Application considerations

For most liquids, including coating, aerated liquids and slurries, the function is virtually unaffected by
flow, turbulence, bubbles, foam, vibration, solid particles, build-up, or properties of the liquid.
The 2130***E version of the level switch operates in high process temperatures of –94 to 500 °F
(–70 to 260 °C).
The 2130***M version of the level switch operates in mid-range process temperatures of –40 to 356 °F
(–40 to 180 °C).
The level switch can be mounted in an open or closed tank, or pipe. There is a wide range of threaded,
flanged, and Tri Clamp process connections.
Important
There should be no risk of 'bridging' the forks (see
'bridging' of forks are dense paper slurries and bitumen.

OK
Application guidelines
Ensure the process is operating within the level switch operating temperature and pressure ranges

(see
Ensure the liquid viscosity is within the recommended viscosity range

(see
Check that the liquid density is higher than 37.5 lb/ft

when ordered with the Low Density Range option (see
Liquid density affects the switching point e.g. dry-to-wet (see

Check for risk of build-up on the forks.

Avoid situations where drying and coating products may create excessive build-up. Problems may
occur if the product coats and then dries, causing caking.
Check the solids content in the liquid.
