Installation

Coaxial probe

The coaxial probe can be guided by a tube welded

on the tank bottom. Tubes are customer

supplied. Make sure the probe can move freely in

order to handle thermal expansion.

Rigid twin lead probe

The Rigid Twin Lead probe can be secured to the

tank wall by cutting the center rod and putting a

fixture at the end of the outer rod.

The fixture is customer supplied. Make sure the

probe is only guided and not fastened in the

fixture to be able to move freely for thermal

expansion.

Flexible single lead probe

The probe rope itself can be used for anchoring.

Pull the probe rope through a suitable anchoring

point, for example a welded eye, and fasten it

with two clamps.

The length of the loop will add to the transition

zone.The location of the clamps will determine

the beginning of the transition zone. The probe

length should be configured as the length from

the underside of the flange to the top clamp. See

section “Transition zones” on page 16 for further

information on Transition Zones.

Alternative chuck for flexible single lead

probes

Loosen the screws. Pull the probe rope through a

suitable anchoring point, for example a

welded-eye.
