A portable open channel flow meters Overview 

 MGG / KL-DCB portable open channel flow / flow meter (portable open channel flow meter) is designed for hydrological monitoring, river flow monitoring, agricultural irrigation, municipal water supply and drainage, industrial wastewater and other industries open channel flow / flow measurement of a portable measuring instrument. It uses a special micro-power design, all-digital signal processing technology, makes the instrument more stable and reliable measurement, high accuracy, can be widely used in hydrology, irrigation, agricultural irrigation, drainage and other necessary measures and on-site and often moving None of the power supply. 

 Second, the characteristics of a portable open channel flow meter 

 Micro-power design, two 3.6V lithium battery, continuous operation for 3 years. 
 Measurement sensor with no moving parts, no winding, plug, long-term reliable continuous operation. 
 High-definition display with backlight LCD display, full Chinese menu display, simple operation, easy to use. 
 Flow meter can be displayed simultaneously, the instantaneous flow rate, the cumulative total number of measured water levels and other parameters. 
 Powerful, instrument do flow meter use, open channel flow meter also can be used (or input signal level access to water depth, then the channel or river cross-section data input can be realized flow measurement); can be used as a portable instrument, but also Fixed instrumentation to use to do. To meet the different sections of open channels, culverts, river flow and flow measurements. 
 Type of output: pulse output, RS-232, RS-485, GSM / GPRS wireless communication and other optional remote. 
 Data storage function, holds up to 1000 sets of data, and data storage time interval can be set, and data query. 
 Third, the main technical parameters of a portable open channel flow meter 

 Measuring range: flow measurements 0.005m / s ~ 10m / s, channel width ≤ 20m, channel depth ≤ 20m, the slope coefficient of 0 to 10. 
 Accuracy: ± 1.0%. 
 Power Supply: 3.6V internal lithium battery 2, continuous working time of 3 years. 
 Display: LCD large screen liquid crystal display, full Chinese display, can display flow rate, flow rate, cumulative volume, water level measurements. 
 Output signal: pulse output 0.00001 ~ 1m3 / P, can be set (passive optocoupler output); frequency output 1 ~ 1000Hz, can be set. 
 Communication: RS-232, RS-485, GSM wireless data remote (optional).
