q) Horn adapter ST–G1 (ULM–53L–02) and
ST–G1,5 (ULM–53L–06) for improved
transmitted signal reception can be used in
open channels, sumps, tanks, etc.
r) Horn adapter increases the radiation direc-
tivity of acoustic waves, improves reception
of weak echoes (unstable level surfaces,
solid materials, etc.) and reduces the risk
of false reflections.
s) The horn adapter is installed to level meters
via process connection G1" (ST–G1) or
G1½" (ST–G1,5).

ULM–53L–__–I and ULM–53L–__–U
The ultrasonic level meter is designed to
be connected to supply unit or to control-
ler through two or three-wire 5 m long
cable. Connection diagram as shown in
Fig. 14 and 15.
„ULM–53L–__–M"
The connection is done by means of
shielded four wires cable directly into a
binary input of control system (RS–485).
Connection diagram as shown in Fig. 16.
Shielded cable length is 5 m.
Legend:

Make the electric connection in voltage-free state!
In case of strong electromagnetic interferences (EMI), parallel cable ducting with power lines, or when
cable length exceeds 30 m we recommended to use shielded cable (for "I" and "U" variants only).
