Capacitance level sensors are a proved, as well as cost-effective solution for level measurement and point level detection in liquids and bulk solids. Various transmitters for continuous level measurement and switches for point level detection are available. The measurement of interface is also possible. The measuring principle is proven in millions of applications.

Hydrostatic level measurement is a simple and reliable method of measuring level. A submersible pressure sensor, regular pressure sensor or pressure gauge is lowered to or mounted at a specific depth (zero level). The sensor then measures the pressure caused by the weight of the liquid directly on top of it. Due to the hydrostatic paradox, the pressure sensor does not measure the complete volume in the tank above it, but only the liquid column vertically above it. The hydrostatic level measurement is thus completely unaffected by the shape of reservoir or vessel, just measuring the level by the weight of the liquid column above it. If the liquid and its specific gravity are known, the pressure measurement can be calculated as the distance from the zero level, where the sensor is located, to the surface of the liquid.
This single-chip operated transmitter has been designed for use in tanks, basins and canals and is characterized by easy calibration procedures.
If the probe is being used just as e two-threshold transmitter (min and max), calibration is performed by simply pressing two push buttons.
The complete configuration also including pump or alarm control, is achieved simply connecting the transmitter to a PC through the RS485 port.
The two transmitter relays may be setup as thresholds, as pump controls as self-diagnostic alarms, should malfunctioning occur.
The ultrasonic transducer and electronics are enclosed into a 2” GAS.
Smart Cost is intended to operate with temperatures up to 80°C and is appropriate for applications involving aggressive chemical acids or liquids and even stirring devices
