2BASIC SAFETY REGULATIONS
2.1 Requirements for Personnel
The personnel carrying out the level transmitter installation, commissioning, diag-
nostics and servicing shall study this Manual and be permitted to operate the device.
When operating the equipment, the personnel shall use the required personal protec-
tion equipment in compliance with the standards at the enterprise.
2.2 Purpose
The level transmitters ULM-31А1, ULM-31-HF, ULM-31А1-HF, ULM-31-HF-F,
ULM-31А1-HF-F and ULM-31А1-HF-F-LC (hereinafter referred to as the “level
transmitters”) are designed to continuously contactlessly measure the level of liquid,
viscous or bulky products and intended for use in the process metering systems. The
level transmitters are used for measuring the level in the closed and open tanks and
suit for metering a wide range of products, such as acids, alkalies, water solutions,
food products, cement, coal, etc. Unintended use of device can result in the emer-
gency situation at the production facility, put the device out of operation and can be
the potential hazard source.
Specification of all models of levelmeters of series ULM-31 there are in the table 1.

2.3 Operational Safety
The device operational safety is ensured only in compliance with these manual
guidelines. To ensure operational safety and to observe the guarantee obligations, it
is prohibited to make any modifications in the device design. The operations with
the devices, except those set forth in this manual, can be performed only after the
manufacturer's official authorization.
2.4 General Guidelines on Safety
The level transmitters ULM-31А1, ULM-31-HF, ULM-31-HF-F, ULM-31А1-HF,
ULM-31А1-HF-F and ULM-31А1-HF-F-LC satisfy all current safety requirements
and standards. Depending on the version, the working emission frequency of the
level transmitters makes approximately 24 GHz for ULM-31А1 and 125±5 GHz for
ULM-31-HF, ULM-31-HF-F, ULM-31А1-HF, ULM-31А1-HF-F and ULM-31А1-
HF-F-LC. The emission power does not exceed 8 mW, which is significantly lower
than than the threshold limit values. The level transmitter is completely safe for the
human and the animals. To avoid the emergency situations at the production facili-
ty, it is allowed operating the device only in good working order. The level trans-
mitters are allowed for use only in the explosion-proof area.
2.5 Environmental Safety
Compliance with recommendations set forth in Sections “Packaging, Transportation
and Storage” and “Disposal” contributes to environmental protection.
