Marking

In case of horizontal mounting in adhesive and viscous products,

the surfaces of the tuning fork should be vertical in order to reduce

buildup on the tuning fork. On the screwed version you will find a

marking on the hexagon. With this you can check the position of the

tuning fork when screwing it in. When the hexagon touches the seal,

the thread can still be turned by approx. half a turn. This is sufficient to

reach the recommended installation position.

In the case of flange versions, the fork is aligned with the flange holes.

When used in adhesive and viscous products, the tuning fork should

protrude into the vessel to avoid buildup. For that reason, sockets

for flanges and mounting bosses should be avoided when mounting

horizontally.

If the instrument is mounted in the filling stream, unwanted false

measurement signals can be generated. For this reason, mount the

instrument at a position in the vessel where no disturbances, e.g. from

filling openings, agitators, etc., can occur.

This applies particularly to instrument types with long extension tube.

To make sure the tuning fork of SITRANS LVL200E generates as little

resistance as possible to product flow, mount the sensor so that the

surfaces are parallel to the product movement.
