Model: ULSS-1B
The ULSS-1B Online Ultrasonic Doppler flow meter can measure the flow velocity and water depth in real-time, it’s designed according to the “ Doppler effect” principle. it has no rotary parts, it can test transient flow velocity and average velocity. it’s kind of advanced hydrological instrument.
Features
High accuracy, wide range, can test both the weak and high current
High sensitivity, high resolution, no limit by the start flow velocity
Fast response speed, can test transient velocity and average velocity
Linear test graph
No mechanical rotary part, so have no convolving problem caused by sediment or water plants, specially suitable for the liquids with high content of suspended solids and water plants
Large LCD display with backlight
Mass storage unit can save 8000 groups data
Time function avaliable
Data software available for storage, print, and output
Real time display flow velocity and temperature value
Automatic and manual test mode available
GPRS can transit the test data to up to 5 designated users terminal
