LS1206B Spiral Paddle Type Velocity Tester Water Flow Meter CBL-1 Pump Flowmeter
This instrument is characterized by small size, shape, lightweight, compact structure, precision, convenient carrying and use, suitable for small rivers, river shoal, irrigation and drainage channels to sell water period, water conservancy survey, runoff experiment, and are widely used for measuring the efficiency of hydraulic machinery and experimental tests of small flow efficiency of pumping station monitoring, sewage pipe. Seepage flow measurement as well as the environmental protection department.
This instrument as the CBL - 1 type pump flow meter, in July 1983 by the Ministry of water identification, agreed that the instrument is used for medium and small single station traffic detection, with equipment installation, simple and convenient operation, stable performance, reliable operation, accuracy in accordance with international standards ISO-2548-73 "C" level precision flow test. After the nationwide popularization and use, users agree that it has the characteristics of small input and high output. This instrument is widely used in the small channel measurement of farmland irrigation. Because of the good dynamic sealing performance of the shaft of the instrument, the sediment concentration in the irrigation area quoted by the Yellow River water irrigation reaches 20kg/m3, and the instrument can still work normally. The instrument in the mounting structure on a little modification, it can be used for speed measurement, and in the South China Sea marine survey on the successful completion of the task of speed measurement.
