Height variation.The variation that sensing water level encoder of ining succession above calculates water level obtains data.The disadvantage is that: at high cost, running resistance
Greatly, data dissipate more partially.
2, pressure type water level sensor, the sensor is directly proportional according to depth of water coefficient, and water is deeper, and the pressure of sensor is also
It is bigger.Fix the monitoring point of the sensor, so that it may show the height data of the water level, the disadvantage is that: at high cost, underwater undercurrent meeting
Monitoring data are interfered, suitable for fixed monitoring scheme
3, air bubble type water level sensor, the monitoring scheme which is made of pressure sensor and tracheae, the program can
Not have to sensor to be put under water, it is only necessary to which the fixed bubble that will produce by boasting leads to tracheae.To judge the speed of bubble
The depth that must be discharged, the deeper pressure of water is also big, and bubble outflow is slower.The disadvantage is that: the biggish local monitoring data of SEA LEVEL VARIATION
Have error.
4, ultrasonic water level sensor, the sensor utilize air echo ranging principle, are monitored the measure of the change of water
The height of water level out, to obtain the data that we want.Disadvantage: at high cost, installation and debugging are difficult, and data processing is cumbersome.
A universal disadvantage of these sensors is exactly that the cost is relatively high, for this infrastructure device, this point
The multiple accumulations of the gap of cost are got up, and that is exactly an inconceivable astronomical figure, so need a kind of stability good, cost
Cheap water level monitor meets the wide market demand.
