The hydrostatic level transmitter NIVAPRESS SGE-25 is convenient for measuring clear liquids, stored in tanks and wells. It is recommended for monitoring and control of submersible pumps systems.
The probe measures the hydrostatic pressure due to the liquid column (difference from total pressure above the sensor and the atmospheric pressure through a capillary built in the cable).
The sensor is a piezo-resistive detector, protected with a diaphragm in Hastelloy. The PCB delivers an analogical signal (4-20 mA or 0-10 V) directly proportional to the height of liquid. The anti-surge device protects the instrument from damages caused by atmospheric disturbance or high power apparatuses.
