Product liability and warranty
The BM 100 A TDR level gauge is designed solely for measuring the distance, level, interface and volume of liquids, pastes, slurries, solids and particulate materials. The BM 100 A TDR level gauge does not form part of an overfill protection system as defined in WHG nor is it concerned by the Pressure Equipment Directive (PED) 97/23/EC. Special codes and regulations apply to its use in hazardous areas. Responsibility as to suitability and intended use of these level gauges rests solely with the user. Improper installation and operation of our level gauges may lead to loss of warranty. In addition, the "General conditions of sale", found on the back of the invoice and forming the basis of the purchasing contract, are applicable. If you need to return the level gauge to the manufacturer or supplier, please refer to the information given in appendix A.

1 Mechanical installation
1.1 Handling and storage
1.1.1 Avoiding blows
Avoid hard blows, impacts and jolts when handling the BM100A.
Caution :
The probe is a critical gauge component. Do not damage– Handle with care!!!
Caution : fragile electronics
1.1.2 Avoiding bending
Rod/ Coaxial probes: support the probe to avoid bending.
Support probe here
1.1.3 Avoiding cable kinks or fraying
Do not coil the cable less than 400 mm / 16’’ in diameter. Cable kinks or fraying will cause measurement errors.
Handbook BM 100 A 7
1.2 Installation restrictions
Hazardous-duty systems (Ex, FM…)
refer to the supplementary instructions for gauges approved for use in hazardous locations
before installation.
check that the flange, gasket and probe materials are compatible with the product. Read the
information given on the converter nameplate, the flange markings and specifications in the approval certificates.
1.3 Mounting on a tank
1.3.1 Installation instructions: General notes
The fitter should give some thought to tank fittings and tank shape:
nozzle position in relation to the tank walls and other objects inside the tanks
(Warning : this free area will depend on the probe type selected: refer to later on in this section)
type of tank roof , i.e. floating, concrete, integral, etc; and base, i.e. conical,etc.
1.3.2 Installation instructions: Nozzle
Nozzle height
Recommendation (especially for single probes and powder applications):
Do not fit a nozzle longer than its diameter.
h ≤ Ød
Contact KROHNE if this relationship cannot be respected.
, where h = nozzle height and d = nozzle diameter.
8 Handbook BM 100 A
Nozzles extending into tank
Caution:
Do not use nozzles that extend into the tank. This will block the emitted pulse.
Process connection
For the gauge to make accurate measurements:
the tank process connection must be level.
ensure a good fit with the gauge process connection
the tank roof should not deform under the weight of the gauge
Objects (discontinuities) inside the tank that influence the probe EM (electromagnetic) field
Install the process connection far from protruding objects such as:
heating tubes
sudden changes in tank cross-section
tank wall reinforcements and beams,
weld lines and dip-stick pipes, etc...
Refer to the figure at the top of the following page.
TDR gauges generate electromagnetic fields when a measurement pulse is emitted. This field is affected by any nearby discontinuities and these will weaken and potentially block the emitted pulse. A minimum distance is recommended depending on the probe type to be installed. See the table on the next page for recommended free space dimensions. Alternatively, the fitter may use a reference chamber or stilling well. However, the chamber walls must be smooth (i.e. no visible weld lines), straight and vertical to maintain the pulse strength and gauge accuracy.
For clean applications only :
Coaxial (type D) probes may be used close to or touching objects or walls as the EM field generated by the probe is contained within the probe’s outer sheath (refer also to the EM field sizes given in the figures on the next page).

Electro static discharge (E.S.D.)
BM100 Standard and Ex gauge electronics are normally shielded up to 16KV against E.S.D.*. *For non-Ex powder applications, BM100A probes are protected up to 32 kV.
Note:
E.S.D. cannot be solved by BM100A E.S.D. protection. It is the customer’s responsibility to avoid E.S.D. by grounding the tank, product and probe installation.
1
Danger of injury
The probe may become electro
statically-charged during operation; earth the probe by pushing it against tank wall with a suitably isolated tool just before touching it to avoid receiving a shock.
2 Earth the entry pipe and product.
Product deposits on the nozzle and probe
Product build-up can occur under the nozzle: this may weaken the pulse. Avoid cavities that permit the build-up of deposits.
Tank roof deformation
Tank roofs should support loads of at least 3.5 tonnes / 7700lb for gauge installations using type K single cable probes and 3.6 tonnes / 7900 lb for gauge installations using type B twin cable probes without deformation.

3.4.1 General Information
Your BM100 A has now been installed on the tank and the necessary electrical connections have been made. Once the power has been switched on, it may be necessary to configure the gauge to:
display the readings using the correct units and reference point (level / distance ),
change the measurement range,
give the instrument an address so that it may be integrated into a network,
display volume readings by programming and using a volume calibration table (strap table).
We recommend that any changes to settings be noted on the configuration record supplied in appendix B, or recorded using PC-STAR, to enable KROHNE service personnel to provide a rapid response to any enquiries.
3.4.2 Configuration Procedure
The BM100 A starts up in operating mode displaying either information according to customer specifications or factory default values. The configuration mode (user menu) can be accessed and parameters modified by following the operator control concept summary below. Configuration procedure is described in more detail in section 3.4.3. Instruments may equally be configured individually using a remote display available in PC-STAR software for remote connections.
