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:

BK – Black

WH – White

BU – Blue

YE – Yellow

BN – Brown

GN – Green

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).
