Portable Ultrasonic Flow Meter
Product Introduction
Portable ultrasonic flow meter achieve non-touch flow measurement.As long as install the sensor outside the tube flow meter will work to measure flow rate,convenient and accurate. Ultrasonic flow meter can measure heat and temperature conveniently with temperature sensor. Ultrasonic flow meter is widely used in water supply,heat supply,water conservancy,metallurgy, chemical,machinery,power etc industries,used for production monitoring,flow comparison,temporary detection,hydraulic balance debugging,heating network balance debugging etc.
Features
1. High accuracy: Linearity: 0.5%, repeatability:0.2%, accuracy up to ±1%.
2.Non-contacting measuring: The ultrasonic flow meter will be adsorbed on the
outside of pipe, and then finish the measuring. Non-intrusive, clamp-on
transducer, no pressure drop, no pipe disturbance.
3.Wide measuring range: Several types transducer for selection, pipe size from
DN15mm to DN6000mm
4.Chinese & English menu: Chinese & English display, easy to operate.
5.Large capacity battery: Built-in rechargeable Ni-MH rechargeable battery,provide over 20 hours of continuous operation.
6.Built-in printer: Built-in mini thermal printer with instant and timing print function,also you can print more than 20 kinds of measuring results if you set in advance.
7.Built-in data logger: Uplink over 20 measuring data to computer or internet.
