- LS300A portable flow rate meter (hereinafter referred to as portable flow meter) is the nanjing zhuoma electromechanical co., LTD., specifically for hydrological stations, factories and mines, environmental protection monitoring station, farmland irrigation and drainage, hydrogeology survey and other departments in the field of velocity of flow in open channel flow measurement.
- LS300 - A type of intelligent flow velocity meter rotors can form A complete set of new type velocity sensor, the sensor is to adopt advanced technology of the latest developed at the end of 2004, rotary pulp spiral Angle, pitch, production process and material are redesigned, rotary pulp diameter of 15 mm and 12 mm respectively (rotors reflective surface adopts advanced electroplating process, wear resistance, strong signal), the starting velocity of 1 cm/s or less, starting speed, speed
Specifications:
Velocity measuring range: 1 ~ 400 cm/s. Sampling time: 1 ~ 99 seconds to choose;
Figure 1. Portable flow meter installation drawing
The equipment is simple in structure, convenient in light, power saving, complete functions, high degree of automation, stable and reliable, and meet the national standard of open channel flow measurement, high temperature propeller configuration 80 degrees, is now a new type of portable velocity measuring instrument in China.
Measuring range: the velocity of 0.01 ~ 4. Om/s (domestic start minimum flow velocity meter) specifies the current meter water survey
<; 20 m
Use: is suitable for the channel, river, reservoir, measure and display directly due to water flow velocity measuring point
A full set of equipment: including current meter, display, and cable, do not need another purchase and form a complete set of equipment
Speed range: 0.01 to 4.00 m/s
Measurement error: 1.5% or less
Display: 4 x 16 LCD display
Measurement method: rod position measurement
Temperature range: - 20C to 50C
Power supply: DC8.4 V lithium ion rechargeable batteries, can work continuously more than 40 hours after full.
2. Measuring principle:
The instrument based on design of principle of open channel flow velocity area method to measure the velocity can get traffic s. Q = V (S for sectional area)
