HydroLevelControl

Description

HydroLevelControl is a bundle of hardware and software designed to measure, present and control the level of a fluids. Measurement is based on the hydrostatic pressure provided by the fluid above the pressure sensor. Measured pressure value is converted to requested data format, according to inserted data, like fluid density, reservoir surface, etc. The measured value can be used to activate visual alarm (blinking LCD display), sound alarm and two relays. All this can be configured independently.

Take a care that this device can be used only on atmospheric pressure. Installation in over or under pressured environment can permanently damage the sensor and the device!

Background

The device have a pressure sensor, actually a pressure transducer, that is powered with 5VDC. Dependently of the pressure, it produce a different voltage on output that is measured and converted to a 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.
