Ultrasonic NV Measurement System
Ultrasonic NV measurement system enables automated E-Coat paint feeding
The ultrasonic NV measurment system measures the Non-Volatile (NV) elements of the E-Coat paint. It is configured to feed the E-Coat paint when the NV measurment value reaches the low limit. This allows lowering of the maintenance cost and a stable paint feeding process.
How it works
Inside an E-Coat paint piping, an ultrasonic signal is sent out from one side of the piping, and receives the signal on the opposing side. The signal attenuation rate measures the concentration level of the obstruction material (NV).
The greater the concentration of NV in the paint, the greater the attenuation (weaker signal). This method allows for stable NV% measurment (accuracy around ±1%)。
