DEVICE DESCRIPTION 2
2.2 Device description
The BM 500 level meter utilises the potentiometric measuring principle and can be used in all
medias that have a minimum conductivity of 50 μS/cm.
From the low resistive measuring rod a high frequent current is fed through the media to the
tank wall. The voltage between the tip of the rod and the tank wall is measured. This output
voltage is proportional to the level in the tank.
The measurement is unaffected by temperature and adhesive media.
The device is ideal for measurements in small vessels with tough, pasty or strong adhesive
media, such as ketchup, honey, and toothpaste. The integrated electronics provide a 4...20 mA
output.
The device has automatic recognition of top/buttom mounting position. Even angled installation
is possible.
In non-conductive tanks, e.g. plastic, a reference rod must be installed (order a standard
LS 7200 without electronics).
The BM 500 is available as compact and remote version. The remote version is recommended for
applications where the ambient temperature at the measuring point exceeds +60°C / +140°F.
Due to the high process temperature limit, the device is well suitable for CIP and SIP processes.
The hygienic installation is guaranteed by using one of the hygienic weld-in sleeves. For further
information refer to the specific data sheet "Hyg. accessories".

3.1 Installation requirements
• Be sure that the measuring rod has the correct depth of immersion when placing your order.
The sensor cannot
• Use only the recommended sleeves or adapters. If other systems are used, no guarantee can
be given for proper functioning or leak-tightness.
• The connection thread must have electrical contact with the metal vessel. If this is not
possible, use a separate grounding cable to meet this condition.
• Do not use Teflon or paper gaskets.
• The tightening torque for the sleeve should be 20...30 Nm.
• If the vessel is electrically non-conductive (e.g. plastic tank), the frame potential can be
established via an additional ground electrode, which is electrically connected to the
connection thread. E.g. a standard LS 7200 without electronics. Consult your local contact for
ordering assistance.
• Make absolutely sure that the measuring rod cannot come into contact with the wall of the
vessel. Also take into consideration the possibility of rod deflection caused by moving
product.
• For distances of less than 100 mm / 3.9" (e.g. when installed in vertical pipe runs) the sensor
rod should be located parallel to the wall, otherwise conditions of non-linearity can occur.
For large distances non-parallelity of the rods can be allowed.
• The level meter measures linearly over the full rod length.

3.2 Process connection
The hygienic 1" process sleeve is easy to weld into tanks or pipes. This kind of assembly allows
installation in conformity with standards of hygiene such as FDA. The G1 connections can be
mounted in any counter thread acc. to ISO 228.
Various hygienic adapter sleeves are available for fitting to other process connections. For more
information refer to chapter "Appendix" or data sheet "Hyg. accessories".
The level meter can be installed either from top or bottom.

3.3 Mounting of 3A marked products
The 3A mark is valid only when the product is mounted in a 3A marked counterpart and installed
acc. to the installation manual. Use also a 3A marked O-ring or gasket if relevant.
The 3A marked products conform to the 3A sanitary standards criteria. Materials and surfaces
fulfill the FDA demands.
EPDM O-rings supplied with 3A marked products are conform to sanitary standards class II (8%
milk fat).
1 Use only 3A approved counterparts.
2 The inspection hole should be visible and drained. Face it downwards so that possible leaking
can be observed.

5 OPERATION
5.1 Start-up
Before connecting to power, please check that the system has been correctly installed.
This includes:
• The device must be mechanically safe and mounted in compliance with the regulations.
• Check that the measuring rod is not in contact with the vessel wall.
• Check the leak-tightness at the leakage inspection hole of the sleeve or adaptor.
• Make sure that the M12 plug is properly connected or the M16 cable gland properly tightened.
• The power connections must have been made in compliance with the regulations.
• Check that the electrical operating data of the power supply are correct.
5.2 4 and 20 mA setting
• The green LED indicates that supply voltage (> 18 V) is present (operation indicator).
• The 2 red LEDs show different flashing rates (LED monitor), according to the control of the
current output.
• The level meter can be installed at the top or the bottom of the tank.
• The level meter is factory calibrated for installation from the top. This corresponds to 4 mA at
the lower rod end and 20 mA at the upper end (lower part of the conical section of the
measuring rod; see drawing on page 11). When installed from the bottom, the current will
drop down step by step until the tank is empty or the current hits 2.4 mA.
• 4 and 20 mA setting:
4 and 20 mA setting:
4 and 20 mA setting:4 and 20 mA setting:
This procedure is only required when a smaller measuring range is needed than the
maximum measuring range calibrated from factory or in case of a big difference in
conductivity with tap water exits. When two liquids are present - choose the liquid with the
lowest conductivity for the lowest level setting.
1. Bring level to 0% level - then press for > 3 seconds the 4 mA setpoint key. The 4 mA red
LED is "ON" which confirms the setting.
2. Raise level to 100% level - then press for > 3 seconds the 20 mA setpoint key. The 20 mA
red LED is "ON" which confirms the setting.
• In bottom mounting position:
In bottom mounting position: The level meter will show a negative value, when the level

representing the 20 mA level, accidently was set at a lower level than the 4 mA level.
• Resetting to factory calibration:

Resetting to factory calibration:Resetting to factory calibration:
Press simultanously for > 3 seconds both setpoint keys, both red LEDs will continously flash
to indicate that the level meter is reset. Repeat above calibration procedure for setting the 0%
and 100% values.
• The "dry" signalling threshold is set simultaneously with the low level calibration. When the
conductivity measured here is undershot, the sensor signals the "dry" condition with a
current output value of 2.4 mA. Given different products with widely differing conductivity, the
4 mA adjustment should be carried out using the least conductive liquid.

BM 500
The liquid is stored in a tank, connected to ground. The immersed measuring rod is a low
resistance rod where the ends are powered by an AC generator operating in the lower kiloherz
frequency range.
Between the rod and the tank wall is an endless amount of high level resistances. Since they
connect to the same potential (the tank wall) they can be shown as two equivalent resistances,
R1 and R2 connected to an imaginary center point. A high resistance input amplifier is connected
between the generator and the tank wall.
Since the generator is supplying a high range current it will create a significant voltage drop
across the low resistance rod. The resistances R1 and R2 form a voltage divider in range of the
immersed part of the rod. Output from this divider will indicate half the level of the liquid. The
amplifier then calculate the actual level of liquid from 0 to 100%.
The formula is:
= 1/2 x media level (%) x U

out
Media level (%) = U

x 2
The level measurement is insensitive to adhesion.
CAUTION!
It is very essential that the media conductivity is homogenious. Otherwise R1 will not be equal to
R2 and the output voltage will be influenced.
