Continuous Level Measurement
Hydrostatic level probe APC-2000ALW/P and PCE-28P - Aplisens

Application
Hydrostatic level probes are applicable to measure levels of liquids in open tanks, channels, measuring constrictions of open channels, streams etc.
 

Installation
The probe may be installed in any manner subject to the following conditions:
- the expected maximum level of liquid may not cause flooding of the electronic circuits;
- if a flange fastener is to be used to install the probe in the tank cover, it should be ordered alongside with the probe, as these fasteners are to be
mounted during the probe manufacturing.

Hydrostatic level probe SGE-25C Aplisens

Application
The SGE-25$ and SGE-25C probes are applicable to measure levels of liquids containing contaminants or suspensions. Atypi-
cal use for this probe is the measurement of levels of liquid waste in intermediate pumping stations, fermentation chambers,
setting tanks etc.


Principles of operation, design
The probe measures liquid levels, basing on a simple relationship between the height of the liquid column and the resulting hydrostatic pressure. The pressure measurement is carried out on the level ofthe separating diaphragm of the immersed probe and is related to atmospheric pressure througw a capillary in the cable. The use of a special separator with a large uncovered diaphragm minimizes the metrologioal effect of sediment deposit on the diaphragm surface. This enables the probe long lifetime and proper work in contaminated media (even in the presence of abrasives, such as sand) and facilitates cleaning with a delicate stream of running water (washing with water under pressure may damage the probe). The active sensing element is a piezoresistant silicon sensor separated from the medium by an isolating diaphragm. The elecrronic amplifier, which works in combination with the sensor, and is meant to standardize the signal, is additionally equipped with an overvoltage protection circuit, which protects the probe from damage caused by induced interference from atmospheric discharges or from associated heavy current engineering appliances.

Hydrostatic level probes SGE-25 / SGE-16 - Aplisens

Application
The SGE-25 hydrostatic level probe is applicable to measure liquid levels in tanks, deep wells
or piezometers. The SGE-16 probe is a specialized device designed to measure water levels in narrow diameter piezometers
or wells.
 

Principles of operation, construction
The probe measures liquid levels, basing on a simple relationship between the height of the liquid column
and the resdting hydrostatic pressure. The pressure meaurement is carried out on the level of the separating
diaphragm ofthe immersed probe and is related to atmospheric pressure through a capillary in the cable.
