Supplying Huayu LS20B tell flow meter flow meter
20B type Propeller introduce high velocity Instrument Type 20B Propeller Flow Meter 1986 high technical appraisal by Ministry of Water Resources, the same type of instrument performance to foreign advanced level. 1988 by the Ministry of Water Resources Science and Technology Progress Award. 1990 was named national new products. ? In 1993 the US Geological Survey to participate in this instrument (USGS), the international flow meter than the measured tissue reference are:? China LS20B type, type PriceAA US, Germany and the United Kingdom OttC-31 type and other world famous Valeport BFM002 type flow meter . The results showed that the ratio of the measured characteristics of a good instrument, subject to US experts praise. Purpose and scope: 20B-type high Propeller Flow Meter is a large range of river hydrology speed equipment. Can be used for water rivers, lakes, channels and reservoirs, a variety of high, medium and low flow measurement, pressure pipes can also be used in power plants, and some scientific experiments, especially for high-speed and high-speed measurement. Features: ▲ particularly wide speed range, and only one propeller to meet a variety of high and low flow measurement ▲ good instrument bearing oil chamber dynamic sealing performance, high speed and high silt content in conditions hydrological station on the Yellow River, After a flood of flow measurement, bearing all without washable. Measured up to 4.3m / s, the maximum sediment concentration of 100kg / m3 ▲ imported high-quality plastic propeller manufactured with high impact strength, geometry, stability, resistance to atmospheric naturalization and other excellent performance. Long-term work in the field harsh natural conditions, instrument calibration coefficient K ▲ instrument stability constant low speed performance - in the friction characteristics of the available flow meter friction torque was monitored to ensure that low-speed performance and measurement instruments ▲ precision measurement instruments, Its installation flexibility, variety and reasonable directional device structure can be vertical, horizontal flow direction ▲ cater instrument structure strength, installation, support strong, can withstand 15m / s high-velocity impact, stable instrument performance, reliable work? ▲ instrument machine streamlined, and the tail counterweight to the built-in, the water resistance is small, the instrument without additional yaw moment, which can be operated stably main technical parameters: ● speed range: 0.05 ~ 15m / s ● propeller turning diameter: Φ120mm ● Propeller Hydraulic Pitch: 200mm ● output signal frequency: 2 Signal / rev ● verification formula relative error: When V≥VK, <1.5%; V
