Layout of the nameplate (example) Principle of operation Application area SITRANS LR140 is a radar transmitter for non-contact, continuous level measurement. It is suitable for liquids and solids in practically all industries. Functional principle The transmitter emits a continuous, frequency-modulated radar signal through its antenna.
Nonobservance of these instructions can cause damage to the device. Transport inspection The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with. SITRANS LR140 Operating Instructions, 08/2020, A5E50352144...

If you cannot maintain this distance, you should carry out a auto false echo suppression during setup. This applies particularly if buildup on the vessel wall is expected. In such cases, we recommend repeating the auto false echo suppression at a later date with existing buildup. SITRANS LR140 Operating Instructions, 08/2020, A5E50352144...

4.2 Mounting instructions Figure 4.6 Thread mounting If the reflective properties of the medium are good, you can mount SITRANS LR140 on nozzles longer than the antenna. The nozzle end should be smooth and burr-free, if possible also rounded. You will find recommended values for nozzle heights in the following illustration or the table.
Detailed project planning data can be found at the channel manufacturers and in the technical literature. The following examples serve as an overview for flow measurement. At smaller distances the measuring accuracy is reduced, see "Technical data". SITRANS LR140 Operating Instructions, 08/2020, A5E50352144...
