Ultrasonic Level Meters
My company could produce handheld type ultrasonic flow meter and wall mount ultrasonic flow meter.
For wall mount ultrasonic flow meter, it could be installed together with clamp type sensor and insertion type sensor.
Insertion type sensor is used on large diameter pipe or cement pipe.
This type sensor has bettery accuracy and stability.
When install the sensor, there has special tools that could install the sensor directly and don't need to close the valve or cut off the liquid.
So it will be convenient for working site.
