62076-EN-190704

1  For your safety

1.1  Authorised personnel

All operations described in this documentation must be carried out 

only by trained, qualified personnel authorised by the plant operator.
During work on and with the device, the required personal protective 

equipment must always be worn.

1.2  Appropriate use

The MINITRAC 31 is a sensor for density measurement and level 

detection.
You can find detailed information about the area of application in 

chapter "

Product description

".

Operational reliability is ensured only if the instrument is properly 

used according to the specifications in the operating instructions 

manual as well as possible supplementary instructions.

1.3  Warning about incorrect use

Inappropriate or incorrect use of this product can give rise to applica-

tion-specific hazards, e.g. vessel overfill through incorrect mounting 

or adjustment. Damage to property and persons or environmental 

contamination can result. Also, the protective characteristics of the 

instrument can be impaired.

1.4  General safety instructions

This is a state-of-the-art instrument complying with all prevailing 

regulations and directives. The instrument must only be operated in a 

technically flawless and reliable condition. The operator is responsi-

ble for the trouble-free operation of the instrument. When measuring 

aggressive or corrosive media that can cause a dangerous situation 

if the instrument malfunctions, the operator has to implement suitable 

measures to make sure the instrument is functioning properly.
During the entire duration of use, the user is obliged to determine the 

compliance of the necessary occupational safety measures with the 

current valid rules and regulations and also take note of new regula-

tions.
The safety instructions in this operating instructions manual, the na-

tional installation standards as well as the valid safety regulations and 

accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device 

beyond that described in the operating instructions manual may be 

carried out only by personnel authorised by the manufacturer. Arbi-

trary conversions or modifications are explicitly forbidden. For safety 

reasons, only the accessory specified by the manufacturer must be 

used.
To avoid any danger, the safety approval markings and safety tips on 

the device must also be observed and their meaning read in this oper-

ating instructions manual.
