4.2 MOUNTING ON THE TANK
4.2.1 INSTALLATION INSTRUCTIONS: GENERAL NOTES
Prior the installation some consideration is to be made regarding tank fittings and tank shape. 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) type of tank roof, i.e. floating, concrete, integral, etc; and base, i.e.
conical, etc. Whenever working on an installation, remember to: Disconnect the power supply before starting work. However, the gauge may be installed when the
tank contains product.
Threaded process connections
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.
Nozzle height
Do not fit a nozzle longer than its diameter, especially for single
probes and powder applications
h ≤ Ød
, where
h = nozzle height and
d = nozzle diameter
