Bubbling system EPS-NE

July 2011

Integrated level sensing / integrated system monitoring

Description

The pneumatic level sensor EPS converts air pressure generated by the hydrostatic backpressure of the water level into a proportional, standard electrical signal.

It is possible to correct the zero point and scaling using a single button. False settings and system errors are indicated via LEDs.
The compressor is operated alternately in a duty cycle of approx. 20 %.
The bubble tube can be utilised in potentially explosive atmospheres.
A separate bubble tube and measurement lead arrangement is used to prevent condensation forming.
EPS-NE-S: a test program automatically tests the performance of the compressor daily.
A fault alarm is issued if performance characteristics deviate.

Application

    This module is utilised when extreme reliability is demanded; the EPS-NE bubbling system injects air bubbles into the medium it senses simultaneously and continuously the level of extremely dirty or chemically aggressive water and waste water.
