How to Deal with The Measurement Error of Ultrasonic Flowmeter?

Ultrasonic flowmeter is a very convenient flow meter, compared with the traditional flowmeter, ultrasonic flowmeter with its simple structure, small pressure loss, strong applicability, easy installation and maintenance and other unique characteristics, in the semiconductor, petrochemical, thermal power, water treatment industry has been widely used.

In actual use, many users have doubts about the ultrasonic flowmeter due to the poor grasp of the main points of use of the ultrasonic flowmeter and the unsatisfactory measurement effect. Among them, the user has encountered more problems in the use of "large measurement error". Today I'm going to tell you how to deal with this situation.

（一）

Cause: The distance of the straight pipe section does not meet the requirements of the first 10D and the last 5D (10 times the pipe diameter, 5 times the pipe diameter).

图片2

Processing: Find other sensor mounting locations.

（二）

Reason: The parameter setting of the main pipe is inconsistent with the actual pipe parameters (when there is a 1% difference in the inner diameter, the measurement error will be about 3%).

图片3

Processing: Correct input bore value.

（三）

Reason: the distribution pipe is in a state of water insufficiency or sediment accumulation (the part of the cross-sectional area is reduced to increase the measurement error).

Prossecing: Transfer to vertical pipe section or other location.

（四）

Reason: Long pipeline life internal precipitation scale

（五）

Processing: The scale thickness is entered as the liner value.

Reason: The size of the sensor is incorrect.

Processing: Reinstall the sensors and ensure that the distance between the sensors is correct.
