What are the advantages of handheld ultrasonic flow meters?

1. Installation and maintenance, ultrasonic flow meters are the most convenient and do not require process shutdown, while the other two types of land slow-release meters need to be parked before installation

2. Measurement medium, mechanical water meters generally only measure tap water, electromagnetic flow meters must measure conductive media, and ultrasonic flow meters have the widest measurement range

3. In terms of accuracy, electromagnetic flow meters have the highest, usually up to 0.5 levels, followed by ultrasonic flow meters, usually at 1 level, while mechanical water meters have the worst accuracy

4. Stable and early cherry blossom modulus, generally electromagnetic flow meters are the best, followed by water meters, while ultrasonic flow meters have the worst accuracy

p>5 Compared with electromagnetic flow meters, electromagnetic flow meters generally have advantages for small pipe diameters, while ultrasonic flow meters have advantages for large pipe diameters. Mechanical water meters are the cheapest in terms of price. Additionally, mechanical and electromagnetic meters must come into contact with liquids and are contact meters. Therefore, anti-corrosion, leak prevention, and wear issues often need to be considered; The price boundary between ultrasound and electromagnetic is obvious below DN600MM, and ultrasound is expensive The price of ultrasound above DN600 remains unchanged, while the price of electromagnetic waves increases logarithmically. 2. Installation method of handheld ultrasonic flowmeter sensor. The most commonly used installation methods for handheld ultrasonic flowmeter sensors are Z meth Handheld flowmeter

od, V method, and N method, and the selection method needs to be determined according to the diameter of the pipeline and the state of the inner wall. When the inner wall of the pipeline is severely scaled or the diameter exceeds 300mm, Z-method installation is an ideal choice. Installation requires fixing two sensors face to face on both sides of the pipeline, keeping the sensor center point line completely parallel to the pipeline axis, and ensuring that the ultrasonic signal penetrates the fluid in a straight line. This method has low signal transmission loss and is particularly suitable for stable measurement of high sediment pipelines. The V-method installation is suitable for pipelines with diameters ranging from 50-300mm and relatively clean inner walls. The sensor needs to be placed on the same side of the pipeline surface, forming a V-shaped signal path with an angle of about 45 degrees. This method simplifies the installation difficulty and can balance measurement accuracy and operational convenience in the medium pipe diameter range. It should be noted that the sensor spacing should be 1/5-1/6 of the circumference of the pipeline, which can be automatically calculated and confirmed by the instrument.

3. N method installation is a special scheme for small pipe diameters below 50mm. The sensor is also installed on one side of the pipeline, but the ultrasonic signal reflects multiple times through the fluid in an N-shaped trajectory, thereby increasing the effective propagation distance. This method can solve the measurement error problem caused by the short acoustic path in small diameter fluids. After installation, it is necessary to select the "N mode" calibration parameters on the debugging interface. B
