Q1: Can an ultrasonic flow meter have perfect accuracy?
A1: In an ideal world, the flow readings from your process meter would be exactly correct, without any type of deviation. Unfortunately, this is not the case, and the errors inherent in measurement must always be identified, accounted for, and minimized as much as possible.
Q2: Does an ultrasonic flow meter need to be calibrated?
A2: During the production of a flowmeter, several steps are required such as coil winding, lining processing, and electrode assembly. This series of operations can cause a certain amount of error and dispersion in the device, so a calibration process is required to correct the accuracy.
Q3: Do ultrasonic flow meters have temperature compensation?
A3: Yes. As long as these temperature variations are within the temperature compensation range, the output reading compensates for the temperature variations.
Tips: Can I clean the sensor in my ultrasonic flow meter?
No, you cannot. The sensor element cannot be accessed without special factory tools. It is also fragile and will be damaged if you try to clean it from the outside. Do not attempt to clean the sensor in the ultrasonic flowmeter through the liquid.
