OUNTING ON THE TANK
4.2.1.
Installation instructions: general notes
Prior to installation the fittings and the shape of the tanks are to be taken into account. Nozzle position in relation to the tank walls and other objects inside the tanks.
(Warning: this free area will depend on the probe type selected: refer to later on in this section) design of the roof of the tank i.e. floating, concrete, integral, etc;
and base, i.e. conical, etc. Before installing it, please remember to: Disconnect the power supply, the gauge may be installed when the tank contains the medium.
Threaded process connections
Nozzle height
Nozzles penetrating into tank
The simplest and most economic way is to mount
the MicroTREK 2-wire directly on the tank with
the 1" (1½") BSP or 1" (1½") NPT threaded
connection.
Do not fit a nozzle longer than its diameter,
especially for single probes and powder applications.
h
≤
Ød, where
h = nozzle height and
Ød = nozzle diameter
Contact NIVELCO if this relationship is not feasible.
Caution: Do not use nozzles that
penetrate into the tank. This will disturb the
emitted pulse.
