Smart river open channel magnetic flow meter digital sea water flow sensor

 

 

LDM-51 Intelligent open channel sea water flow sensor
National patent No.: 201320255748.7

LDM-51 Open channel flow meter is professional economic and practical instrument during industry research and development. It’s for agricultural irrigation, open channel diversion, municipal water supply and drainage, sewage treatment etc. It plays an irreplaceable role in a lot of engineering example.
For example the River Diversion Project, water divert, city water supply, the Power large enterprises, reservoir water supply, which has higher applicability to the flow section of the shape, rectangular, trapezoidal and the flow measurement of culvert.

Flow display	1000
Communication way	GPRS,RS-485[(MODBUS(RTU)]communication interface
Water level measurement	ultrasonic level gauge, pressure-type liquidometer, float ball liquid level indicator, magnetostriction liquidometer etc.

 

Main features of sea water flow sensor
1. Dual power supply working, Selective use of AC / DC selective, solar energy work more energy efficient;
2. Display complete, can be measured water level display, flow velocity , the flow, accumulate flow at the same time;
3. Interface standard, RS-485[MODBUS(RTU)] communication interface, 4-20mA current signal, alarm output;
4. Data save, keep records of setting parameters and measuring value when power outage for a long time;
5. Multiple input interface, support the flow velocity , water level sensor 4-20 mA signal input;
6. The sensor of low flow resistance, measurement is not affected by flotage, sediment concentration, tributary backwater, and variation of water level.
7. Easy construction, the reconstruction of the old project is convenient, the new project installation is simple;

8. Level and velocity signal collector are integrate.
