Description

The model FLM-Tx-FLEX magnetostrictive level transmitter is used for high-accuracy, continuous level detection of liquids, also with long insertion lengths.

The model FLM-Tx-FLEX is fitted with a flexible probe tube in the form of a stainless steel spiral armour.

For approvals, see page 4

Level transmitter in flexible version, model FLM-TAI-FLEX

At the lower end of the sensor, there is a magnetic foot, which serves both to fix the stainless steel corrugated tube to the tank floor and as a ballast weight. Due to the flexible probe tube, the FLM-Tx-FLEX has an advantage in installation in applications with low ceiling clearances. Transport, due to the flexible design, is also easier than with a rigid probe. Interface measurements are also possible with the flexible version.

Special features

Probe length 1,500 mm … 22,000 mm [59.06 ... 866.14 in]
High accuracy of ± 2 mm [± 0.08 in] over a wide measuring range
Very high resolution of < 0.1 mm [0.004 in]
Explosion-protected versions possible
