rises or decreases it results in erroneous readings. We can compensate it with level sensor. Please feel free to contact us. Best Regards, Shahbaz.
