Press Release Summary = New patented procedure of IBJ Technology protects all pumps
against dry running.
The in line sensors can be manufactured for the process measuring
as Low Cost Product. OEM sensors can be integrated in pumps.


Press Release Body = Bases of the new technology of IBJ Technology of an dry running
protection for pumps (also: Pump protection) are new realizations for the
propagation of surface waves. The characteristics of Rayleigh-waves are used in new
sensors for applications in liquids and multi-phase mixtures. The new ultrasonic
sensors are protected as utility model and the procedure are announced with the
German patent office to the patent. The new technology differs from the well-known
state of the art, like time of flight or pulses technology, by its independence from
the transmission characteristics of the liquids. The well-known procedures for
reason lying idea, the evaluation of flutter echoes in a gate far outside of tube
sheet reflections and reflections in the sensor (diaphragm and own decaying), can be
used both for measurement by the wall (no contact of the sensor with the medium),
and for measurement with screwing in sensors in the tubing or container wall.
However bad transmission characteristics of the liquid have an unfavorable effect.
Against it if Rayleigh-waves to the attendance supervision or detection are used by
liquid phases, are the transmission characteristics of the liquid without influence
on the function of the sensors. Thus screwing in sensors for the Low cost range, and
fastidious measurements can be realized by the wall at containers and aggregates.
With screwing in sensors thereby an optimal signal transmission is guaranteed. The
height of the transmission tension can be minimized therefore. Also with unfavorable
reflectors (curved tube sheets, pump impellers etc.), which so not sufficient echoes
causes, can therefore the presence of a liquid be determined. For all processes and
applications, where the sensor contact with the medium does not disturb, thereby a
simple pump protection is possible. The measurements by the wall adhering the lack
of problematic start-up (couple conditions between sensor and tube sheet should be
defined and as reproducible as possible) becomes groundless thereby. Particularly
for solid-loaded liquids, salt solutions or suspensions generally, this technology
is favourably applicable.
