HydroLevelControl
Description
HydroLevelControl is a bundle of hardware and software designed to measure, present and control the level of fluids. Measurement is based on the hydrostatic pressure provided by the fluid above the pressure sensor. The measured pressure value is converted to a requested data format, according to inserted data, like fluid density, reservoir surface, etc. The measured value can be used to activate the visual alarm (blinking LCD display), sound alarm, and two relays. All this can be configured independently.
Take care that this device can be used only on atmospheric pressure. Installation in an over or under pressured environment can permanently damage the sensor and the device!
Background
The device has a pressure sensor, actually a pressure transducer, that is powered with 5 VDC. Depending on the pressure, it produces a different voltage on output that is measured and converted to pressure. Based on the fluid density, is possible to calculate the height of the fluid above the sensor. With the known height and the reservoir surface, can be calculated the volume and the mass of the fluid.
