General safety instructions
The following general safety instructions must be observed:
No liability is accepted for damage arising through non-observance of the operating
instructions.Read the operating instructions carefully and observe them.
The operator-owner is responsible for the observance of the operating instructions.
Installation, removal and installation work may only be carried out by specialist personnel.
Do not use KRAL sensors outside the operational limits specified in the "Technical data" section. In the case of operating data that do not agree with the specifications in the "Technical
data" section, contact the manufacturer. In order for the warranty to remain valid, corrective maintenance during the warranty period require the express permission of the manufacturer.
Observe the general regulations for the prevention of accidents as well as the local safety and operating instructions.Observe the valid national and international standards and specifications of the installation
location.Implement all the supply lines without faults.The sensor system (sensor, transducer and lines) may not be located in the area of strong,
high-frequency electromagnetic fields, such as those emitted e.g. from power lines, electric motors, frequency converters, etc. This can lead to erroneous measurements or the destruction of the sensor system.
In case of plants with an increased potential of danger to humans and/or machines the failure of a sensor may not lead to injuries or damage to property.
Always equip systems with an increased potential of danger with alarm equipment.Maintain and check the protective/alarm equipment regularly.
The pumped liquids may be dangerous (for example hot, dangerous to health, poisonous,
combustible). Observe the safety regulations for handling dangerous materials.Pumped liquids can be subject to high pressure and can cause damage and/or personal injury
should leaks occur.Depending on operating conditions, the service life of the sensors is limited due to vibrations, temperature influences or deterioration. The operator-owner is responsible for regular
inspection.All parts which jeopardize safe operation must be replaced regularly.
Abnormal operating mode or visible damage prohibits further use.

Function description Description
Functional principle
The sensors from the BEG 56 and BEG 47C series are optimized for use in combination with KRAL volumeters of the OME series. The sensor samples the flanks of the measuring screw and generates a specific number of pulses per
flow volume unit - depending on the size and working point. This device-specific characteristic is called the K-factor (unit: Pulse/Liter) and can be found on the rating plate of the volumeter and the enclosed calibration certificate.
On sensor plug 3 of the sensor BEG 56 there are a green and a yellow LED. The supply voltage can be checked using the green LED. Upon rotation of the measuring screws, the yellow LED begins to flash in the rhythm of the pulse signal and thus facilitates a control of the signal output.
The sensor insert of the BEG 47C is mounted in a dry sleeve 5 . The dry sleeve allows the sensor insert to be mounted without contact to the liquid to be measured.

Technical data Intended use
KRAL Sensors of the BEG 56 and BEG 47C series are intended exclusively for use with KRAL
volumeters of the OME series. The sensors may only be used within the operational limits described within this chapter.
Use not as intended
The sensors are not suitable for all other use except for use with KRAL volumeters. The sensors may not be used outside the operational limits described within this chapter. Operating data which deviate from the values can lead to damage. If there is any doubt whether deviating operating data can cause
damage, inform the manufacturer.
Operational limits
The following table indicates the operational limits of the sensors which may not be exceeded.
