Product Description
In many industries, level measurement sensors fall into two main types.
Point level measurement sensors are used to mark a single discrete liquid height-a preset level condition. Generally, this type of sensor functions as a high alarm, signaling an overfill condition, or as a marker for a low alarm condition.
Continuous level sensors are more sophisticated and can provide level monitoring of an entire system. They measure fluid level within a range, rather than at a one point, producing an output that directly correlates to the level in the vessel. To create a level management system, the output signal is linked to a process control loop and to a visual indicator.
There are many ways to measure continuous level of liquid. But most of them are very expensive. We have developed a very low cost high accuracy capacitive sensor which produces a output signal, that is directly proportional to the height of the liquid. You may get the volume of the liquid directly if the tank is calibrated. The calibration process may be done by connecting the device with a Computer/Laptop through serial port(RS232). This device can periodically store data(Liquid level/Volume, Temperature) up to one month and can be downloaded through the software provided with it.
