The advantages of handheld ultrasonic flowmeter are:
1, non-contact measurement, small size, light weight, easy to carry.
2, the installation of the sensor is simple and easy, used to measure various sizes of pipe sound guide media.
3, the measurement process does not need to destroy the pipeline, do not need to stop production, the sensor is not in contact with the measured medium, no pressure loss.
In the purchase should pay attention to:
1, precision functional inspection
Precision level and function According to the measurement requirements and use of the instrument precision level, to achieve economic. For example, for trade settlement, product handover and energy measurement, the accuracy level should be higher, such as 1.0, 0.5, or higher; For process control, select different precision levels according to control requirements; Some just detect the process flow, do not need to do precise control and measurement occasions, you can choose a slightly lower accuracy level.
2, measurable media
When measuring the medium flow rate, instrument range and diameter, the full degree flow rate of the ultrasonic flowmeter can be selected in the range of measuring the medium flow rate of 0.5-12m /s, and the range is relatively wide. The selection of instrument specifications (caliber) is not necessarily the same as the process pipeline, should be determined according to whether the measured flow range, in the flow rate range, that is, when the pipeline flow rate is low, can not meet the requirements of the flow meter or the measurement accuracy cannot be guaranteed at this flow rate, it is necessary to reduce the diameter of the instrument, so as to improve the flow rate in the tube, and obtain satisfactory measurement results.
