技术参数及原理江苏金湖东祥仪表以工作经验特别推出HR-SC手持式超声波流量计技术参数以及工作原理，HR-SC手持式超声波流量计采用外夹式传感测量液体流量。 Technical parameters and principle of HR-SC handheld ultrasonic flowmeter Jiangsu Jinhu Dongxiang Instrument specially introduced the technical parameters and working principle of HR-SC handheld ultrasonic flowmeter based on working experience. Sense to measure liquid flow. The installation process is extremely simple, and the Chinese-machine interface is easier to operate. Particularly suitable for flow balance testing and flow monitoring: drinking water, river water, sea water, cooling water, hot water, industrial sewage, lubricants, diesel, fuel oil, chemical liquids, etc.
Features ● Non-contact measurement method, small size, light weight, easy to carry.
● The installation of the sensor is simple and easy, and it is used to measure the sound conducting media of various sizes of pipes.
● The measurement process does not need to damage the pipeline, does not need to stop production, the sensor does not contact the measured medium, and there is no pressure loss.
● Suitable for measuring metal pipes, plastic pipes and other sound-transmitting materials.
● Built-in rechargeable battery, can work continuously for more than 12 hours.
● Intelligent on-site printing function to ensure the integrity of flow data.
