1. Safety Instructions
1.1 Correct Usage
•
The EF200 measuring system is used to measure the flow of saturated steam,
superheated steam, air and water. Do not use to measure the flow of toxic,
flammable or otherwise hazardous fluids. Use this system only as intended.
•
The primarily measured variables are volume flow and temperature. From
these values, the device can use stored data on density and enthalpy to
calculate and output information such as mass flow and heat flow.
•
The manufacturer assumes no liability for damage or other accidents caused
by incorrect use of the instrument.
1.2 Dangers and Notes
All instruments are designed to meet state-of-the-art safety requirements,
have been tested, and have left the factory in a condition in which they are
safe to operate. They can, however, be a source of danger if used incorrectly
or for anything other than the designated use. Consequently, always pay
particular attention to the safety instructions indicated in these Operating
Instructions by the following symbols:

can result in minor or medium injury.
Note!
This symbol contains information on procedures and other facts which do not
result in personal injury.
1.3 Operational Safety
•
The EF200 measuring system complies with EMC requirements of both
IEC/EN 61326 and NAMUR NE 21, and the general safety requirements in
accordance with EN 61010-01.
•
EF200 fulfills all requirements for IP 66/67 to EN 60529.
•
The appropriate error messages are shown on the LCD display.
•
On power failure, the configuration data of the measuring system remain in
the EEPROM. The totalizer remains on the value last shown.
